Jazz Theory





Jazz Theory: From Basic to Advanced Study is a comprehensive textbook ideal for Jazz Theory courses or as a self-study guide for amateur and professional musicians. Written with the goal of bridging theory and practice, it provides a strong theoretical foundation beginning with music fundamentals through post-tonal theory, while integrating ear training, keyboard skills, and improvisation. It includes a DVD with 46 Play Along audio tracks and a companion website, which hosts the workbook, ear training exercises, and audio tracks of the musical examples featured in the book.

Key Features:

• Includes 352 musical examples ranging from original lead sheets of standard tunes (“Autumn Leaves,” “Dream Dancing”), jazz instrumentals (“Confirmation,” “Moose the Mooche”), transcriptions (“Moose the Mooche,” “Line Up”), and original compositions (“Billie’s Dance,” “Infidels Bounce”), to fully realized harmonic progressions, sample solos, and reharmonized tunes (“All the Things You Are,” “Stella By Starlight”).

• A DVD with 46 Play Along audio tracks featuring a Piano Trio, Guitar Trio, and Hammond B-3 Trio allows students to practice improvisations over different tunes and chord progressions.

• Carefully graded exercises consisting of part-writing tasks, ear training drills, keyboard realization, melody harmonization, model composition, and improvisation.

• Ear training exercises including rhythmic dictation, harmonic dictation, chord recognition, singing, and set-class identification.

Dariusz Terefenko is Associate Professor of Jazz Studies and Contemporary Media at the Eastman School of Music at the University of Rochester.





Jazz Theory: From Basic to Advanced Study is brilliantly organized, thoughtfully paced and sequenced, and concisely detailed. It is the most articulate and exhaustive exploration of jazz theory that I’ve witnessed, making it a terrific resource for classroom instructors, private teachers, and students wishing to tackle this broad subject independently. This superb text is a welcome gift to jazz education. Bravo Dariusz!

—Fred Sturm, Professor of Jazz & Improvisational Music, Lawrence University Conservatory of Music



This publication is the most comprehensive presentation I have seen that methodically illustrates the principals of Jazz theory and provides essential groundwork for musicianship skills. Professor Terefenko offers a valuable textbook for both instructors and students.

—Pete Woodard, Professor of Jazz, University of Hartford



I don’t think that I’ve ever seen a book on Jazz Theory that was this well written! Not only is it well-written, well-researched and thorough, it’s very accessible and understandable regardless of one’s age or level of experience. If someone asked me to recommend one book that would help them to be a better jazz musician, I would recommend this one without hesitation!

—Dennis Mackrel, Musical Director of the Count Basie Orchestra

Preface

* * *





While teaching a theory course at the Eastman School of Music, a student came up to me after class and said: “I really enjoyed your course, but I wish that instead of the countless handouts you gave us, you could write a book. It would give us something more permanent—a kind of lasting documentation of your teaching methodology that we really enjoyed.” I responded that I would consider his request and began ruminating about the idea of writing a book. I quickly realized, though, that the transition from class handouts to a well-organized textbook was not as straightforward as my eager student wanted me to believe.

Jazz Theory: From Basic to Advanced Study is an innovative textbook designed for undergraduate and graduate jazz students, and for an ever-increasing population of classical students interested in jazz theory and improvisation. The overall pedagogy combines theory, ear training, keyboard skills, and improvisation into a comprehensive whole that enables more effective internalization and understanding of various theoretical topics discussed in the book. Intended for 2-, 3-, or 4-semester curricula in jazz theory, ear training, improvisation, harmony, keyboard skills, jazz literature, and jazz composition courses, it can also be used as a self-study guide for professional musicians unaffiliated with an institution. Conveniently divided into three parts, each major section is written with a specific group of students in mind: Part One for beginners, Part Two for intermediates, and Part Three for advanced students. While each of these sections creates a separate whole, they also form a comprehensive and cross-disciplinary narrative when taken together.

In addition to the traditional topics covered in the chapters on Music Fundamentals, Harmonic Function, Four-Part Chords, Five-Part Chords, Modes, The Blues, and Jazz Lead Sheets, the book engages the reader in an extensive discussion of Chord—Scale Theory, Bebop, and Pentatonics and Hexatonics. The book also offers some original thoughts on the phrase structure of standard tunes in the chapter on Phrase Models, and explains the principles of vertical and horizontal harmonization in the chapter on Jazz Reharmonization. The connection between theory and practice is an underlying motto of the book; this issue comes to the fore in the chapters on Improvisation, Bebop Blues, “Confirmation,” “Moose the Mooche,” and “Line Up.” The importance of acquiring basic keyboard skills as a necessary tool for developing comprehensive musicianship is addressed in the chapters on Keyboard Textures, Idiomatic Jazz Progressions, and Voicings. To establish more meaningful connections between different branches of theoretical discourse and jazz theory, the chapters on Phrase Models, The AABA Song Form, The ABAC Song Form, and Extended and Unusual Song Forms touch on various aspects of formal and modified Schenkerian theory, while the final chapter, Post-Tonal Jazz, makes inroads into atonal music theory, offering innovative and thought-provoking ideas for the advancement of this type of interdisciplinary research.

GOALS



* * *



Improvisational Skills

The ultimate goal of jazz theory is to improve one’s improvisational skills. The Play Along DVD includes 46 tracks recorded by the fine musicians of the Eastman School of Music: Prof. Jeff Campbell (bass), Prof. Rich Thompson (drums), Gabe Condon (guitar), and myself (piano and Hammond B-3). In Chapter 10, the student is asked to use the Play Along DVD, first in the context of the blues and modal scales, and subsequently in the context of complete standard songs and jazz instrumentals. Initial tracks—with the exception of the major and minor blues—place an emphasis on playing in 12 keys. Each track on modes, then, covers 12 16-bar or 8-bar phrases, each in a different modal area. Similarly, the II–V–I or V–I progressions are performed in 12 keys using different paths through the 12 tonal areas. To offer experiences closer to real-time performance situations, each track is recorded at a different tempo, rhythmic feel, and with either piano, Hammond B-3 or guitar as a comping instrument.

Expanding Repertory

Aside from pedagogical concerns, a subsidiary goal of this text—one hopefully appreciated by song aficionados—is to expand the repertory of standard tunes. Chapters 21–24 discuss harmonic designs, formal models, harmonic variations, and interpretations of standard tunes. In addition to the original sheet music (with the composer's piano accompaniment, verses and lyrics) of “My Romance,” “Have You Met Miss Jones?” and other tunes, these chapters include the titles of 999 other songs based on the similarity of their tonal and formal designs. By classifying standard tunes according to the harmonic structure of the A section and the type of harmonic motion in the bridge, I hope that students can quickly learn a large number of tunes. Appendix G on the companion website includes an alphabetical list of titles (with their composers and lyricists) mentioned in these chapters, and Appendix H (companion website) contains a list of 200 essential standard tunes (out of the 999) that every jazz musician should know.

HOW TO USE THE COMPANION WEBSITE



* * *



www.routledge.com/textbooks/cw/terefenko

The companion website contains three large sections: WORKBOOK, RECORDINGS, and APPENDICES/AUXILIARIES.

Workbook

The WORKBOOK sections closely follow the structure of the textbook; they are divided into three parts (Basic, Intermediate, and Advanced) along with the individual chapters. Such a user-friendly design enables easy access to all exercises and recordings. The WORKBOOK contains different types of written assignments, practice routines, play along sessions, keyboard realizations, play and sing tasks, and ear training drills; they are carefully designed to master the content of Jazz Theory: From Basic to Advanced Study. All the exercises and scores are downloadable as PDFs.

The choice of specific tasks in each chapter depends on the content of the individual chapters. For example, Chapter 13 includes various keyboard tasks and ear training drills, but contains no play along sessions; Chapter 10 features more play along tracks than any other types of exercise. The main objective of Chapter 10 of the book, for instance, is to put the content of Part One to practical use. You will quickly realize that to be successful at playing with the rhythm section (tracks 5–18), you will need a solid command of the modes in all 12 keys (Chapter 7). Since the primary goal of these play along sessions is to acquaint your ear with the sound of the 14 modes and to find that sound on your instrument, start by playing the most important notes from the mode (guide tones and beauty marks) and negotiate them in some kind of rhythmic fashion. Having established the connection between theoretical concepts (guide tones and beauty marks in this particular instance) and practice (the ability to effortlessly play them on your instrument), you will begin to listen to your own playing and to interact with the rhythm section. Next, start using the motifs from the book (Figure 10.10) and transpose them to 12 keys. With these motifs, focus on the techniques of motivic development (Chapter 10), select a single technique, and explore it in your playing. As you get more comfortable with handling one technique at a time, explore improvising with two (or more) techniques.

Finally, you are ready to compose your own motifs and use them in improvisation. As you see, tracks 5–18 (as well as other play along tracks) work just as well for advanced players as for beginners. The process described above illustrates how to use play along tracks; this process can be summarized as follows: (1) establish a connection between theory and practice, (2) practice on your instrument, (3) begin with the material that you can handle, (4) challenge yourself, and (5) be creative.





A measured approach to completing assignments works for the majority of exercises included in the WORKBOOK. Take, for instance, Exercise 3.3. The exercise includes seven four-bar progressions to be realized at the keyboard in C major and/or A minor. The basic objective for all playing exercises is to be able to perform a given task at a steady tempo and without breaks. Start at a comfortable tempo (♩=50) and play the progressions from Exercise 3.3 from beginning to end without interruption. Using a metronome is highly recommended. Gradually increase the speed of your performance to ♩=96. The instructions for this and other keyboard exercises include the dreaded phrase: “transpose to all 12 keys.” Playing in all 12 keys is an essential skill for the contemporary musician, yet learning to play in all keys is a long and arduous process. In Chapters 6, 12, 13, and 15, the “12 key” icon is used as a reminder to practice/perform the specific musical figures in all 12 keys. To facilitate this process, learn a progression in the original key. Once you master the progression in a single key and explore different positions/inversions of chords, start transposing it to two or three different keys. Practice the progressions in two or three keys and then start adding more keys to your practice routines. You will notice that once you work diligently through six different transpositions, the remaining ones will be quite easy to realize. To master the skill of playing in 12 keys, you need to be consistent, succumb to daily practice routines, and allow the passing of time to see the results.



In studying jazz, it is imperative to develop an impeccable ear capable of identifying complex chord formations and harmonic progressions. The WORKBOOK also features different types of ear training activities: rhythmic dictations, harmonic dictations, chord recognition, singing, set-class identification, etc. To access them, click on the corresponding icon. I recommend that you complete each ear training drill before proceeding to the next one, no matter how trivial that drill might seem. Without internalizing the sound of individual intervals/triads in Chapter 1 or four-part chords in Chapter 4, for instance, the ability to hear more complex five-part chords in Chapter 5 or upper-structure triads in Chapter 14 may prove challenging. Furthermore, when individual chords or the II–V–I progressions from Part One begin to form four-bar progressions in Chapter 13 or eight-bar phrase models in Chapter 21, the ability to identify individual formations is of utmost importance to make tonal sense out of complete harmonic progressions. Since certain tracks for ear training drills contain multiple intervals, harmonic formations, chord progressions, or set classes, I recommend starting each track at a different location to avoid memorizing the sequence of events.

Recordings

In addition to various written and ear training exercises in the WORKBOOK, the companion website also contains the recordings of musical figures from the book. The RECORDINGS section is also organized exactly as the textbook (three parts and individual chapters) and gives you immediate access to all audio files. By clicking on the figure, you will see the specific musical example and hear the recording. These recordings are quite useful when you are away from the keyboard (or have insufficient keyboard skills) and want to hear a particular musical illustration. By listening to these audio recordings you are mapping individual theoretical entities (chords, modes, progressions, scales, phrase modes, sets, etc.) with their sound and, thus, training and improving your ear.

Appendices/Auxiliaries

This section contains some useful material that complements the book. The Selected Discography (Appendix F) contains the list of recordings for standard tunes discussed in the book. For each tune, there are representative recordings that show how the different jazz artists from different eras appropriated these tunes into their repertoires and how different these interpretations are; this extraordinary interpretive diversity demonstrates the limitless potential of standard tunes. Listening to jazz goes hand in hand with learning how to improvise and how to find one's musical voice. Without exploring the rich canon of recorded jazz, one's quest for learning how to improvise might be deterred indefinitely. The Selected Discography and List of Solos to Transcribe in Appendix E (as well as the endnotes in the book) provide many valuable listening resources.

Finally, the companion website contains downloadable scores for ear training drills, extra scores for the Play Along DVD (convenient to use with your iPad on the music stand), an Answer Key for Written Exercises, and an Answer Key for Ear Training Drills (with a few exercises realized in full score so you can see what I played on the recording).

TO THE STUDENT



* * *



In Part One, the foundation of the entire pedagogical system is laid, each topic leading logically to the next. Therefore, it is imperative to study each chapter before proceeding to the next one. Use of the online WORKBOOK is strongly recommended; it contains numerous exercises to foster your understanding of various theoretical subjects. For optimal use of this resource read How To Use The Companion Website. For those already familiar with the basics or those who want to delve deeper into more advanced topics (Bebop, Pentatonics and Hexatonics, Phrase Models, Post-Tonal Jazz, etc.), start with a chapter that appeals to you. Each chapter, especially in Parts Two and Three, is a self-contained unit for you to explore. If you use this approach, first familiarize yourself with the terminology and various notational conventions discussed in Part One since they may be different from yours.

TO THE INSTRUCTOR



* * *



In Jazz Theory: From Basic to Advanced Study, I build on the existing terminology concerning chord notation and other analytical conventions. One of the main issues music theorists often grapple with is that of chord notation, a proverbial Tower of Babel in a world where notational idiosyncrasies run amok. To be fair, systems of chord notation are constantly evolving and, in spite of the best intentions, no syntactical uniformity exists that would satisfy everyone. As described in Chapter 3, each method of chord notation has its strengths and weaknesses. In notating chords in the book, I aim to be as consistent and lucid as possible. After discussing the subject with colleagues and reviewers, and trying out many systems with my students, I settled on the following symbols. Given the CMaj7(♯11) chord, for instance, the chord quality is indicated with a “Maj” suffix, the essential chord tone “7” is written as a regular size Arabic number, and a chromatic extension is placed in parentheses and written as a superscript number. The Cmin9(♭13) chord uses a superscript for the diatonic extension “major ninth” and places the chromatic extension in parentheses. Lead-sheet symbols employed in the book, then, provide a complete description of a chord's structure; they are easy to realize and show that essential chord tones are hierarchically more important than chordal extensions. Additionally, they are arranged according to their status and influence on the overall sound of the chord.

Although marred by its syntactical ambiguities in common-practice theory, the use of Roman numerals in Jazz Theory: From Basic to Advanced Study is reduced to four-part structures only, regardless of the actual pitch content of the chord. Roman numerals, then, represent the quality, functionality, scale-degree position, and the type of essential chord tones added to a triad. The following six basic symbols are encountered: Imaj7, I7, i7, , iø7, and i°7, representing major 7th, dominant 7th, and minor 7th, minor 7(≭5), half-6 diminished 7th, and diminished 7th chords, respectively. (Occasionally triads and I6 also occur.) In this notation, the suffix “maj” uses lower-case letters with the essential chord tones written as superscripts (and as a subscript in the case of ). Though Roman numerals require some expertise to realize in performance, they constitute excellent tools for transposing chord progressions to all 12 keys. Since Roman numerals represent essential four-part structures only, their interpretation and realization is predicated on a number of factors: melodic content, dissonance treatment, chromaticism, outer-voice counterpoint, voice leading, harmonic affects, phrase rhythm, and other issues discussed in this book.

THEORY IS A MEANS TO AN END



* * *



As stated earlier, the ultimate goal of Jazz Theory: From Basic to Advanced Study is to improve one's improvisational skills. In a sense, then, theoretical knowledge is a means to that end; for the jazz musician this is synonymous with being proficient at different styles of improvisation. To attain that goal, I discuss at length four contrasting styles of improvisation: blues, modal, bebop, and the “Tristano” school. As the most important musical form in jazz, the blues takes precedence with extensive coverage in Chapters 9 and 17. Modal improvisation is explained in Chapters 7, 8, 16, and 20. The techniques of bebop improvisation are discussed in Chapter 15 and applied to practical ends in Chapters 17–19. The “Tristano” school of improvisation is codified through the prism of Lennie Tristano's solo on “Line Up” analyzed in Chapter 26. In addition to these four improvisational traditions, Chapter 27 makes substantial inroads into a more experimental, yet highly organized, system of advanced harmony and improvisation. In this chapter, I attempt to establish an interdisciplinary connection between atonal music theory and jazz theory. It is my humble wish to see the ideas developed in Chapter 27 taking new roots and being advanced by other jazz scholars. The possibilities are truly endless and the door for new explorations is left wide open.

Witnessing a project of this magnitude taking shape has left me with a sense of accomplishment and also provides a wonderful opportunity for me to thank the many people without whom this book could not have been written. First and foremost, I would like to thank Douglas Lowry (Joan and Martin Messinger Dean Emeritus of the Eastman School of Music) and Jamal J. Rossi (Dean of the Eastman School of Music) for granting me a leave of absence in the spring of 2012, during which the majority of the book was written. Dean Lowry will be greatly missed by all who had the privilege of knowing him personally. Second, I would like to thank my colleagues in the Jazz Department at ESM: Harold Danko, Bill Dobbins, Jeff Campbell, Clay Jenkins, Rich Thompson, Dave Rivello, Bob Sneider, and Mark Kellogg, all of whom have been very supportive of the project and on whose expertise I could always count. My profoundest gratitude and heartfelt thank you go to my friend Matthew Brown for his guidance over the years and for the countless hours of stimulating conversations during which many of the concepts appearing in this book were generated. On that note, I would like to thank Robert Wason for his encouragements in pursuing the more scholarly aspects of jazz music theory.

I am indebted to many years of wonderful students at the Eastman School of Music, but perhaps particularly to: David Baron, Ben Bishop, Evan Burrus, Greg Chaco, Dave Chisholm, Mike Craig, Gabe Condon, Alistair Duncan, Jacob Dupre, Wendy Eisenberg, Kate Ernst, Sam Farley, Austin Gross, Shoghi Hayes, Ethan Helm, Kevin McDonald, Jeff McLeod, Brendan Lanighan, Emiliano Lasansky, Stefan Love, Paulo Perfeito, Marcelo Pinto, Levi Saelua, Jeremy Siskind, Karl Stabnau, Alexa Tarantino, Nikola Tomic, Nick Weiser, and Chris Ziemba. Special thanks go out to Amy Kintner for her exceptional and meticulous work editing the initial draft of the book.

I would like to thank all the amazing musicians with whom I had the privilege to record all the musical examples, play along tracks, and ear training drills: Jeff Campbell (bass), Rich Thompson (drums), Gabe Condon (guitar), and Karl Stabnau (saxophones).

PITCH




* * *



Pitch refers to the relative highness or lowness of musical sounds. Figure 1.1 illustrates the placement of pitches on the keyboard with the lowest notes on the left and the highest notes on the right.





FIGURE 1.1 Keyboard—Pitch Layout


To label pitches, we use the letters from the alphabet—A, B, C, D, E, F, and G—to denote the white notes and accidentals (sharps or flats) to denote the black notes. Each note on the keyboard has a distinct sound; notes that have the same letter name sound similar in spite of their location on the keyboard. Theorists refer to this idea as octave equivalence. The distance from C4 to C5 includes eight pitches (counting C4 and C5) and is therefore known as an octave. Integers 1 through 8 following the letter names indicate eight different registers or specific pitch locations characterized by their sound. With higher integers we experience higher sounding pitches, and with lower integers we experience lower sounding pitches. Labeling black notes is more complicated because they can be described in two ways. For example, the black note between C and D can be labeled either as C♯ or D♭. Since C♯ and D♭ sound the same on the piano, theorists often refer to them as being enharmonically equivalent.

Music is notated on a staff that consists of five lines (the first line is at the bottom of the staff) and four spaces (the first space is located between the first and the second line of the staff). The addition of extra lines called ledger lines (up to five) at the bottom or top extends the staff and allows for the notation of pitches that lie outside the boundaries of the five-line staff. A clef written at the beginning of the staff indicates the location of pitches, which are notated with a system of notes. Although there are many different clefs, only treble and bass clefs will be used in this book.1 The grand staff combines two staves joined by a brace, with the top stave using the treble clef and the bottom stave using the bass clef. Figure 1.2 illustrates the notation of pitches from A0 to C8 on the grand staff.

The octaves, C1–C2, C2–C3, etc., create a specific pattern of whole steps and half steps. A half step (or semitone) is the shortest possible distance between two keys (or notes). For instance, the distance between E4 and F4 or B4–C5 is a half step. A whole step (or whole tone) combines two half steps and represents the distance between two keys with a single key between them. For instance, the distance between C4 and D4, D4–E4, F4–G4, G4–A4, or A4–B4, is a whole step because there is a single black note between these notes.





FIGURE 1.2 Grand Staff—Notation of Pitches





MAJOR SCALES




* * *



The collection of notes from C4 to C5, shown in Figure 1.3, represents a specific pattern of whole steps and half steps known as a major scale.





FIGURE 1.3 Major Scale


The major scale has five whole steps, beginning between scale degree one (written as ) and , –, –, –, and –, and two half steps between –, and –(). This arrangement of pitches represents one type of diatonic scale. The other diatonic scales also contain five whole steps and two half steps but those intervals between different scale degrees occur at a different location within the scale. For instance, the spans F4–F5 or G4–G5 filled in with white keys only (G4–A4–B4–C5–D5–E5–F5), shown in Figure 1.4, contain five whole tones and two semitones, yet their placement is different than it is in the C major scale. In order to duplicate the locations of whole tones and semitones as they occur within the C major scale, accidentals—a sharp sign (♯) and a flat sign (♭)— have to be implemented. The sharp added to F5 (in the G4–G5 octave) raises the sound of F5 by a semitone and becomes F♯5. The flat added to B4 (in the F4–F5 octave) lowers the sound of B4 by a semitone and becomes B♭4. With these added accidentals, the arrangement of whole tones and semitones occurring in the C major scale can be duplicated. These collections are labeled using their opening pitches: G major and F major, respectively.

There are 12 possible major scales, one for each white and black note (C major, C♯/D♭ major, D major, D♯/E♭ major, E major, F major, F♯/G♭ major, G major, G♯/A♭ major, A major, A♯/B♭ major, B major).





FIGURE 1.4 G major and F major





KEY SIGNATURES




* * *



Another method of representing major scales is to use key signatures written to the right of the clef. Since there are 12 distinct major scales, there will be 12 corresponding key signatures. For instance, the G major scale that we saw in Figure 1.4 has one sharp, F♯. The key signature places that sharp at the beginning of the staff immediately after the clef. Just as the G major scale has one sharp (F♯), so D major has two (F♯, C♯), A major has three (F♯, C♯, G♯), E major has four (F♯, C♯, G♯, D♯), B major has five (F♯, C♯, G♯, D♯, A♯), F♯ major has six (F♯, C♯, G♯, D♯, A♯, E♯), and C♯ major has seven (F♯, C♯, G♯, D♯, A♯, E♯, B♯). Similarly, whereas the F major scale has one flat (B♭), B♭ major has two flats (B♭, E♭), E♭ major has three (B♭, E♭, A♭), A♭ major has four (B♭, E♭, A♭, D♭), D♭ major has five (B♭, E♭, A♭, D♭, G♭), and G♭ major has six (B♭, E♭, A♭, D♭, G♭, C♭). In the case of F♯ and G♭ and C♯ and D♭, the key signatures are often spelled enharmonically. This is shown in Figure 1.5 by the arrows.





FIGURE 1.5 Key Signatures—Major Scales





MINOR SCALES




* * *



Figure 1.6 illustrates the distribution of whole tones and semitones within the A3–A4 octave that forms a minor scale.





FIGURE 1.6 Minor Scale


The two semitones are located between – and –, and the five whole tones between –, –, –, –, and –(). Similar to C major, the A minor scale uses only the white keys of the keyboard and has no key signature. In addition to the so-called natural version of minor, there are two additional “shades” of minor: harmonic and melodic. The three versions of minor are illustrated in Figure 1.7 with the melodic minor shown in the ascending and descending form.





FIGURE 1.7 “Shades” of Minor


The harmonic form of minor raises of the natural minor. The melodic form of minor raises and of the ascending natural minor scale. The presence of ♯ in the harmonic and melodic versions creates a characteristic half-step motion from ♯ to (), which is analogous to the half step between –() in the major key. The use of a natural sign (♮) in the descending form of the melodic minor cancels out the previously attached accidentals to F4 and G4. It is important to stress that the harmonic and melodic versions of minor are not independent scalar collections; rather, they represent variants or “shades” of the minor scale. The use of key signatures always corresponds to the natural minor and does cover the necessary accidentals occurring in the harmonic and melodic forms. Figure 1.8 illustrates the pitch structure of C major and A minor along with the scale degree names.

As there are 12 major keys, there are also 12 minor keys, shown in Figure 1.9.

Whereas the E minor scale has one sharp (F♯), so B minor has two (F♯, C♯), F♯ minor has three (F♯, C♯, G♯), C♯ minor has four (F♯, C♯, G♯, D♯), G♯ minor has five (F♯, C♯, G♯, D♯, A♯), and D♯ minor has six (F♯, C♯, G♯, D♯, A♯, E♯). And, the D minor scale has one flat (B♭), G minor has two flats (B♭, E♭), C minor has three (B♭, E♭, A♭), F minor has four (B♭, E♭, A♭, D♭), B♭ minor has five (B♭, E♭, A♭, D♭, G♭), E♭ minor has six (B♭, E♭, A♭, D♭, G♭, C♭), and A♭ minor has seven (B♭, E♭, A♭, D♭, G♭, C♭, F♭). In the case of G♯ and A♭ and D♯ and E♭, the key signatures are often spelled enharmonically. This is shown in Figure 1.9 by the arrows. We refer to the pair of major and minor keys that share the same number of key signatures as relative keys. For example, G major and E minor both have one sharp (F♯), and A♭ major and F minor have four flats (B♭, E♭, A♭, D♭).

RHYTHM




* * *



Music is notated with various rhythmic symbols that are proportionally related to one another. Figure 1.10 summarizes the basics of rhythmic notation.

The note values and the corresponding rests are divisible by two: a whole note contains two half notes, a half note contains two quarter notes, etc. A dot, written on a space between staff lines, extends the duration of the note, rest, or dot that precedes it by half of its value. A dotted half note extends the duration of the half note by one quarter note and contains three quarter notes. A tie connects two or more notes at the same pitch level and creates a new duration equal to their sum. Beams are horizontal lines that connect multiple 8ths, 16ths, 32nds, 64ths or any combination of them. In addition to the division of note values by twos, notes can also be divided by threes creating a triplet, fives creating a quintuplet, and sevens creating a septuplet.





FIGURE 1.10 Basics of Rhythmic Notation





METER AND TIME SIGNATURES




* * *



Note values do not represent a fixed rhythmic duration until they are placed in measures separated with bar lines, and associated with a specific beat value. Beats are grouped in units of two, three, four (and others) and stay constant throughout a musical passage. A recurrent pattern of accented (strong) and unaccented (weak) beats is known as the meter. The hierarchy between accented and unaccented beats is essential to establish meter. A piece of music is said to be in duple meter, if the pattern of accented beats recurs every two beats (| strong beat—weak beat |); in triple meter, every three beats (| s–w–w |); and in quadruple meter, every four beats (with an additional stress on beat 3, as in: | s–w–s–w |). In order to specify the exact pattern of beats within the measure (i.e. meter), the time signature must be used. Time signatures can be classified into three types— simple, compound, and irregular—and are notated by two integers. In simple time signatures, the top integer indicates the number of beats in the measure and the bottom integer indicates the underlying beat value. In compound time signatures, the top integer indicates the number of beat subdivisions in the measure and the bottom integer indicates the subdivision value. In irregular time signatures, the top integer refers to the number of beats in the measure and the bottom integer to the beat value. Simple and irregular time signatures do not indicate the number/value of the subdivisions; compound time signatures do not show the number/value of beats. Figure 1.11 provides a summary of the aforementioned concepts and terms.





Notating Rhythm


On the score, rhythmic groupings should clearly delineate the underlying pattern of beats. In addition to representing the meter, the recurrence of these patterns also facilitates the reproduction of a song during performance. Figure 1.12 illustrates an incorrectly notated rhythm and its corrected version. The corrected version has clearly demarcated beats: this renders the rhythm easier to perform and the meter easier to perceive. More challenging rhythms may be accurately represented with the aid of different rhythmic groupings, ties, and dots.





FIGURE 1.11 Meter, Time Signatures, Notating Rhythm





FIGURE 1.12 Incorrectly and Correctly Notated Rhythms





INTERVALS




* * *



An interval is the distance between two musical pitches. A melodic interval occurs between two adjacent notes and a harmonic interval occurs between two simultaneously sounding notes. There are many different methods of labeling intervals, some of which will be detailed in Chapter 27. Generic names refer to the number of letter names between the two notes. For instance, the interval from C4 to G4 is a fifth because the span between C4 and G4 contains five letter names (C–D–E–F–G); the interval from D4 to C5 is a seventh, etc. Generic interval names, however, do not indicate the quality or the exact size of the interval. To express the quality of intervals, we count the number of half steps between the two notes. Figure 1.13 illustrates eight diatonic intervals built on of the C major scale.

These intervals are called diatonic because they are derived from the pitches of the C major scale. Intervals derived from the pitches of other major or minor scales are also diatonic in the context of the respective keys. The interval from to is called a major second and contains two half steps; the interval from to is a major sixth and contains nine half steps. Each of these intervals can be made smaller or larger by altering one or two of their pitches by a half step. If these alterations occur in the context of C major, the resulting intervals are chromatic because they contain pitches that are foreign to the key of C major. Figure 1.14 shows chromatic alterations of intervals from Figure 1.13 and their full names.





FIGURE 1.13 Diatonic Intervals


To describe the quality of intervals, the following qualifiers are used: perfect (P), major (M), minor (m), diminished (D), and augmented (A).2 In labeling intervals, first count the number of letter names between the two notes (including the first note) and, then, count the number of semitones between them. For instance, the interval from C♯4 to A4 is a minor 6th because there are six letter names between C♯4 and A4 (C–D–E–F–G–A) and eight half steps. But the interval from D♭4 to A4 is an augmented 5th because there are five letter names between D♭4 and A4 (D–E–F–G–A) and eight half steps. An interval that exceeds the span of an octave is known as a compound interval. For instance, 9ths, 11ths, and 13ths are examples of compound intervals.





FIGURE 1.14 Diatonic and Chromatic Intervals





INVERSION OF INTERVALS




* * *



In order to invert a harmonic interval, the top note is placed below the bottom note or vice versa. For instance, the interval C–G (a perfect 5th) inverts to G–C (a perfect 4th). When counting the number of semitones in both intervals, 7 and 5, respectively, their sum equals 12. This indicates the number of semitones within an octave. The same is true of other inversionally related intervals. These are illustrated in Figure 1.15. The integers above the score indicate the number of semitones.





FIGURE 1.15 Inversions of Intervals





TRIADS




* * *



A triad is the combination of three simultaneously sounding pitches. Tonal music shows a preference for tertian sonorities—called chords—which are built of consecutive major, minor, diminished or augmented thirds. The four triads—major, minor, diminished, and augmented—explore different combinations of major and minor thirds (see Figure 1.16). Note that the tertian nature of triads is also reflected in their note spelling.





FIGURE 1.16 Basic Triads





INVERSION OF TRIADS




* * *



Figure 1.16 demonstrates complete triads in root position. In such cases, the root appears at the bottom, the third in the middle, and the fifth on top. To further explore the sound of triads, their notes can be rotated by transferring the bottom note up an octave. Since there are three different notes in the triad, the bottom note can be rotated twice before returning to the original position. These rotations are known as inversions. In the case of triads, there are two inversions: first and second. Figure 1.17 illustrates four types of triad: major, minor, diminished, and augmented in root position, first and second inversions.

The augmented triad partitions the octave into three equal parts. Each note of the augmented triad can potentially function as the root of a new augmented chord. The augmented triad is a type of chromatic formation because it contains a non-diatonic pitch, ♯, which is foreign to any major or minor key. Because of its symmetrical properties, each note of the augmented triad can potentially function as the root of a new chord (C+, E+, or A♭+ in Figure 1.17).





FIGURE 1.17 Basic Triads and Inversions





SUSPENDED TRIAD




* * *



In addition to the four triads shown in Figure 1.16, there are other possible combinations of three notes, such as the suspended (sus) triad shown in Figure 1.18. It is a sonority that breaks away from the tertian organization of notes and constitutes an important formation in jazz.





FIGURE 1.18 Suspended Triad


NOTES



* * *



1. The treble clef or violin clef is also known as the G-clef and the spiral of the lower part indicates the position of G4. The bass clef, also known as the F-clef, indicates the position of F3. In addition to these two clefs, there are various types of the C-clef of which the soprano, alto, and tenor are mostly used. The C-clefs indicate the position of the middle C—C4.

2. There are also double-diminished and double-augmented intervals; however these will not be discussed in this book.

GENERAL CHARACTERISTICS




* * *



It is not by chance that this study of jazz theory begins with the discussion of rhythm. Most jazz musicians will probably agree that having a good sense of time is key to successful improvisation and to overall musicianship. Great jazz artists have always understood the importance of rhythm and time; this comes through as an individual sense of swing on numerous recordings. Count Basie, for instance, could play four simple quarter notes and make them swing so hard that the entire band would immediately follow his lead and play with the same energy and dedication.1 The most effective way to learn about jazz rhythm is to listen and imitate the rhythm of great jazz artists. Listening to music is an important part of our musical development. It allows us to focus on different aspects of the musical performance, such as form, instrumentation, orchestration, rhythm, time, melodic devices, harmonic vocabulary, style, innovations, interaction, creativity, historical backgrounds, or tradition.





SYNCOPATION




* * *



Figure 2.1 illustrates the distribution of metric accents within a 4/4 measure.





FIGURE 2.1 Metric Accents in 4/4


Beats 1 and 3 in 4/4 time are hierarchically more important that beats 2 and 4. The former are known as strong beats and receive strong metric accents. Beats 2 and 4 are called weak beats and are hierarchically subordinate to beats 1 and 3. One of the characteristics of jazz rhythm is a shift of accents from 1 and 3 to 2 and 4. These dynamic (or phenomenal) accents create a rich and compelling dialog with the metrical accent on beat 1. By placing the dynamic accents on beats 2 and 4, jazz gets its own rhythmic identity. In addition, these accents help to create a characteristic disagreement between rhythm and meter. In jazz, rhythm seems to work against the underlying meter and that seeming disagreement influences the perception of time. The most immediate consequence of such a disagreement is the effect of syncopation; syncopation enhances the excitement of the music by distributing rhythmic figures and accents on unexpected locations within the measure. It also creates a variety of rhythmic conflicts that interact with the flow of regularly occurring metrical or phenomenal accents. Figure 2.2 illustrates a melodic line with a highly syncopated rhythmic design.





FIGURE 2.2 Syncopated Melody: “Moose the Mooche,” mm. 17–24





SWING




* * *



The term “swing” has multiple meanings and associations. Sometimes it refers to a specific musical style from the 1930s called Swing. It may also refer to a performance practice tradition or a specific rhythmic attribute attached to the quality of 8th notes. The term swing 8th notes is used to indicate 8th notes that are performed unevenly with an overall rolling (swinging) time feel. Because the exact notation of swing 8th notes is neither possible nor very practical, regular 8th notes will be used with the indication “swing” written in the top left corner of the score to denote swing 8th notes.





PRACTICING RHYTHM




* * *



Not only is playing with a good sense of rhythm and time essential to performance, but it is also crucial to successful practicing. When practicing improvisation, a variety of idiomatic rhythmic figures should be used. These should be played with rhythmic integrity, convincing phrasing, and good articulation. Figure 2.3 provides a selection of one-, two-, four-, and eight-bar phrases with idiomatic jazz rhythms that can be implemented in daily practice.

In notating 4/4 time, remember to keep beat 3 “visible”; avoid rhythmic groupings that obscure or de-emphasize beat 3. Figure 2.4 illustrates an incorrectly notated rhythm and its corrected version.

Rhythmic integrity relates to the way swing 8th notes are performed and placed within the beat. Broadly speaking, continuous swing 8ths are played as if notated as triplet 8ths. The first two triplets are tied (to become a quarter note) and the third one receives a slight dynamic accent. Figure 2.5 demonstrates this approximate notation of swing 8th notes.





Placement of Swing 8ths


Another important consideration regarding the quality of swing 8th notes relates to their placement within the beat. Swing 8ths can be placed in three different locations: behind the beat, in the middle of the beat, and in front of the beat. There is a huge rhetorical and perceptual difference between these locations. Their exact placement depends, in large part, on the overall tempo of the performance and the rhythmic tendencies of different jazz artists. Slow and medium-slow tempi tend to use more “behind the beat” note placements, medium-up and faster tempi lend themselves to a “middle of the beat” or “in front of the beat” treatment. Certain jazz artists show such a strong propensity toward the particular note placement, that their names have been identified with the specific performance practice technique. For instance, the great tenor saxophone player, Ben Webster, made wonderful use of “behind the beat” playing. His many recordings convey a relaxed, laid-back, and highly original time feel.2 The guitar player active in the late 1930s, Charlie Christian, on the other hand, preferred to play in the “middle of the beat,” and his constant swing 8th notes were perfectly located in the center of the beat.3 A jazz icon from the Post-Bop Era, the alto saxophonist Cannonball Adderley, preferred his swing 8th notes slightly “in front of the beat” to energize the music with rhythmic excitement and vitality.4





Phrasing


The use of dynamics, legato, and especially articulation can substantially improve the overall presentation of melodic lines. Generally, the use of dynamics should roughly follow the contour of the melodic lines. Rising lines are typically played with a slight crescendo and descending lines with a slight diminuendo. Additionally, melodic lines should be played almost legato with barely perceptible note detachment. Carefully distributed articulations (dynamic accents, staccato, tenuto, marcato, etc.) are also an essential component of phrasing. When listening to the phrasing of the great players Wynton Kelly, Kenny Dorham, Hank Mobley, Clifford Brown, Tommy Flanagan, Lee Morgan, Sonny Rollins, Sonny Stitt, Dexter Gordon, Woody Shaw, Grant Green, Joe Henderson, Freddie Hubbard, Jackie McLean, Blue Mitchell, Barry Harris, and others, notice that their excellent use of articulation not only creates a strong sense of swing, but it also defines their individual styles of improvisation.5 The highest note within a phrase typically receives a stronger accent regardless of its position within the measure. Also, upbeats tend to be more accentuated within a phrase than downbeats. There are, however, many exceptions to these rules that will be addressed as the book unfolds.





FIGURE 2.3 One-, Two-, Four-, and Eight-Bar Rhythmic Ideas





FIGURE 2.4 “Visible” Beat 3




FIGURE 2.5 Swing 8th Notes





Playing with a Metronome


As we assemble the aforementioned suggestions and put them to practical ends, the use a metronome on “2 and 4” can vastly improve the quality of our swing 8th notes and solidify their placement within the measure. Playing with a rhythm section is a privilege that most jazz musicians cherish. More often than not, however, we practice alone and the metronome might be the only available recourse to check if our time and rhythm are correct. Set the metronome to 66 and make each click count as a half note on beats 2 and 4.

FUNCTIONAL TONALITY




* * *



Chords and lines represent two interconnected musical forces that are capable of producing an amazing variety of linear and harmonic patterns. In tonal jazz, the behavior of these patterns is predictable, hierarchical, and systemic. In a certain sense, harmonic function can be defined as a contextual feature that can be attributed to a chord, a family of chords, harmonic progressions, or even to complete melodic phrases. These features are unique for each of the following functions: the tonic, the predominant, and the dominant. The interaction between these three creates a system of functional tonality, which undergirds the structure of tonal jazz and common-practice music.

Functional tonality is a hierarchical system wherein the predominant and the dominant are ultimately related to and controlled by the tonic. The tonic is thus at the center of this hierarchical system. The uniqueness of each harmonic function is defined by universal and well-tested characteristics of functional tonality. The tonic is synonymous with stability, rest, and the cessation of harmonic motion. The predominant generates harmonic motion by taking the music away from the tonic and leading it toward the dominant. The dominant is an antithesis of the tonic in every conceivable way: it is highly unstable, represents chords on the move, accumulates harmonic tension, and does not rest until it reaches a local or structural tonic. These very different behavioral patterns remain constant across the entirety of the tonal system in which jazz forms a distinctive musical language with its own harmonic grammar and melodic syntax. As will be demonstrated time and time again, functional tonality in jazz has different properties than that of common-practice classical music. These properties are represented by a unique set of rules dictating the unfolding of harmonic function, voice-leading conventions, and the overall behavior of chord tones and chordal extensions.





TRIADS IN MAJOR KEYS




* * *



Figure 3.1 illustrates the structure of the tonic, subdominant, and dominant triads in the key of C major.

In all major keys, the tonic, the subdominant, and the dominant are major.

In addition to the tonic, subdominant, and dominant triads, the tonality system includes triads built on other scale degrees as well. A triad built on is called the supertonic; on , the mediant; on , the submediant; and, on , the leading tone. Figure 3.2 illustrates triads built on each scale degree in C major.





FIGURE 3.1 Tonic—Subdominant—Dominant


The use of a diminished triad on expands the quality of chords occurring in a major key to three distinct types: major, minor, and diminished.





FIGURE 3.2 Triads in Major Key





TRIADS IN MINOR KEYS




* * *



Figures 3.3–3.5 show the distribution of triads in the three “shades” of minor: natural, harmonic, and melodic.





FIGURE 3.3 Triads in Natural Minor





FIGURE 3.4 Triads in Harmonic Minor





FIGURE 3.5 Triads in Melodic Minor


The triads in natural minor use the same names for the scale degrees as they do in the major key, with the exception of the triad on , which is called the subtonic.

There are two diminished triads built on and ♯ and one augmented triad on . The scale degree ♯ is called the leading tone.

The scale degree ♯ is called the raised submediant. In indicating the scale degrees and in the melodic minor, the ♯ and ♯ labels are used, respectively.

The tonic, predominant, and dominant functions contain a collection of similarly functioning chords, including (but not limited to) chords built on scale degrees with which these functions are typically associated. For instance, the chords built on and are known as subdominant and supertonic, respectively, and they share the predominant function; the chords built on and share the dominant function, etc.





NOTATIONAL CONVENTIONS




* * *



Figure 3.6 illustrates the structure of four triads and their inversions labeled with three sets of notational symbols: traditional lead-sheet notation above the staff, and Roman numerals and function symbols below the staff. Since we will use them interchangeably throughout the book, let us make some general observations about their usefulness in theory and practice. Each of these notational conventions has unique advantages, but also some obvious shortcomings.





FIGURE 3.6 Notational Conventions





Lead-Sheet Notation


Lead-sheet notation, also known as popular-music notation, is by far the most widespread notational convention used by jazz musicians. It comes in a variety of forms that arise from its murky origins and subsequent vague implementations. There are many alternate notational systems in use, which for better or worse every jazz musician needs to get familiar with for purely practical, “bandstand” reasons. Here, we will only use chord symbols that are commonly found in published and respected fake books. Lead-sheet notation is very specific in showing what the chord is: it indicates the letter name, the exact number and types of extensions occurring within a chord, chordal inversions, or complex polychordal formations. A chord symbol, then, provides a quick insight into the chord’s pitch content. As such, it can be easily transmitted into a voicing that captures the essence of that symbol. The downside of this labeling is the lack of contextual considerations, especially in regard to the underlying tonality. As a tonally “uninterpreted” notation, we are not quite sure, for instance, how chords relate to one another, how their behavior conveys the underlying tonality, and what the overall tonal logic of different chord successions may be.

In this book, upper-case letter names will be used to indicate major-type chords. For minor-type chords a “min” extension following an upper-case letter name will be used. The lead-sheet symbols from Figure 3.6 also employ slash notation; this specifies a chord type with the lowest sounding pitch separated by a diagonal slash. An upper-case letter name to the right of the diagonal indicates the chordal root. The letter name to the left of the diagonal shows a specific chord type.





Roman Numerals


Roman numerals are context-sensitive and indicate the exact position of chords with respect to the underlying tonic. This style of notation is very powerful in explaining the tonal behavior of chords and is mostly used in analysis. Some jazz musicians, however, have found a useful niche for this type of notation. By translating the lead-sheet notation of a standard tune into Roman numerals, jazz musicians can easily transpose and learn that tune in all 12 keys. But Roman numerals, too, have their disadvantages. Problems with this style of notation arise when a tune modulates away from the underlying tonic or frequently tonicizes new key areas. With the addition of Arabic numbers borrowed from the figured-bass tradition, Roman numerals are capable of expressing complex five-, six-, or seven-part chords. When using Roman numerals, however, complex five-, six-, or seven-part formations will be translated to their essential four-part framework. For instance, F7(♭13) in the key of C major will be simply notated as IV7.

The addition of available extensions to chords is a matter of personal preference and reflects the underlying context in which specific chords occur. The practice of adding extensions or reinterpreting chords is similar to that of interpreting unfigured basses from the Baroque period. There are, however, many musical situations where more detail is desired, such as when a composer or arranger wants a specific sound or voicing. In those types of situation, a chord symbol might include more detailed information about chordal extensions, note omissions, or even a specific arrangement of notes. These chord symbols typically stand out among other, more conventionally written chords. Given the very different notation systems being used, we can start thinking more rigorously about our own notational choices.

In Figure 3.6, the tonic chord in root position is notated with a “” symbol. In practice, however, a “I” will be used without the Arabic numbers because they are assumed. Also, in notating a chord in first inversion, the Roman numeral representation has already been simplified: instead of a complete “” symbol, the “I6” symbol was used. Roman numerals might also include “♮,” “♯” and “♭.” Written in front of the Roman numeral, these accidentals indicate chromatic scale degrees in relation to the underlying key. To notate major chords, upper-case Roman numerals will be implemented, and to notate minor chords, lower-case Roman numerals will be used. A diminished triad will take a lowercase Roman numeral with a small raised circle, vii°; an augmented triad will use an uppercase Roman numeral with a small plus sign, III+.





Function Symbols


The function symbol notation is the least used notational system in jazz. As the name suggests, this notation specifies the harmonic function of individual chords and even complete chord progressions. It has the potential of being useful to notate specific behaviors of chords that may not—at least, not on the surface level—indicate that they belong to a particular functional family of chords. As such, function symbols enable the perception of harmonic progressions from a more structural perspective. Function symbols indicate neither the architecture nor the specific scale degrees of chords. This style of notation is more conceptual than it is representative of a specific surface event. The terms surface level and structural level are used to describe musical events and the degree of their importance. “Structural” events occur beneath the musical “surface” and are responsible for the overall tonal, harmonic, and melodic forces controlling the piece. Function symbols use three labels: T for tonic-type chords, PD for predominant-type chords, and D for dominant-type chords.





FUNCTIONAL FAMILIES




* * *



When comparing triads built on different scale degrees in Figures 3.3–3.5, notice that some of them share the same harmonic function. Some triads can even have two different functional symbols.





Major Key


A functional family combines chords built on different scale degrees that share the same harmonic function and voice-leading behaviors. Chords within each family are organized hierarchically according to their degree of similarity and dependency on the tonic, subdominant, and dominant triads. Figure 3.7 illustrates three families of similarly functioning chords in major.





FIGURE 3.7 Functional Families in Major


Broadly speaking, functional families illustrate possible successions of chords within a tonal family and between chords of different families. The succession of T–PD–D–T, illustrated by arrows in Figure 3.7, is the most fundamental and demonstrates how chords can be combined to project a sense of tonality. This succession of harmonic functions highlights the cycle of fifths, a pattern that constitutes an essential trademark of common-practice tonality. Descending fifth motions are what we tend to hear as forward moving—in the sense of time or momentum—because of their drive toward tonic resolution. Any succession of chords is also dependent on its relationship to the metric and rhythmic properties of the phrase, as well as on the chord’s ultimate move toward a cadence. The terms “cadence” or “cadential closure” signify an important tonal event that confirms the underlying tonic (or new key) by means of a V–I progression. Figure 3.8 demonstrates the distribution of harmonic functions within a I–vi–ii–V–I progression. Scale degrees written above the staff indicate the melodic content of the soprano voice.

The chords I and vi are derived from the tonic family and, in certain situations, can be used as substitutes for one another. In the context of the progression from Figure 3.8, it makes sense to hear the submediant chord as a transitional space between I and ii or as tonic prolongation. Having prolonged or expanded the tonic, the vi chord moves by a fifth down to the predominant ii, which then proceeds by another fifth to the dominant on V. The progression ends with a V–I cadential confirmation of the tonic featuring another descending fifth motion. In this early exposition of harmonic progressions, we cannot ignore other important factors that contribute to the concept of tonality, such as metric placements and duration of chords. The vi chord occurs on beat 3 of m. 2 and lasts for 2 beats. The predominant ii occupies m. 3 and the ii–V cadential preparation of the tonic occurs in m. 4. The V–I cadential confirmation occurs over the bar lines in mm. 4–5; this progression produces forward motion and illustrates the hierarchical relationship between V and I. The tonic provides the resolution of harmonic tension and its metric placement on beat 1 in m. 5 highlights its structural and tonal significance.





FIGURE 3.8 Tonal Progression in Major





Minor Key


Figure 3.9 illustrates three functional families in the minor key and demonstrates the common-tone retention between chords within each family. The predominant and dominant families combine chords from the three “shades” of minor.

Functional families in the minor key show considerable triadic variety and are much more intricate than their major counterparts. Each family includes different types of triad, with the potential for complex functional relationships.

Figure 3.10 illustrates the succession of harmonic function in a slightly more advanced progression in 3/4.

The mediant chord, III+, occurring on beat 3, is a transitional space between i and VI. Even though the III+ can also function as a dominant, it functions as a tonic expansion in the context of this progression. Motion to the dominant in the second chord would have created a retrogression of harmonic function: dominant to predominant. The third chord of the progression, the submediant also has two functional assignments: tonic and predominant. Based on the surrounding context though, especially the forthcoming iv, the VI can be interpreted as belonging to the predominant family of chords. The predominant ii° in m. 3 forms a cadential gesture with the dominant that then resolves deceptively to the VI. Given the two functional assignments of VI, it functions as a tonic in the context of this progression.





FIGURE 3.9 Functional Families in Minor





FIGURE 3.10 Tonal Progression in Minor


The analytical readings of Figures 3.8 and 3.10 use the word “context” to describe the functional behavior of chords. The surrounding harmonic context in which chords occur determines the analytical interpretation of these chords. As stated earlier, chords from each functional family create certain expectations and display behavioral patterns that largely depend on their metric position and duration within harmonic progressions. In addition, each functional family is defined by a specific musical affect: the tonic with stability, the predominant with forward motion, and the dominant with tension seeking resolution.





VOICE-LEADING PRINCIPLES




* * *



Broadly speaking, voice leading controls the interaction between chords and lines within harmonic progressions. The principles of voice leading encompass several general topics, such as the role of outer-voice counterpoint, the types of melodic motion, the retention of common tones, the treatment of dissonances, and others that will be discussed throughout the book.

At the surface level, jazz voice-leading conventions seem more relaxed than they are in common-practice music. After all, jazz musicians use forbidden parallel perfect fifths and octaves, move all the voices in the same direction, and tolerate voice crossings of different sorts. The rules of jazz voice leading are different because the syntax of jazz is largely incompatible with common-practice classical or other types of music. These differences do not mean, however, that the rules of jazz voice leading are any less strict. When jazz musicians think about dissonance treatment or highlight a linear approach to harmony as opposed to a vertical one, they rely just as much on well-defined rules of voice leading as do composers of common-practice music. The conventions of jazz voice leading depend greatly on the soprano and bass, so-called outer-voice counterpoint. In general, proper intervallic relationship between the outer voices guarantees a successful realization of harmonic progressions and influences the behavior of inner melodic lines. What characteristics, then, should underlie the design of outer-voice counterpoint? First, the outer-voice counterpoint should form a harmonically independent, two-voice framework. This means that the outer voices should delineate the underlying harmony without any help from inner voices. Second, the outer voices should be melodically interesting. This characteristic relates mostly to the design of the highest (or soprano) line, but in more complex progressions, it might also affect the design of the bass line. Third, outer-voice counterpoint should prioritize the use of contrary motion, though other types of melodic motion, such as oblique, similar, and parallel, are also possible.

Figure 3.11 illustrates four types of melodic motion.





FIGURE 3.11 Types of Melodic Motion


Parallel motion involves two voices moving in the same direction using the same generic interval. As far as its aesthetic value in jazz, too much parallelism might be monotonous, although in certain harmonic situations and musical styles—modal jazz in particular—this type of melodic motion is highly desirable. Similar motion occurs when two voices move in the same direction with different intervals between the notes. Oblique motion occurs when one voice ascends or descends while the other is standing still, but they are still moving homophonically. One of the most common variants of oblique motion involves pedal points; here, the harmonic motion often seems to be suspended and may be reduced to a single underlying harmony, often the dominant. Although less common, oblique motion might also feature a soprano (or inner) pedal point where a stationary soprano (or inner) voice supports a melodically active bass. The most effective type of melodic motion is contrary motion, in which two voices move in opposite directions and employ different intervals.





BASIC KEYBOARD APPLICATIONS




* * *



We will now cover some basic voice-leading principles that should prepare us for the exercises in the online Workbook. Figure 3.12 illustrates an eight-bar harmonic progression with triads and triadic inversions only. Based on the progression, we will highlight some common voice-leading principles. In order to do so, let us make some analytical observations about the progression itself. In mm. 3–4, the progression modulates to the key of A minor. Boxes around Roman numerals indicate a pivot area, containing diatonic chords simultaneously functioning in the key of C major and A minor. These pivot chords provide an effective link between these two key areas. A pivot chord is a chord that is common to two different keys; its dual functionality allows for a smooth transition from one key to the other. More specifically, a diatonic pivot chord contains diatonic pitches and connects closely related keys. A chromatic pivot chord admits pitch alterations and connects closely, as well as distantly, related key areas.





FIGURE 3.12 Keyboard Realization and Analysis


Keyboard style texture, like that represented in Figure 3.12, uses three notes in the right hand (R.H.) and a single note in the left hand (L.H.). With triad formations like this, we need to consider which note in a chord to double. As a general principle, in root-position and first-inversion triads we double the root (with the exception of root position vi in the V–vi progression; see mm. 2–3 in Figure 3.12). In second-inversion triads, we can double a 5th or the root. We should avoid doubling a 3rd because it is the most active tone in the triad. Finally, in connecting adjacent chords, we should strive to move via the shortest possible route and/or retain as many notes in common as possible.

When playing the outer-voice framework by itself, notice how effectively it expresses the underlying progression. In particular, the use of compound 3rds (or their inversions, compound 6ths) in the outer voices clarifies the harmonic meaning of the progression. This sound actually happens quite often and its influence on the progression is so powerful that other intervallic pairs get their harmonic definition from the relationship between the compound 3rds or 6ths. When examining the types of melodic motion between chords, notice that the outer-voice counterpoint primarily uses contrary and oblique motion. The use of contrary motion between outer voices is particularly important in progressions moving by step. The inner voices move mostly by step and employ common tones within the same voice.

In realizing progressions on the keyboard, develop a habit of starting with the outer-voice counterpoint and make sure that it features mostly contrary motion. Parallel motion between perfect intervals should be avoided, but similar motion between perfect intervals is acceptable. Strive for as many compound 3rds and 6ths as possible because these intervals clearly delineate the underlying harmony. In a triadic environment, the leading tone should be resolved up by a half step. Also, the treatment of a chordal 3rd should usually involve stepwise, upward resolution and common-tone retention, but rarely involves large leaps. Even though the progression from Figure 3.12 looks and sounds nothing like jazz, by practicing this and similar types of progression in the Workbook, the principles of voice leading are more readily internalized. This lays the foundation for more idiomatic jazz progressions in later chapters.

CHARACTERISTICS OF JAZZ HARMONY




* * *



Jazz harmonic syntax encompasses a plethora of different types of chord, from simple three-note triads to as many as eight-note structures. Within such a rich palette of possibilities, it is the four-part chord that constitutes the fundamental formation of jazz harmony. Just as triads were essential building blocks of common-practice music (ca. 1650–1900) so are four-part chords considered essential harmonies in jazz. Jazz harmonic syntax has evolved from common-practice music in the twentieth century in a similar manner that the latter had sprung from earlier modal theories of the 1600s and before. As such, jazz harmonic syntax is a part of a rich, constantly evolving musical language of tremendous variety. Even though we can pinpoint a lot of commonalities between jazz and common-practice music, syntactical differences between the two trump those similarities.

One essential difference between common-practice and jazz music relates to the status, role, and treatment of chordal dissonances. Unlike common-practice music, jazz allows chordal dissonances and therefore treats them in bold, new ways. The presence of four-part chords in jazz is as ubiquitous as that of triads in common-practice music. The chordal seventh or the sixth enhances the structure of chords, adds a kinetic force that energizes harmonic progressions, and permeates various levels of the musical structure. A four-part chord originates by adding one additional pitch to a triad. We refer to that note as an essential chord tone. To construct a four-part chord, add the following chord tones: a major 6th (6), a major 7th (Maj7), and a minor 7th (min7). Essential chord tones can be applied to major, minor, diminished, augmented, or suspended triads.

Figure 4.1 shows the addition of essential chord tones to the C major triad.





FIGURE 4.1 Addition of Essential Chord Tones


The addition of these three essential chord tones produces three different chords, each with a distinct intervallic structure, function, and sound. A sixth chord, C6, sounds very stable and is at rest. In labeling that chord, the “Maj” suffix in front of a “6” is omitted because C6 constitutes a commonly used label for the major triad with an added sixth. A major seventh chord, CMaj7, is a consonant entity with no particular voice-leading or resolution requirements.1 When C6 and CMaj7 are played in quick succession, we hear some common characteristics they share: both are major, use the same root, and are entirely diatonic (i.e. they only include notes from the C major scale).

Although a dominant seventh chord, C7, uses the same triadic foundation as C6 and CMaj7, it has a totally different harmonic function. The chord sounds as if it wants to move to a more stable sonority. The source of that inner tension and desire for harmonic resolution is the interval of a tritone between the major 3rd and the minor 7th of the dominant 7th chord.





CHORD CATEGORIES




* * *



To navigate through different chord types, the 14 four-part chords are divided into four functional categories. Even though these categories will suggest specific harmonic functions, we will discover that certain chords from different categories share the same harmonic function and that a single chord might have two different functional assignments. These functional overlaps that now might seem ambiguous will become clearer as we continue to advance in the study of jazz theory.





Major Category


Possible Harmonic Function—Tonic and Predominant

The major category includes the four chords shown in Figure 4.2.





FIGURE 4.2 Major Four-Part Chord


All the chords from Figure 4.2 have at least two common tones: the root and a major 3rd. With the exception of a sixth chord, C6, all the remaining chords also include a major 7th. The 5th is an expendable note that can be chromatically altered by either lower or upper half steps. In Figure 4.2, the 5th is replaced by the ♭5th in the major seventh flat five chord, CMaj7(♭5); and, the ♯5th in the major seventh sharp five chord, CMaj7(♯5).2 Both of these chords and their spellings preserve their tertian origins. A sixth chord and a major seventh chord are diatonic because they are derived from the pitches of the diatonic scale. The major seventh flat five and major seventh sharp five chords are chromatic because they contain pitch alterations that are not part of the diatonic scale. A generic Roman numeral for this category is Imaj7 (Xmaj7) or Imaj6 (Xmaj6).

These chords, which are arranged from more stable or diatonic to more unstable or chromatic, also share the same harmonic function and are tonally stable. Different as they may sound on the surface, these chords can be used interchangeably in the context of various harmonic progressions. Let us examine the pitch structure of these chords more closely.





Minor Category


Possible Harmonic Function—Tonic and Predominant

Figure 4.3 shows the pitch structure of three chords from the minor category.





FIGURE 4.3 Minor Four-Part Chords


The minor sixth chord, Cmin6, has a stable sound and represents a chord at rest. The minor major seventh chord, Cmin(♯7), is more unstable. Can you identify the pitch that is responsible for that characteristic sound? The minor seventh chord, Cmin7, is easily recognizable and one of the most commonly used chords in jazz. Its harmonic function is not, however, always apparent and largely depends on the context in which it occurs. For now, it suffices to say that in the context of ii7–V7–Imaj7 progression, a minor seventh chord built on will always function as the predominant. In other harmonic contexts, a minor seventh chord will most likely function as a tonic chord. A generic Roman numeral for this category is i7 or i6 (x7)/(x6).





Dominant 7th Category


Possible Harmonic Function—Dominant

The addition of a minor 7th to a major or suspended triad results in the formation of two distinct dominant 7th chords: regular with the major 3rd and suspended (sus) with the perfect 4th.3 Both chords are unstable and have a strong tendency to generate harmonic motion. The presence of a tritone between a major 3rd and a minor 7th of the dominant 7th chord is responsible for this harmonic and tonal instability. In the suspended dominant, a perfect 4th is the unsettling melodic agent that generates melodic motion and wants to resolve down to a major 3rd.4 Figure 4.4 shows four chords from the dominant 7th category.

The dominant seventh chord, C7, clearly projects the dominant function. The sus seventh chord, C7sus, is most easily identifiable with modal jazz.5 The dominant seventh flat five chord, C7(♭5) has a distinct intervallic structure featuring two interlocking tritones between the root and a ♭5th, and a major 3rd and a minor 7th: C4–G♭4 and E4–B♭4 in C7(♭5). The dominant seventh sharp five chord, C7(♯5), has an augmented triad at the bottom of its structure and projects a characteristic whole-tone sound. The dominant seventh flat five and the dominant seventh sharp five contain chromatic alterations of the diatonic 5th; this makes their structure even more unstable. A generic Roman numeral for this category is V7 (X7).





FIGURE 4.4 Dominant Four-Part Chords





Intermediary Category


Harmonic Function—Predominant, Dominant, Tonic

Figure 4.5 illustrates the intermediary category of four-part chords. The term “interme-diary” might seem odd; after all, this category features chords that could have easily been characterized as predominants (in the case of the min7(♭5) or half-diminished 7th) or dominants (in the case of the diminished 7th chord). The designation “intermediary” indicates that these chords have different roles in harmonic progressions.6





FIGURE 4.5 Intermediary Four-Part Chords


All of these chords have a diminished triad at the bottom of their structure. Chords from this category are associated with the predominant and dominant function. In more advanced harmonic situations, however, they may display different functions as well.

The minor seventh flat five chord, Cmin7(♭5), or the half-diminished seventh chord, Cø7, has a characteristic, unresolved sound. Two different labels can be used for a chord that sounds and looks the same. For now, the former functions as the predominant in the context of progression, and the latter participates in dominant-type situations.7 The diminished seventh chord, C°7, constitutes a perfectly symmetrical sonority with four minor 3rds dividing the octave into four equal parts. This important four-part formation originates from the addition of a diminished 7th to the diminished triad. This chord generally behaves as a dominant-functioning chord. The diminished major seventh, C°(♯7), acquires different harmonic functions (mostly dominant and tonic) and is probably the most dissonant formation from the collection of four-part chords.

Because of its important status, the minor 7(♭5) chord will be always notated as regardless of its position within the key. Its notational alias, the half-diminished 7th, is followed by an “ø” and will be labeled as “xø7,” regardless of its position within the key.

The 14 four-part chords compiled in Figure 4.6 have been shown in root position with the chordal root at the bottom of their pitch structure.





FIGURE 4.6 Fourteen Four-Part Chords





INVERSIONS OF FOUR-PART CHORDS




* * *



Broadly speaking, inversions illustrate different intervallic configurations of the same chord. Four-part chords can be shown in four positions: root position (the root in the lowest voice), 1st inversion (the 3rd in the lowest voice), 2nd inversion (the 5th in the lowest voice), and 3rd inversion (the essential chord tone in the lowest voice).

Figure 4.7 illustrates a root-position C6 chord with the three inversions.





FIGURE 4.7 Inversional Equivalence of C6 and Amin7


When examining each inversion, notice that the 3rd inversion of a C6 chord looks the same (i.e. is inversionally equivalent) as the root-position Amin7 chord. This observation is important because it allows us to use one chord in place of the other. But this mutual relationship also means that if a sixth chord in 3rd inversion is the same as a minor seventh chord in root position, then all inversions of the sixth chord can represent some form of the minor 7th chord. Figure 4.8 illustrates the 14 four-part chords in root position and three inversions.



FIGURE 4.8 Inversions of Four-Part Chords





FUNCTIONAL FAMILIES




* * *





Major Key


Figure 4.9 shows four-part chords built on each scale degree of C major. In addition to lead-sheet symbols and Roman numerals, each chord is identified with a function symbol that indicates its likely function in the harmonic progression.

The tonic on features two different chords: a 6th chord and a Maj7 chord. The supertonic () allows two minor chords: a min7 and a min6. The mediant () includes a min7 chord. The subdominant () allows two major chords: a 6th and a Maj7. The dominant on () features a dominant 7th. The submediant (), takes a min7. And the leading tone () features a half-diminished 7th chord. The chords built on , and share the tonic function, just as those built on , , and , , ; share predominant and the dominant functions respectively. Chords that share the same function will most likely share the same behavioral patterns in the context of harmonic progressions. In certain musical situations, therefore, chords of the same function can often be used interchangeably as substitutes of one another and, in more advanced situations, as chordal prolongations or expansions.





FIGURE 4.9 Four-Part Chords in Major Key


The situation gets a little more complex for chords on and . Chords built on these scale degrees have a dual harmonic function. Depending on harmonic context, chords on can either function as tonic or predominant. Furthermore, although chords built on and are major and chords on , and are minor, and share the same quality, they may nonetheless take a different harmonic function. What does this all mean? It means that the function of chords in jazz, as in classical music, is complex and is governed by strictly controlled laws, rules, procedures, and tonal conditions. These various principles influence voice-leading conventions, control the behavior of chords, and establish a unique musical grammar that is idiomatic for jazz. These rules also control the structure of musical compositions and allow us to make sense out of complicated harmonic progressions.

Figure 4.10 compiles three functionally related chords in major, each with the participating four-part chords.





FIGURE 4.10 Functional Families in Major Key





Minor Key


Figure 4.11 illustrates four-part chords built on each scale degree of A minor.

Once we start building chords on each scale degree of the harmonic minor as in Figure 4.12, or the melodic minor as in Figure 4.13, we are going to encounter even more chord types, intricate functional relationships, and some interesting discrepancies in labeling.

Before compiling three functional families of chords in minor, let us make some general observations about the structure and quality of individual chords occurring in minor keys. The tonic note () of the natural minor scale features a min7 chord and the tonic noteof harmonic minor takes a min(♯7) chord. Scale degree one () of the melodic minor scale uses both a min(♯7) and a min6 chord. The supertonic () of natural and harmonic minor uses a min7(♭5) chord, but in melodic minor it takes the form of a min7 chord. The mediant () highlights a Maj7 chord in natural minor, and a Maj7(♯5) in harmonic and melodic minor. The subdominant () features a min7 in natural and harmonic minor, and a dominant 7th in melodic minor labeled as IV7. The dominant note () uses a min7 in natural minor, and a dominant 7th in harmonic and melodic minor. The submediant on uses a major 6th and a Maj7 chord in natural and harmonic minor, but the raised submediant built on ♯, takes a min7(♭5) chord. The subtonic on of natural minor highlights a dominant 7th. The leading tone on ♯ of harmonic minor takes a diminished 7th chord (°7), and a half-diminished 7th chord (ø7), in melodic minor.





FIGURE 4.11 Four-Part Chords in Natural Minor





FIGURE 4.12 Four-Part Chords in Harmonic Minor





FIGURE 4.13 Four-Part Chords in Melodic Minor


Notice that two different labels are used for a chord that has the same pitch architecture and is made up of a diminished triad and an added minor 7th: the half-diminished 7th chord and the min7(♭5) chord. In jazz, these names are often used interchangeably. The half-diminished 7th chord occurs on the leading tone of the major key and the melodic minor, and, as such, functions as a dominant or a dominant substitute that is preceded by a predominant and followed by a tonic. The min7(♭5) chord occurs on the supertonic scale degree of natural and harmonic minor and the raised submediant of melodic minor. These chords always function as predominants and carry with them the expected voice-leading and harmonic behavior. In 99 percent of cases, the min7(♭5) chord remains in the context of progression.

Figure 4.14 compiles three functionally related chords in minor.

When examining the dominant-functioning chords in the natural minor, notice that the v7 chord has a minor quality typically associated with a tonic and predominant function. Its placement in this category, however, suggests that we may encounter this chord— mostly in modal tunes or minor blues tunes—functioning as a dominant.8





FIGURE 4.14 Functional Families in Minor Key





“DROP 2” VOICINGS




* * *



In jazz terminology, the term “voicing” refers to the arrangement of notes within a chord. That arrangement can be either close or open. In a close voicing the arrangement of notes is the most packed possible. In an open voicing, the arrangement of notes is intervallically more diverse. The most common method of generating an open voicing is to drop certain notes from a close-position chord down an octave. In a “drop 2” voicing, the second note, counting from the top note, is dropped down an octave. “Drop 2” refers to voicings above the bass in which the bass note is not counted as one of the voices being “dropped.” Each chord in Figure 4.15 includes three “drop 2” voicings because the three notes above the bass can be rotated three times.





FIGURE 4.15 “Drop 2” Four-Part Voicings


NOTES



* * *



1. In bold, I will provide complete names of chords, as jazz musicians are wont to call them. In naming chords, however, we will notice some inconsistencies and discover that certain chord symbols are spoken differently than the symbol suggests.

2. In a chord symbol, pitch alterations, and diatonic and chromatic extensions are written as superscripts and placed in parenthesis. Such a notation illustrates the pitch hierarchy occurring within the chord.

3. In Chapter 5, two separate categories for the dominant 7th chord will be established: the dominant 7th category and the suspended dominant category.

4. This type of melodic motion is knows as a 4–3 suspension. In common-practice music, this type of dissonance requires a special voice-leading treatment involving three steps: preparation, suspension, and resolution. Because these three steps are related to the underlying metric and rhythmic structure, the suspension is considered rhythmic rather than melodic dissonance. In jazz, the treatment of suspended sonorities is far more relaxed when you compare it to other types of music.

5. In spite of its dominant function, the sus chord can also function as tonic in modal compositions, such as Herbie Hancock's “Maiden Voyage,” Ralph Towner's “Icarus,” or McCoy Tyner's “Passion Dance.” The use of functional labels in the context of modal tunes, however, might be deceptive.

6. The term “predominant” would have been too restrictive and would not have shown the diverse functional status of intermediary chords. Besides, “predominant” is already being used for the specific harmonic function.

7. For more detailed explanation of the difference between the two, consult page 56.

CHORDAL EXTENSIONS




* * *



Chordal extensions consist of different forms of the ninth, the eleventh, and the thirteenth and can be divided into two broad categories: diatonic and chromatic. Diatonic extensions enhance the structure of chords, whereas chromatic extensions modify that structure in a considerable way. The ninth has three distinct forms: a diatonic major 9th, a chromatic ♭9th, and a chromatic ♯9th. The eleventh has two forms: a diatonic perfect 11th and a chromatic ♯11th. The thirteenth has two forms: a diatonic major 13th and a chromatic ♭13th.

In jazz terminology, we frequently encounter different labels for the same harmonic extensions. Sometimes these alternate labels are acceptable, other times they are not. For instance, we can find that the ♯11th is often referred to as the ♭5th or the ♯4th, whereas the ≤13th is called the ≥5th or the ♭6th. These are all acceptable enharmonic spellings and will occasionally be implemented throughout the book. However, if we want to be more rigorous in the labeling of extensions, we must determine how a particular note or a group of notes actually functions within a chord. In Chapter 4, certain chromatic notes—the ♭5th and ≥5th in particular—were referred to as alterations of diatonic pitches. For instance, a ♭5th in the Maj7(♭5) chord and a ♯5th in the dom7(♯5) chord were called chromatic alterations and not chromatic extensions. The addition of a 9th to these four-part chords does not affect the status of these alterations. However, one would probably use the ♯11th label for an extended tertian structure with the diatonic fifth present. On the contrary, the use of the ♯11th label in the suspended dominant 7th chord is functionally and sonically incorrect because a ♯11th and a perfect 4th do not work well together. A 13th is the extension that is frequently labeled as a major or minor 6th. The note is referred to as a 13th if the 7th is present; the 6th if not. You may also wonder why there is no reference to the 9th as a 2nd. The basic reason has to do with the presence of the essential chord tone within a harmony. If a chord contains an essential chord tone, then any note added to its structure functions as an extension. The Maj7 chord does not include a major 2nd, but a major 9th. The dominant 7th chord does not include a ♭2nd, but a ♭9th. Therefore, chord labels, such as C7(♭2) or CMaj7 should be avoided.





ADDITION OF EXTENSIONS




* * *



Not only do we have to know how to correctly label chordal extensions, but we also have to know which extensions can be added to four-part chords and how those extensions can be used. Here are some broad generalizations.

The major chord contains two essential chord tones—a major 7th and a major 6th; two diatonic extensions—a major 9th and a major 13th; one chromatic extension—a ♯11th; and two pitch alterations—a ♭5th and a ♯5th. The minor chord admits four essential chord tones—a minor 7th, a major 6th, a major 7th, and a minor 6th; three diatonic extensions— a major 9th, a perfect 11th, and a major 13th; and two chromatic extensions—a ♭13th and a ♯11th. The minor 7(♭5) chord (also known as the half-diminished 7th) allows one essential chord tone—a minor 7th; two diatonic extensions—a major 9th and a perfect 11th; and one chromatic extension—a ♭13th. The diminished 7th chord uses two essential chord tones—a diminished 7th and a major 7th; and three extensions—a major 9th, a perfect 11th, and a ♭13th. The dominant 7th chord contains one essential chord tone —a minor 7th; two diatonic extensions—a major 9th and a major 13th; four chromatic extensions—a ♭9th, a ♯9th, a ♯11th, and a ♭13th; and two pitch alterations—a ♭5th and a ♯5th. The suspended dominant chord includes one essential chord tone—a minor 7th; two diatonic extensions—a major 9th and a major 13th; three chromatic extensions—a ♭9th, a ♯9th, and a ♭13th; and two pitch alterations—a ♭5th and a ♯5th. Figure 5.1 summarizes the distribution of essential chord tones, pitch alterations, and extensions in Maj7, min7, dom7, suspended dominant, min7(♭5), and diminished 7th chords.





FIGURE 5.1 Essential Chord Tones—Pitch Alterations—Extensions





CHORD CATEGORIES




* * *



The categories for five-part chords suggest the possible harmonic function of chords. They are analogous to the similar categories established for four-part formations. Unlike in Chapter 4, where 14 four-part chords were built on the same starting pitch, the five-part chords are built on the specific scale degrees that suggest their likely occurrence in harmonic progressions: major chords on , minor chords on , dominant chords on , and intermediary chords on . By placing them in these locations, we can notice how their scale-degree position affects their pitch content. As far as the use of Roman numerals for five-part chords is concerned, we will only indicate their basic four-part structure, notating neither extensions nor alterations, just as we did with the generic Roman numerals for four-part chords. The functional behavior of five-part chords depends on the specific context in which they are encountered. For instance, even though minor chords appear on , which implies the predominant function, on a different scale degree they can also function as tonics. A chord from the major category might function as a tonic or a predominant depending on its role and position in the chord progression, etc. The five-part chord includes a four-part base structure and some type of a 9th. In order to keep its extension status, the 9th must be located a ninth above the root of the chord.





Major Category


Harmonic Function: Tonic and Predominant

Figure 5.2 shows four major five-part chords in close position.

A sixth nine chord, C6/9, represents the harmonic style of earlier jazz, particularly that from the Swing Era. A major ninth chord, CMaj9, is probably the most commonly utilized chord in jazz. A major ninth flat five, CMaj9(♭5), and a major ninth sharp five, CMaj9(♯5), represent more of the contemporary jazz styles.





FIGURE 5.2 Major Five-Part Chords





Minor Category


Harmonic Function: Tonic and Predominant

Figure 5.3 shows four minor five-part chords in close position. Note that they are built on of C major.



FIGURE 5.3 Minor Five-Part Chords


In the previous chapter, the minor category of four-part chords consisted of three formations: min6, min7, and min(♯7). In this category we meet a new member: the minor ninth flat sixth chord. The inclusion of this formation fits the present context better because of the status of ♭6th, which we have yet to discuss. The flat sixth added to a minor triad makes the four-part chord look exactly like a major 7th chord in third inversion. In the context of five-part chords, however, the use of a ♭6th is justifiable because its addition creates an autonomous root-position five-part formation that is relatively common in contemporary jazz styles. A minor sixth nine chord, Dmin6/9, embodies the tonic function. A minor ninth chord, Dmin9, is probably the most versatile chord type since it can function as a tonic or a predominant. A minor ninth flat sixth chord, Dmin9(♭6), has a darker sound to it and is largely associated with the tonic function. Depending on its role within harmonic progressions, a minor ninth major seventh chord, Dmin9(♯7), can function as a tonic or a predominant.





Dominant and Suspended Chords


Five-part dominant 7th chords feature an impressive variety of harmonic formations. Their diversity comes from the largest number of available extensions that can be added to their pitch structure. Given that diatonic and chromatic extensions can be combined with one another in a number of creative ways and that there are only two fundamental dominant 7th chords, the family of dominant chords can seem overwhelming. Therefore, in the investigation of five-part dominant 7ths, two distinct categories—the dominant 7th category and the suspended dominant category—are established.





Dominant 7th Category


Possible Harmonic Function—Dominant

Figure 5.4 shows 12 close-position five-part chords from the dominant 7th category built on of C major.

Each line features a different type of the ninth added to the four-part chord. The first line contains a major 9th; the second, a ♭9th; and the third, a ♯9th. Each line features four five-part chords; they originate by replacing the 5th with a lower chromatic neighbor— ♭5th; an upper chromatic neighbor—♯5th; and an upper diatonic neighbor—major 13th.

A dominant ninth chord, G9, is a diatonic formation and is derived from the notes of F major.1 A dominant ninth flat five, G9(♭5), has a sound that is frequently heard on recordings from the Bebop Era. A dominant ninth sharp five, G9(♯5), includes an augmented triad at the bottom of its structure. A dominant thirteenth chord, G13, is entirely diatonic and features the characteristic minor 2nd between a major 13th and a minor 7th.2

A dominant seventh flat ninth chord, G7(♭9), contains a diminished 7th chord built on the major 3rd. A dominant seventh flat ninth flat five chord, G7, is highly chromatic and highlights a major triad built on the ♭5th. A dominant seventh flat ninth sharp five chord, G7, is commonly used as a dominant 7th in minor keys. A dominant thirteenth flat ninth chord, G13(♭9), includes an enharmonically spelled major triad built on the 13th.





FIGURE 5.4 Dominant Five-Part Chords


A dominant seventh sharp ninth chord, G7(♯9), has a dissonant sound that is frequently used in Jazz Rock. A dominant seventh sharp ninth flat five, G7, contains an enharmonically equivalent minor triad built on the ♯9th. A dominant seventh sharp ninth sharp five, G7, is a quintessential altered chord that is frequently labeled as G7alt. A dominant thirteenth sharp ninth, G13(♯9), has a characteristic minor 2nd clash between a major 13th and a minor 7th that, together with the ♯9th, creates a very dissonant sonority.





Suspended Dominant Category


Possible Harmonic Function—Dominant, Predominant, Tonic

Figure 5.5 shows 12 close-position five-part chords from the suspended dominant category built on of C major.

The chords from Figure 5.5 can function as dominants, predominants, or even as “tonics” in certain modal tunes. The predominant status stems from the fact that they often precede a regular dominant 7th chord. That is because the suspended dominant 7th chord includes a perfect 4th which, on the one hand, initiates melodic motion that requires resolution, and on the other can be reinterpreted as the minor 7th of a local ii7.

A sus ninth chord, G9sus, is a basic suspended formation.3 A sus ninth flat five chord, G9(♭5)sus, features an augmented triad built on the ♭5th. A sus ninth flat thirteenth chord, G9(♭13)sus, has a characteristic blues flavor to it on account of an enharmonically spelled dominant 7th chord built on the 7th. A sus thirteenth chord, G13sus, contains a minor triad build on the 9th of the chord.





FIGURE 5.5 Suspended Dominant Five-Part Chords


A sus seven flat ninth chord, G7(♭9)sus, has strong voice-leading propensities that compel the 4th and the ♭9th to resolve downward by a half step. A sus seven flat ninth flat five chord, G7sus, features a Maj7 chord built on the ♭5th. A sus seven flat ninth sharp five chord, G7sus, contains an enharmonically respelled min7 chord built on the 7th of the chord. A sus thirteenth flat ninth chord, G13(♭9)sus, has a min(♯7) chord built on the 7th.

A sus seven sharp ninth chord, G7(♯9)sus, sounds like an extended minor chord and demonstrates the ambiguous nature of suspended formations. This ambiguity is something that we can capitalize on in harmonic progressions. A sus seven sharp ninth flat five chord, G7sus, shows strong predominant characteristics. A sus seven sharp ninth sharp five chord, G7sus, sounds tonally ambiguous (like all other suspended chords) and can only be tonally and functionally defined in the context of specific chord progressions. A sus thirteenth sharp ninth chord, G13(♯9)sus, illustrates yet another tonally and functionally ambiguous suspended formation.





Intermediary Category


Possible Harmonic Function—Predominant, Dominant, Tonic

Figure 5.6 shows three intermediary chords built on of C major.





FIGURE 5.6 Intermediary Five-Part Chords


A minor ninth flat five chord, Dmin9(♭5), or a half-diminished ninth chord, Dø9, has a unique characteristic sound on account of a min(♯7) chord built on the 3rd of the chord. Notice that two different labels are used for the same chord. The “min9(♭5)” suffix implies a predominant function, and the “ø9” suffix suggests a dominant function. The former occurs in the context of the progression; the latter is much rarer but can occur in the progression viiø7–I or, rarer still, in the progression ♯viiø7–i. A diminished ninth chord, Do9, has strong melodic and voice-leading tendencies. A diminished major ninth major seventh chord, Do9(♯7), has a pliable structure with interesting functional associations. Both of these chords can also function as upper structures of altered dominant 7ths.





POSITIONS OF CHORDS




* * *



In the discussion of “inverted” five-part chords, the term “positions” is used instead of inversions. Unlike four-part formations in which notes are contained within an octave, five-part chords overshoot the octave by a 2nd; this renders the use of inversions awkward and impractical. Thus, in generating positions, we will first drop the 9th down an octave and subsequently invert the chord. Figure 5.7 illustrates positions of five-part chords. The CMaj9 chord in Figure 5.7, and all the remaining chords, exhibit different pitch architectures: the first one uses an extended tertian structure and the second has a diatonic cluster at the bottom of the chord. In the first position of the C6/9, a 9th is in the lowest voice; second position has a 3rd; third position has a 5th; and fourth position has a 7th in the lowest voice.

The chords in Figure 5.7 represent various close voicings, but there are many, many more ways to orchestrate a chord, such as those in Figure 5.8.





“DROP 2” VOICINGS




* * *



Figure 5.8 illustrates “drop 2” voicings for the root-position five-part chords. Each chord in Figure 5.8 includes four “drop 2” voicings because the four notes above the bass can be rotated four times.





FIGURE 5.7 Positions of Five-Part Chords





FIGURE 5.8 “Drop 2” Five-Part Voicings


NOTES



* * *



1. The presence of a minor 7th is implied with the term “dominant ninth.”

2. In the term “dominant thirteenth,” the 13th implies a 7th, but does not require a 9th.

3. In labeling suspended chords, we do not include the 11th in the symbol. A “sus” takes care of that.

A BRIEF HISTORY




* * *



Nowhere are the principles of jazz harmonic syntax more evident and its grammatical rules more explicit than in the structure and behavior of the II–V–I progression. The evolution of the progression offers a fascinating journey through jazz history. The origins of the II–V–I can be traced back to fundamental V–I motion, which is the most important chord succession in common-practice music and the marker of tonality. When we compare jazz performances from different historical periods, we notice that the structure of the II–V–I progression has been in a state of constant flux. In Early Jazz, for instance, the ii7–V7–Imaj7 was not always present; the more idiomatic V7–I motion often implied the structural notes of the progression. Figure 6.1 illustrates mm. 1–4 of “Maple Leaf Rag” by Scott Joplin.

Even though in the bass does not support a ii7 chord, the design of the bass voice seems to imply a ii7–V7–Imaj7 progression. A similar treatment of the dominant 7th, yet with an idiomatic use of chordal inversions, occurred in the Swing Era with one notable exception. The structure of V7–I was infused with various kinds of diminished 7th chord, as demonstrated in Figure 6.2.1

Harmonic expansions such as this one ultimately led to the explosion of chromaticism during the Bebop Era. By the 1940s, the ii7–V7–Imaj7 progression was fully formed and commonly implemented. In addition, intricate chromatic variants began to infiltrate the structure of harmonic progressions, making improvisation more challenging. What is remarkable about Charlie Parker, Thelonious Monk, Dizzy Gillespie, and other artists from that period is that they showed endless creativity in negotiating and utilizing the major and minor versions of the II–V–I progression.2 As the Post-Bop Era rolled in, artists such as Miles Davis, Horace Silver, Lennie Tristano, and many others found new and ingenious ways to implement the progression in their music.3 One of the most radical transformations of the progression, however, occurred in the late 1950s in the creative mind of John Coltrane.4 His experiments with symmetrical intervallic cycles led to the development of so-called “Coltrane” substitutions.5



FIGURE 6.1 “Maple Leaf Rag” by Scott Joplin, mm. 1–4



FIGURE 6.2 Diminished 7ths in V7–I

Constantly searching for a new means of personal expression while being respectful and mindful of the rich genre’s traditions, jazz musicians did not advance their harmonic experiments in a creative vacuum. It seems that, in fulfilling their own artistic destiny, each generation of jazz musicians benefited from the achievements of the previous generation. This is true even today, as the merger of tonality and modality in the 1960s still resonates well with many contemporary jazz artists further transforming or disguising the structure of the II–V–I progression. The II–V–I progression, with its two tonal variants ii7–V7–Imaj7 and , is the fundamental harmonic block of tonal jazz and its ubiquity in standard tunes confirms its structural importance. Yet, the sheer number of harmonic transformations that jazz musicians have been able to implement is truly remarkable and proves the progression’s flexibility in adjusting to various jazz styles. This makes our study of the II–V–I progression all the more relevant.





THE ii7–V7–Imaj7 PROGRESSION




* * *



The ii7–V7–Imaj7 progression, shown in Figure 6.3, combines three harmonic functions: the predominant, the dominant, and the tonic.



Each chord of the progression is reduced to its essential members with the 3rd and 7th being known as the guide tones. The guide tones have two basic roles: (1) to determine the quality and functionality of chords, and (2) to dictate the voice leading and proper unfolding of chords within harmonic progressions. In this way, guide tones “guide” the improvisation and, through their careful distribution within a phrase, assure melodic continuity and harmonic clarity. Figure 6.3 includes two versions of the ii7–V7–Imaj7 progression where the second version inverts the position of the guide tones of the first. The inverted version of the progression sounds a little different from the original. By exploring the potential of invertible counterpoint (which is inherent to two-voice and larger harmonic textures), we fundamentally redefine the way of thinking about harmony. Chords can be considered not only as vertical formations, but also as byproducts of individual lines. In a sense, we are still thinking about chords and harmonic progressions, but we are doing so from a linear rather than vertical perspective.





FIGURE 6.3 The ii7–V7–Imaj7 Progression

The guide tones in Figure 6.3 form two independently moving lines that start on the 7th and the 3rd of a predominant harmony. The voice leading of the progression depends on the kinetic force of the guide tones: the 7th of ii7 or V7 descends down to the 3rd; and the 3rd of ii7 or V7 becomes the 7th. To finish its trajectory, the major 7th of the tonic chord moves down to a more stable major 6th at the end of the progression. Besides determining the quality and function of chords, the individual tones of the guide-tone line have the potential of being reinterpreted as chord tones or as extensions of other harmonic formations.





THE PROGRESSION




* * *





The progression, shown in Figure 6.4, behaves in much the same ways as its major counterpart.6 The presence of the min7(♭5), as a predominant, implies the choice of specific extensions in the forthcoming dominant 7th chord. In particular, the use of the ♭9th in V7 illustrates an ideal voice-leading scenario in which the ♭5th of is retained as a common tone and becomes the ♭9th of V7.





FIGURE 6.4 Progression





SECONDARY DOMINANT 7TH




* * *



One of the most common transformations of the ii7–V7–Imaj7 progression involves the use of secondary or applied dominant 7th chords (notated as V7/V or X7). Secondary or applied dominant 7ths built on the supertonic scale degree require a secondary leading tone on ♯. With that addition, the secondary dominant temporarily tonicizes the upcoming dominant 7th on . Figure 6.5 illustrates the use of a secondary dominant within a ii7–V7–Imaj7 progression.



FIGURE 6.5 Secondary Dominant 7th



The guide-tone line features a chromatically altered note, F♯4. The voice-leading tendency of the F♯4 up to G (leading tone motion in G) and the passing tone motion of G5 moving through F4 down to E4 are subsumed into a single descending gesture known as a melodic elision. The behavior of the secondary leading tone, F♯4, causes harmonic motion where no motion was before. The F♯4 replaces F4, which would have been a common tone between Dmin7 and G7.





THE DIMINISHED 7TH CHORD




* * *



Although the diminished 7th chord and its chromatic variant, the diminished major 7th chord, belong to the intermediary family of chords, its role in harmonic progressions is quite unlike that of any other chord. There are three basic types of the diminished 7th chord: passing, neighbor, and common tone. The passing diminished 7th chord fills the space between two diatonic chords. The lower or upper chromatic neighbor diminished 7th chord embellishes chord tones of a structural chord from below or above by a half step. These chordal embellishments typically occur on weak metric positions. The unaccented common-tone diminished 7th chord retains the two outer notes of another chord and moves the inner two down a minor 2nd before returning to the original chord. This type of harmonic embellishment is highly idiomatic, especially in the blues, where the active notes or blue notes (the ♭3 and the ♭5) move to a major 3rd and a perfect 5th of major or dominant 7th chords. The common-tone diminished 7th chord can also occur in minor chords where the ♭5th moves up to a perfect 5th, while a minor 3rd stays as the common tone. The accented common-tone diminished 7th chord shares the root with the structural chord and, typically, foreshadows its arrival on a strong metric position. The most common harmonic function of the diminished 7th chord—one that will be emphasized in the discussion of Bebop in Chapter 15—is the dominant-functioning viio7 or an incomplete dom7(♭9) chord.

As an important jazz harmonic structure, the diminished 7th chord can effectively participate in the elaboration of ii7–V7–Imaj7 or progressions. In order to explore the full potential of the diminished 7th chord, these progressions will be first deconstructed to their individual members. Then, specific types of the diminished 7th chord that can embellish these chords will be examined. Finally, the progressions will be assembled to their original form and embellished with different types of the diminished 7th chord. Figure 6.6 illustrates this process. Because the full names for specific diminished 7th chords are quite long, the following abbreviations will be implemented:

1. the diatonic passing diminished 7th—DP

2. the chromatic passing diminished 7th—CP

3. the diatonic neighbor diminished 7th—DN

4. the chromatic neighbor diminished 7th—CN

5. the common-tone diminished 7th—CT.

Figure 6.7 demonstrates some of the most interesting interpolations of different types of the diminished 7th chord within the II–V–I progression realized with “drop 2” four-part voicings. Although there are far fewer choices for the use of the diminished 7th in the progression, Figure 6.7f illustrates an example that includes multiple passing diminished 7th chords. The reason that only a limited number of diminished 7th chords can participate in the progression stems from the quality and functionality of the : unlike its major counterpart, the min7(♭5) cannot be tonicized as a separate key area and, therefore, the diminished 7th chord cannot be used as a tonicizing formation.





TRANSFORMATION OF THE DIMINISHED 7TH CHORD




* * *



Figure 6.8 illustrates a voice-leading transformation of the diminished 7th chord into a chromatic ii7–V7 using “drop 2” voicings.

A subtle contrapuntal motion from a ♭5th and a ♭♭7th of the diminished 7th chord to a perfect 5th and a minor 7th of the minor 7th chord generates this voice-leading transformation. A minor 7th chord, then, pairs up with its local dominant 7th to create a chromatic ii7–V7 interpolation. With the voice-leading transformation from Figure 6.8, we can further modify the structure of the diatonic ii7–V7–Imaj7 from a common Swing Era progression to an idiomatic Bebop progression. The chromatic ii7–V7s are notated in square brackets followed by a diagonal line and a Roman numeral that indicates the subsumed resolution of the chromatic ii7–V7. This particular use of ii7–V7s is known as a harmonic elision.

The progressions in Figure 6.9 are realized with “drop 2” five-part voicings. Notice that the voice leading between chords is entirely dependent on the behavior of the guide tones. With the exception of the bass voice (which is unaffected by “drop 2”), all other voices move mostly by step.

PARENT-SCALE DERIVATION OF DIATONIC MODES




* * *



In modal jazz theory, diatonic modes are traditionally introduced as derivatives of the parent major scale. What might be a bit confusing in this method is that the parent scale is also a mode, named Ionian. The parent-scale method is based on constructing modes on the consecutive pitches of the major scale. In Figure 7.1, Dorian begins on of the C major scale and represents an ordered diatonic collection stretching from D4 to D5 (or any other octave); Phrygian starts on and covers an octave from E4 to E5; Lydian begins on and spans an octave from F4 to F5; Mixolydian starts on and extends from G4 to G5; Aeolian begins on and covers the distance from A4 to A5; and Locrian starts on and includes pitches between B4 and B5. Figure 7.1 shows the derivation of modes using the parent-scale methodology.

While parent-scale derivation is an important theoretical construct, it strips individual modes of their salient characteristics and is cumbersome in actual musical practice. Imagine, for instance, trying to quickly figure out the Phrygian mode on F♯. Using this methodology, we have to first determine which major scale contains F♯ as a major 3rd. Then, based on the fact that the D major scale indeed contains the pitch F♯ as the major 3rd, we can build the Phrygian mode using the notes from the D major scale. Cumbersome? Yes. Even more troublesome than the mode derivation itself, however, is the fact that this method seems to focus on the parent scale rather than on the pitch structure of specific modes. Our methodology eliminates such two-step modal conversion and focuses on modes as individual pitch collections with their own melodic, harmonic, and structural properties. By building modes starting on the same pitch and concentrating on their sound, essential tones, and pitch hierarchy, we can understand their pitch structure more quickly.



FIFURE 7.1 Parent-Scale Derivation of Diatonic Modes





THE MODES’ CHARACTERISTICS




* * *



Broadly speaking, there are two types of modes: major and minor. Major modes have a major 3rd and minor modes contain a minor 3rd. These notes are called modal qualifiers. This rough classification is by no means complete but should help to unravel the principles of modal theory. The distinction between major and minor modes enables easier aural identification. Within seven diatonic modes, three are major and four are minor. The beauty mark is a term that indicates the essential tone or tones indicative of the mode. The beauty mark, then, is an absolutely crucial tone to convey the sound and distinguish between different modes. Avoid notes are pitches within the mode that do not quite fit the structure of certain chords or melodic lines. For instance, the perfect fourth of the Ionian mode might be problematic if we try to use it over CMaj7 or CMaj9. Also, the major 3rd of the Mixolydian mode might sound dissonant if we try to use it over C7sus of C7(♭9)sus without proper preparation. Thus, the term “avoid” should alert us about potential problems that might arise while trying to use these notes in harmonic or melodic contexts. In the case of extended six- or seven-part chords (especially those that feature chromatic extensions), however, the avoid note can sometimes be admitted as one of the chord tones or unusual extensions. For instance, the fully extended tertian formation CMaj(13♭11) includes the perfect fifth in its structure, which in the context of CMaj7(♭5) and CMaj9(♭5) would have created a harsh dissonance against the ♭5th.





DIATONIC MODES




* * *



As mentioned in Chapter 1, the specific pattern of whole steps and half steps occurring in the major scale forms a type of diatonic collection. Other diatonic scales are formed by preserving the same number of whole and half steps yet distributing them at different locations within the scale. These types of scale are referred to as diatonic modes.





Major Modes—Ionian


Figure 7.2a provides the pitch content of the Ionian mode with each note examined according to its function within the collection. Figure 7.2b illustrates a four-bar modal phrase that projects the Ionian sound using a CMaj7 harmony.



FIGURE 7.2A Ionian Mode



FIGURE 7.2B Ionian Phrase

In order to convey the sound of the Ionian mode, only two pitches are needed: a major 3rd as the modal qualifier and a major 7th as the beauty mark. The 3rd and the 7th of the mode also function as the guide tones. Scale degree four () of the mode is a note that should be treated with caution.1 In Figure 7.2b, it is used as a diatonic passing note (PN) and is located at the “and” of beat 2 or the upbeat (offbeat) in m. 2. The metric distribution of pitches within a phrase is an important factor in enabling the clear projection of a mode. In Figure 7.2b, the chord tones of CMaj7 are mostly located on the downbeats unless they form arpeggiation patterns, which might affect their distribution.





Major Modes—Lydian


The Lydian mode is a diatonic mode with a more contemporary sound. Figure 7.3a illustrates the pitch structure of Lydian and Figure 7.3b demonstrates a four-bar modal phrase with Lydian characteristics over a CMaj7(♭5) harmony. Henceforth, Arabic numbers are used (with appropriate accidentals) to indicate the pitch structure of modes and—in the forthcoming chapters—bebop scales, octatonics, pentatonics, hexatonics, and melodic patterns. Scale-degree labels (, , , etc.) are reserved for pitches occurring within the context of the underlying key.

When comparing the structure of Lydian with Ionian, the presence of ♯11 (♯4) as the beauty mark gives the Lydian collection its unique characteristics. Depending on its position within the chord, the beauty mark can be spelled either as a ♭5th (in chords without the perfect 5th, such as CMaj7(♭5)) or as a ♯11th (in chords with the perfect 5th, such as CMaj13(♯11)). The distribution of chord tones on metrically strong positions within a measure contributes to a clear projection of Lydian characteristics. Note that the avoid note, 5, is excluded from the context of the phrase. The intervallic structure of the phrase prioritizes the use of fourths, one of the main building blocks in modal improvisation.



FIGURE 7.3A Lydian Mode



FIGURE 7.3B Lydian Phrase





Major Modes—Mixolydian


Even though the Mixolydian mode belongs to the major family of modes, it has a distinct functional status and behavior that is entirely different from Ionian and Lydian modes. Figure 7.4a demonstrates the pitch structure of Mixolydian and Figure 7.4b provides a four-bar modal phrase with Mixolydian characteristics over a C7 harmony.

The presence of ♭7 as the beauty mark makes the phrase tonally unstable with a strong tendency to resolve on to a more stable chord. The status of 4 as a diatonic passing note in m. 4 deserves our attention. Since the 4th can also participate in the context of the suspended dominant and, as such, it replaces the major 3rd of the dominant 7th chord, the metric placement of that pitch within the phrase might change the overall chord-scale relationship from C7 to C7sus. In Figure 7.4b, the mode clearly projects the sound of the underlying C7 harmony.



FIGURE 7.4A Mixolydian Mode



FIGURE 7.4B Mixolydian Phrase





Minor Modes—Aeolian


The pitch structure of the four minor modes contains ♭3, ♭6 (♮6), and ♭7 as modal qualifiers. These tones are members of the natural minor scale from which other minor modes are derived. In certain modes, however, the minor or major 6th will additionally function as the beauty mark. The natural minor scale in modal environment is known as the Aeolian mode. Figure 7.5a examines the pitch structure of Aeolian. Figure 7.5b illustrates a four-bar modal phrase with a characteristic Aeolian flavor over a Cmin9(♭13) harmony.

The beauty mark, minor 6, injects a darker sound to the mode that stands in stark contrast to the sound of other minor modes. The phrase in Figure 7.5b uses the Cmin(9♭13) chord, which indicates an extended tertian structure. The metric distribution of chord tones and extensions shows equal metric treatment of the diatonic extensions, 9th and 11th, and the chromatic extension, ♭13th.



FIGURE 7.5A Aeolian Mode



FIGURE 7.5B Aeolian Phrase





Minor Modes—Dorian


Figure 7.6a illustrates the pitch structure of Dorian mode and Figure 7.6b demonstrates a four-bar modal phrase with Dorian characteristics over a Cmin13 harmony.

Even though Dorian is a minor mode, its beauty mark, major 6, gives the collection a characteristic “major” sound. The phrase in Figure 7.6b projects the tertian nature of the Cmin13 harmony by clearly arpeggiating triads (B♭ and E♭ in mm. 1–2), four-part chords (Amin7(♭5) in mm. 3 and 4, and Gmin7 in m. 3), and a five-part chord (Gmin9 in mm. 2–3).



FIGURE 7.6A Dorian Mode



FIGURE 7.6B Dorian Phrase





Minor Modes—Phrygian


The Phrygian mode has a distinctive sound because of its unusual beauty mark, ♭2. The pitch structure of the Phrygian collection is given in Figure 7.7a. Figure 7.7b demonstrates a five-bar modal phrase with Phrygian characteristics.

Even though the phrase does not have a corresponding chord and, as such, can be performed over a C pedal point, it nonetheless demonstrates strong minor qualities. A pedal point features a single note in the bass that controls larger sections of music. Note that the modal qualifiers and the beauty mark are featured prominently throughout the phrase.



FIGURE 7.7A Phrygian Mode



FIGURE 7.7B Phrygian Phrase





Minor Modes—Locrian


The last diatonic minor mode deserves a special place in our discussion because of its flat-out rejection from the modal family for centuries.2 The Locrian mode has two beauty marks: ♭2 and ♭5. Because of its unusual pitch structure, which prevents the occurrence of minor triad on 1, Locrian is characterized by a highly unstable sound. It still belongs to the minor family of modes because it contains a minor 3rd. Figure 7.8a examines the pitch structure of the mode. Figure 7.8b demonstrates a four-bar modal phrase over a C pedal.

The melodic phrase has an unsettling quality that is constantly reinforced by the tritone between 1 and ♭5 (mm. 1, 3, and 4). The phrase in Figure 7.8b also horizontalizes four-and five-part structures. For instance, a downward arpeggiation of E♭nin7 in mm. 1–2 and an upward arpeggiation of E♭min9 in mm. 3–4 create harmonic and melodic tensions with the underlying C pedal.



FIGURE 7.8A Locrian Mode



FIGURE 7.8B Locrian Phrase





PARENT-SCALE DERIVATION OF CHROMATIC MODES




* * *



The so-called modes of melodic minor, also known as the chromatic modes, are traditionally derived using the parent-scale principle. Using this method, the melodic minor collection functions as the parent scale. The pitch structure of chromatic modes is much more diverse than it is in the diatonic modes. In Figure 7.9, Dorian ♭2 begins on of C melodic minor and extends from D4 to D5; Lydian Augmented starts on and spans an octave from E♭4 to E♭5; Mixolydian ♯11 begins on and covers the distance between F4 and F5; Mixolydian ♭13 starts on and spans an octave from G4 to G5; Locrian ♯2 begins on ♯ (major 6th) and extends from A4 to A5; and Altered begins on ♯ (major 7th) and spans from B4 to B5 of C melodic minor. Figure 7.9 illustrates the derivation of chromatic modes using the C melodic minor as a parent scale.



FIGURE 7.9 Parent-Scale Derivation of Chromatic Modes





CHROMATIC MODES




* * *



The family of chromatic modes includes three minor and four major collections—each with its unique pitch architecture, beauty marks, functional roles, and sound. Each mode will be additionally analyzed in terms of two four-note pitch segments called tetrachords. In this context, the lower tetrachord refers to the four notes derived from the scale (–); the upper tetrachord combines the remaining four (–()). We will encounter different combinations of the following tetrachords: major (2–2–1), minor (2–1–2), whole tone (2–2–2), Phrygian (1–2–2), chromatic (1–2–1) and harmonic (1–3–1). Arabic numbers refer to the number of semitones between adjacent pitches.





Minor Modes—Melodic Minor


Figure 7.10a examines the pitch structure of the Melodic Minor mode.3 Figure 7.10b illustrates a four-bar modal phrase over a Cmin9(♯7) that captures the sound of the mode. The structure of the mode highlights two tetrachords: lower minor and upper major that contains two beauty marks: major 6 and major 7. In Figure 7.10b, the minor quality of the mode is clearly established by the presence of the minor 3rd. The mode’s dissonant character is emphasized with two beauty marks located at metrically strong positions within the phrase. For instance, B5 constitutes the highest pitch within the phrase and initiates a downward arpeggiation of B+.



FIGURE 7.10A Melodic Minor Mode



FIGURE 7.10B Melodic Minor Phrase





Minor Modes—Dorian ♭2


The Dorian ♭2 mode also contains two beauty marks: major 6 and ♭2. Figure 7.11a examines the pitch structure of Dorian ♭2. Figure 7.11b demonstrates a four-bar modal phrase with Dorian ♭2 characteristics composed over a C13(♭9)sus harmony.



FIGURE 7.11A Dorian ♭2 Mode



FIGURE 7.11B Dorian ♭2 Phrase

The pitch structure of the mode includes two tetrachords: the lower Phrygian and the upper minor. The modal phrase in Figure 7.11b capitalizes on the two salient features of Dorian ♭2: (1) the sound of an augmented triad on ♭2 (mm. 2 and 3), and (2) the whole-tone segment stretching from ♭2 to 6 (mm. 3–4).





Minor Modes—Locrian ♮2


The Locrian ♮2 mode contains two beauty marks: ♭5 and ♮2.4 Figure 7.12a analyzes the pitch content of the mode and Figure 7.12b illustrates a four-bar modal phrase that utilizes salient characteristics of the mode over a Cmin7(♭5) harmony.

Locrian ♭2 contains two tetrachords: lower minor and upper whole tone. The melodic line in Figure 7.12b conveys the dissonant character of the mode by highlighting the beauty marks—♭5, in particular. The arpeggiation of the underlying harmony in m. 1 prioritizes chord tones (root, 3rd, ♭5th, ♭7th) and the diatonic extension (9th), which is metrically stressed on beat 3. In comparison to the phrase in Figure 7.8b, where the ♭9th occurring in the context of Locrian was metrically de-emphasized, the phrase in Figure 7.12b amplifies the status of the 9th as an extension that better fits the content of the Cmin(♭5) harmony.



FIGURE 7.12A Locrian ♮2 Mode



FIGURE 7.12B Locrian ♮2 Phrase





Major Modes—Lydian Augmented


In addition to the three minor modes, the melodic minor scale gives rise to the four major chromatic modes, each with its own pitch structure, beauty marks, functional role, and characteristic sound. Figure 7.13a illustrates the structure of the Lydian Augmented mode along with an analysis of its pitch content. Figure 7.13b demonstrates the use of the mode in the context of a four-bar modal phrase over a CMaj7(♯5) harmony.

The pitch structure of the mode features a characteristic whole-tone segment from 1 to ♯5, which contains two beauty marks: ♯11 and ♯5. The structure of Lydian Augmented also highlights two tetrachords: lower whole tone and upper chromatic. The modal phrase in Figure 7.13b has an interesting rhythmic design. The use of E and D triads in m. 3 adds another level of complexity to the line by implying a 3/8 cross rhythm.



FIGURE 7.13A Lydian Augmented Mode



FIGURE 7.13B Lydian Augmented Phrase





Major Modes—Mixolydian ♯11


In comparison to Lydian Augmented, the Mixolydian ♯11 mode (also known as Lydian Dominant) has a different functional status. Figure 7.14a offers an analysis of its pitch structure, and Figure 7.14b demonstrates the use of Mixolydian ♯11 in the context of a four-bar modal phrase over a C13(♯11) harmony.



FIGURE 7.14A Mixolydian ♯11 Mode



FIGURE 7.14B Mixolydian ♯11 Phrase

The Mixolydian ♯11 mode has a similar pitch architecture to its diatonic counterpart, Mixolydian. The pairing of the beauty marks, ♭7 and ♯11, merges Lydian and Mixolydian characteristics that effectively project the sound of the dominant 7th harmony. The structure of the mode splits into two tetrachords: lower whole tone and upper minor. The phrase in Figure 7.14b projects the extended tertian nature of C13(♯11) through the arpeggiation of D triad in m. 3 and Gmin9(♯7) in mm. 1–2.





Major Modes—Mixolydian ♭13


The pitch structure of Mixolydian ♭l3, shown in Figure 7.15a, is characterized by the presence of two beauty marks: ♭7 and ♭13. Figure 7.15b shows a four-bar modal phrase written over a C9(♭13) harmony with Mixolydian ♭l3 characteristics.



FIGURE 7.15A Mixolydian ♭3 Mode



FIGURE 7.15B Mixolydian ♭13 Phrase

The additional beauty mark, ♭l3, adds a minor quality to the mode. The mode splits into two tetrachords: lower major and upper Phrygian. The arpeggiation of Eø7 in m. 1, A♭Maj7(♯5) in m. 3, and C7 in m. 3 enables a projection of its extended tertian structure—C9(♭13).





Major Modes—Altered


An absolute winner in the category of beauty marks is the Altered mode. Figure 7.16a illustrates the pitch structure of the mode and Figure 7.16b demonstrates its sound in the context of a four-bar modal phrase over a C7alt. harmony.

The Altered mode contains four beauty marks: ♭9, ♯9, ♯11 (♭5), and ♭l3 (♯5). Depending on their position within a chord, the extensions, ♯11th and ♭l3th, can also function as pitch alterations of the perfect fifth, ♭5th and ♯5th. The labeling of these pitches in the Altered mode indicates that they are “shades” of the diatonic fifth just as the chromatic extensions, ♭9th and ♯9th, are “shades” of the diatonic ninth. The mode highlights two tetrachords: lower chromatic and upper whole tone. The saturation of chromaticism in the phrase is quite overwhelming to the point that, without the root of C7alt. reminding us what the harmonic context is, it is difficult to hear this phrase in context.



FIGURE 7.16A Altered Mode



FIGURE 7.16A Altered Phrase

Chromaticism affects all aspects of the musical fabric including harmony, melody, counterpoint, and even tonality. The use of chromaticism varies from slight surface inflections added to a single pitch to more substantial transformations of the tonal structure. Within that huge range of linear and harmonic possibilities, chromaticism is an important musical force with an inextinguishable potential. The addition of chromaticism alters the structure of harmonic formations and even redefines their functional status. Because chromaticism is such a potent force in music, it needs to be treated with caution. In short, the rule “less is more” should be at the forefront of our minds. The effective use of chromaticism depends on a solid sense of time and good voice-leading skills. Chromatic notes that are foreign to the diatonic framework require correct preparation and resolution. Since the preparation and resolution of chromatic notes are inherently rhythmic, the voice-leading forces that control them have important rhythmic as well as melodic implications. The intimate relationship between chromaticism and rhythm implies that, if we try to understand the former without considering its impact on meter and rhythm, our understanding will be incomplete.

In modal jazz theory, there are 14 modes: seven diatonic and seven chromatic. Modes in modal jazz typically function as independent scalar formations that are devoid of traditional tonal relationships. For instance, a complete section of a tune might feature only a single modal scale (e.g. John Coltrane’s “Impressions” or McCoy Tyner’s “Passion Dance”).5 In tonal jazz, however, modes exhibit similar functional behaviors comparable to those of four-, five-, or larger-part structures. In Chapter 8, diatonic and chromatic modes will be combined and their tonal functional associations shown.

NOTES



* * *



1. Scale degree four, however, is needed to give the Ionian mode identity, too. (Not major, in a tonal sense, but Ionian in a modal sense.)

2. This mode was not considered a mode in the Middle Ages and Renaissance because of the tritone between 1 and ♭5 and the occurrence of the diminished triad on 1.

3. For the sake of readability, we will refer to ♯ and ♯ as 6 and 7.

4. This mode is also known as Locrian ♯2 or Super-Locrian.

5. Keith Waters in The Studio Recordings of the Miles Davis Quintet, 1965–68 acknowledges the complexity of the term “modal jazz” and succinctly summarizes the prevailing views on the subject in six points:

“(1) Modal scales for improvisation (or as a source for accompaniment); (2) Slow harmonic rhythm (single chord for 4, 8, 16, or more bars); (3) Pedal point harmonies (local bass pitch or shifting harmonies over a primary bass pitch); (4) Absence or limited use of functional harmonic progressions (such as V–I or ii–V–I) in accompaniment of improvisation; (5) Harmonies characteristic of jazz after 1969 (Suspended fourth—”sus”—chords, slash chords, harmonies named for modes: i.e. phrygian, aeolian harmonies); and (6) Prominent use of melodic and/or harmonic perfect fourths” (p. 46).

OBJECTIVES OF CHORD–SCALE THEORY




* * *



In jazz, the relationship between chords and scales is explained using chord–scale theory. Chord–scale theory relates certain harmonies to melodies and melodies to harmonies. It also illustrates what kinds of harmony and chord progression can be derived from particular scales or modes. The terms “scale” and “mode” will be used interchangeably. By extension, chord–scale theory measures the harmonic identity of improvised lines and examines melodies for their harmonic clarity. Finally, chord–scale theory allows us to formulate rules of voice leading that govern the behavior of harmonic progressions and melodic lines. In short, the relationship between scales and chords can be summarized with the following statement: any melodic line can be represented by a chord and/or harmonic progression and, conversely, any chord or harmonic progression can be horizontalized with a melodic line.

Since we will combine four- and five-part chords (as well as triads and extended tertian sonorities) that add up to some 49 harmonic formations, chord–scale relationships will involve many-to-one ratios. This means that certain scales can accommodate more than a single chord and certain chords can establish a chord–scale relationship with more than a single mode. The possibility that many chords can form a relationship with a single scale is of great importance to the improviser. A proper understanding of this relationship can influence our decisions in finding the most fitting harmonic match for a single scale or vice versa. Even though certain chords might not contain all the essential notes from a given mode, they can still form a convincing chord–scale relationship with that mode.





CHORD–SCALE RELATIONSHIPS




* * *



A chord built entirely of thirds, so-called tertian formation, has seven notes that can be arranged in the form of a scale.1 The notes within the scale, however, have very different melodic and harmonic behaviors. Any vertical or linear combination of notes derived from the scale has the potential to convey the sound of that scale. In order to express such a sound, the selection of pitches in a chord has to be very specific. Figure 8.1 illustrates a chord–scale relationship between CMaj13(♯11) and the Lydian mode.

There are two ways of explaining the chord–scale relationship between CMaj13(♯11) and Lydian. First, an extended tertian structure, CMaj13(♯11), can be horizontalized as the Lydian mode. Second, Lydian can be verticalized as the CMaj13(♯11) harmony. To project the Lydian sound, however, we do not necessarily need a complete seven-note chord; as few as three pitches, major 3rd, major 7th, and ♯11th (or ♭5th), may be used. The relationship between CMaj13(♯11) and Lydian means that the vertical and horizontal dimensions exhibit the same voice-leading behaviors and one can be used to represent and/or complement the other. Just as the structure of CMaj13(♯11) is representative of Lydian, so is the structure of other chords representative of other scales. Figure 8.2 represents the CMaj13(♯11) chord as a melodic phrase with characteristic modal features.



FIGURE 8.1 CMaj13(♯11) and Lydian Mode



FIGURE 8.2 Lydian Phrase

In this figure, the Lydian mode has a very distinct sound. The melodic line prioritizes chord tones and the beauty mark ♯11th, avoids a perfect 5th, highlights a major triad on D, and uses successive fourths at the end of the phrase. The bottom stave projects the Lydian sound through the use of quartal harmonies or structures (that is, chords built in stacked fourths). These contain the most active notes derived from the Lydian mode. The interplay between the melodic line and the underlying harmonies unifies both musical dimensions. Not only does chord–scale theory control the relationship between lines and chords, but it also suggests a particular melodic and harmonic vocabulary derived from the structure of specific chords and scales.





Major Category


Possible Harmonic Function—Tonic and Predominant

In the forthcoming discussion, modes and chords are placed in the familiar functional categories. Each figure provides an analysis of the mode’s pitch content in terms of chord tones and extensions along with a selection of chords and upper structures. The term “upper structure” refers to a triad or four-part chord that contains extensions or chord tones (excluding the root) of an extended harmonic formation.

The major category includes three scales: Ionian, Lydian, and Lydian Augmented. They establish a chord–scale relationship with different types of major chord. Figure 8.3 illustrates the pitch structure of these modes along with the corresponding chords.

Note that in the Ionian mode, the 6, Maj7, 6/9, Maj9, and CMaj13 chords include the most important chord tones and extensions from the scale. The six-part CMaj13 is an example of the so-called gapped formation. Gapped formations interrupt the underlying pattern of introducing pitches from the scale in order to prevent excessive doubling. This creates more interesting voicings, or–as is the case in this example–avoids a note that does not fit the content of a fully extended chord. Two triads, major on 5 and minor on 3, summarize the chord–scale relationship using limited harmonic means. Scale degree four is typically employed as a metrically unstressed passing or neighbor tone. In more advanced harmonic settings, however, the avoid note can also participate in the projection of a mode. For instance, harmonic structures such as C(add4) or CMaj7(add4) convey the sound of Ionian, but these structures require a different set of voice-leading rules and specific voicings to make them sound convincing.



FIGURE 8.3 Major Category

In Lydian, the ♯11th is a pitch that flavors the mode in a highly recognizable manner. The chord–scale relationship in Lydian illustrates one of many spelling discrepancies that we will try to untangle. The ♯11th functions as an extension in extended tertian formations, such as in CMaj13(♯11). The ♯11th, then, assumes the presence of the perfect 5th. In four-and five-part chords such as CMaj7(♭5) and CMaj9(♭5), the alternate spelling ♭5th is used for the same pitch in order to preserve the tertian nature of their respective structures. A major upper-structure triad on 2 and a minor upper-structure triad on 7 convey the character of the Lydian collection using limited harmonic means.

In Lydian Augmented, the ♯5 is a pitch that injects the characteristic augmented sound into the framework of the mode or chords. The Maj7(♯5) and Maj9(♯5) chords delineate the sound of the scale. The most common triad within this mode is the one built on 3 and has a major quality. The major 13th functions as an extension in the context of a complete tertian formation, as in . Otherwise it functions as a passing or neighbor tone.





Minor Category


Possible Harmonic Function—Tonic and Predominant

The minor category includes three modes: Melodic Minor, Aeolian, and Dorian. Figure 8.4 establishes a chord–scale relationship for this category.

The first four chords, min6, min(♯7), min6/9, and min9(♯7) constitute the familiar four- and five-part formations and form a strong chord–scale relationship with Melodic Minor. The remaining ones, min11(♯7) and min13(♯7), feature extended tertian structures that incorporate six and seven notes from the scale, respectively. A major upper-structure triad on 5 captures the sound of Melodic Minor using limited triadic means.

Similarly, all the notes from the Aeolian mode can be implemented in a chord. Among the four formations from Figure 8.4, the min9(♭6) and min11(♭13) chords admit both the chord tones and the beauty mark into their structure. The first two, min7 and min9, can represent the scale too, provided that the beauty mark occurs somewhere in the melodic line. In this particular context, the min7 and min9 chords assume the presence of ♭6th or ♭13th in the melodic dimension. The complementary relationship between chords and lines constitutes an important feature of chord–scale theory.

The Dorian mode is an interesting collection with equally interesting chord–scale relationships. The dual harmonic function of Dorian–tonic and predominant–slightly complicates these relationships. The Dorian mode is a symmetrical scale that features two adjacent minor tetrachords. In theory, Dorian can admit all the notes from the scale into the structure of a chord. In practice, though, the selection of notes for a melodic line or a chord is entirely predicated on the context in which the Dorian mode appears. All the chords from Figure 8.4 establish a chord–scale relationship with Dorian and can potentially function as tonic formations. Yet, only min7, min9, and min11 function exclusively as predominant chords. Therefore, the role of the beauty mark decreases in predominant-type chords and increases in tonic formations. We can also emphasize these two different functional associations of Dorian by using specific upper-structure triads. In the tonic formation, we can use a minor triad on 2; in the predominant Dorian, a major triad on ♭7.



FIGURE 8.4 Minor Category

Dorian as Tonic and Predominant

Compare the sound of the two melodic phrases in Figures 8.5a and 8.5b.

The pitch content of these two phrases is derived exclusively from the Dorian mode. In Figure 8.5a, the line features successive fourths and prioritizes the beauty mark, major 6. The parallel quartal structures reinforce the melodic line and use the interval of a fourth as a basic building block. This particular pitch and harmonic architecture implies a modal style of improvisation. In Figure 8.5b, the phrase exhibits very different intervallic characteristics. The use of the minor 7th completely overshadows the major 6th, which becomes de-emphasized as an unaccented passing tone at the “and” of beat 2 in m. 2. The intervallic design of the melody highlights stacked thirds; these are complemented by mostly tertian formations and/or guide tones. In this context, the use of Dorian implies a more traditional style of improvisation, which we might implement over a predominant ii7 in the ii7–V7–Imaj7 progression.



FIGURE 8.5A Dorian as a Tonic



FIGURE 8.5B Dorian as a Predominant

What can chord–scale theory tell us about the two phrases from Figures 8.5a and 8.5b? First, it tells us that the scale is a powerful entity that can exhibit either modal or tonal characteristics. Second, the intervallic design of melodic lines can potentially suggest modal or tonal environments. Third, the mode provides a structural foundation for melody and harmony. Fourth, in modal environments, upper melodic extensions function primarily as independent chord members that are not bound by the same rules of voice leading as their analogous counterparts in the tonal environment. Fifth, the pitch content of melodic lines can be effectively manipulated by exploring modal and tonal characteristics of scales.





Dominant Category


Possible Harmonic Function—Dominant

The dominant category establishes an intricate family of chord–scale relationships. The dominant category includes four scales: Mixolydian, Mixolydian ♯11, Mixolydian ♭13, and Altered. Figure 8.6 illustrates a chord–scale relationship between dominant modes and corresponding chords.

The only pitch to be avoided is 4. All other notes can freely participate in a chord to project the sound of these dominant-functioning collections. When examining the content of the dominant 7th, 9th, and 13th chords, notice that their pitch content captures the diatonic qualities of the Mixolydian mode. The sound of Mixolydian can also be expressed using two minor upper-structure triads on 5 and 6.



FIGURE 8.6 Dominant Category

The pitch structure of the Mixolydian ♯11 mode approximates the distribution of partials in the overtone series.2 Figure 8.7 illustrates the overtone series, which distributes partials or overtones above the fundamental note, C1. The overtone series illustrates the sonic architecture of fundamental notes as they occur in nature. The distribution of partials above the fundamental note correlates with the location of chord tones and extensions within chords. Those closer to the fundamental (5ths, 3rds, and 7ths) form chord tones, those further removed from the fundamental (9ths, 11ths, and 13ths) constitute chordal extensions.



FIGURE 8.7 The Overtone Series

The Mixolydian ♭13 mode establishes a chord–scale relationship with the dom7(♯5), dom9(♯5), and dom9(♭13) chords. The mode is typically used in the context of dominant chords occurring in minor keys. Because of the potential spelling discrepancies that might arise in certain chord progressions involving a dom9(♯5) chord, we will implement the syntactically correct dom9(♭13). In the key of C minor, for instance, the ♯5th in G9(♯5) indicates D♯, which does not exist. Although the G9(♯5) spelling preserves the tertian nature of the chord, by referring to ♯5th as ♭13th we avoid making a syntactical error, which is all the more serious because it affects the minor 3rd of the tonic chord, E♭. In addition, the pitch alteration ♯5th becomes the chromatic extension ♭13th in the context of an extended tertian formation, such as a gapped C9(♭13) in Figure 8.6, which includes a perfect 5th as a chord tone.

Even though the dom7(♭5) and dom7(♯5) chords form a relationship with the Altered mode, without the essential chromatic extensions, the Mixolydian ♯11 or Mixolydian ♭13 scales may actually be implied. The five-part chords that establish a chord–scale relationship with the Altered mode in Figure 8.6 have a highly chromatic pitch content and the degree of tension increases with the addition of the ♯9th. There are two major triads (♭5 and ♭6) and two minor triads (♭2 and ♭3) that project the sound of the Altered mode.

In the case of chromatic chords and modes (or even with certain diatonic formations and scales), the issue of providing a unified methodology for labeling extensions is extremely problematic. As we have observed, extensions can be labeled as pitch alterations and pitch alterations as extensions. Attempting to resolve these discrepancies should give us a good opportunity to think more rigorously about the choice of notation and the implications of those choices.





Suspended Dominant Category


Possible Harmonic Function—Dominant, Predominant, Tonic

In the suspended dominant category there are four modes: Mixolydian, Mixolydian ♭13, Phrygian, and Dorian ♭2. They establish chord–scale relationships with different types of chord: triads, four-, five-, and six-part. The 7sus chord can function as dominant, predominant, or even as tonic in certain types of modal tune.3 Chord–scale theory for this category is rather complex because the 7sus chord can assume different harmonic functions. For instance, a chord–scale relationship with Phrygian and/or Dorian ♭2 might seem problematic because the major 3rd is not even present in the pitch structure of these modes. We can actually remedy this situation by reinterpreting ♭3 as ♯9th. And since the 7sus chord includes a perfect 4th as an essential chord tone, the absence of the major 3rd from those modes is not too problematic.

Figure 8.8 illustrates chord–scale relationships for this category.



FIGURE 8.8 Suspended Dominant Category

A major triad on ♭7 and a minor triad on 2 are often used to represent the sound of the suspended Mixolydian mode. The Mixolydian ♭13 scale establishes a chord–scale relationship with two chords, dom9(♯5)sus and dom7(♭13)sus, both of which contain a dominant 7th chord on ♭7. In the former, the ♯5th replaces the 5th; in the latter, the ♭13th implies the 5th.

Chords that establish a relationship with the Phrygian mode have an interesting selection of upper structures that can be superimposed over the root of the chord. The 7(♭9)sus chord contains a root position half-diminished 7th chord on 5 (G–B♭–D♭–F); includes an enharmonically spelled root position min7 chord on ♭7 (B♭–D♭–F–G♯); dom7(♯9)sus superimposes an enharmonic major triad with an added major 2nd on ♭3 (D♯–F–G–B♭); and incorporates an enharmonically spelled major tetrachord on ♭3 (D♯–F–G–A♭). The Dorian ♭2 scale forms a chord–scale relationship with the following formations: dom7(♭9)sus, dom13(♭9)sus, dom7(♯9)sus, and dom13(♯9)sus. One of the most effective upper structures that can represent the sound of Dorian ♭2 is an augmented triad on ♭2 over the chordal root.

When comparing the chord–scale relationship between Phrygian and Dorian ♭2 in Figure 8.8, notice that the dom7(♭9)sus and dom7(♯9)sus chords establish a relationship with both modes. Neither of these chords, however, contains a note that is essential to the corresponding modes: the dom7(♭9)sus and dom7(♯9)sus chords in Phrygian do not include ♭6, while the dom7(♭9)sus and dom7(♯9)sus chords in Dorian ♭2 do not include major 6. As was the case with other chords that almost captured the sound of particular modes, the missing note from the chord needs to be supplied by the melodic line or assumed aurally. Based on this mutual relationship, we can formulate a basic premise that underlies chord–scale theory: in order to establish the relationship between chords and scales, both musical forces–horizontal and vertical–have to complement and interact with each other in time.





Intermediary Category


Possible Harmonic Function—Predominant and Dominant

The intermediary category contains three modes: Dorian, Locrian, and Locrian ♮2. They establish a chord–scale relationship with min7 and min7(♭5), as well as with other extended formations. In discussing chord–scale theory for this category, we will focus on establishing a relationship between the min7 and min7(♭5) chords, and with the corresponding scales. Since these chords are frequently used in the ii7–V7–Imaj7 and progressions, respectively, choosing the correct scale is essential in projecting the sound of these harmonies during improvisation. Figure 8.9 illustrates a chord–scale relationship between intermediary-type modes and corresponding chords.

The Dorian mode establishes a relationship with the min7 and min9 chords in order to convey the sound of predominant ii7 in the ii7–V7–Imaj7 progression. In our earlier discussion of Dorian, we observed that all the notes from the scale could participate in projecting the Dorian sound. Here, the issue of the avoid note comes back and relates to the status of the beauty mark. The major 6th is excluded from the structure of predominant formations and, in the context of melodic lines, should be treated as a passing or neighbor note.



FIGURE 8.9 Intermediary Category



In Figure 8.9, the chromatic Locrian ♮2 is located before the diatonic Locrian. The Locrian ♮2 mode includes a major 9th, the most suitable form of the 9th that can be added to the min9(♭5) chord. We can also use upper structures: min(♯7) on ♭3, Maj7(♯5) on ♭5, and the augmented triad on ♭5, to convey the sound of Locrian ♮2. The min7(♭5) chord in Figure 8.9 also forms a chord-scale relationship with the diatonic Locrian mode. This scale can be used with the min7(♭5) chord, but the beauty mark ♭2 is de-emphasized and treated as a passing or neighbor note.4 The other beauty mark, ♭5, functions as a chord tone and is integral to the sound of both Locrian scales.

Chord-scale theory tells us which notes to use in melodic lines, which chords best represent the harmonic character of those lines, and which combinations of notes can participate in a chord voicing. But, the chords we use cannot always accommodate all the notes from corresponding scales. In instances when a chord does not clearly project the sound of a mode, the corresponding melodic line has to supply the missing notes from the correct scale. Depending on the context, however, even the most important notes from the mode, such as beauty marks and chord tones, might be de-emphasized and treated as passing or neighbor notes.





THE II7–V7–Imaj7 PROGRESSION




* * *



Figure 8.10 illustrates the chord–scale relationship for the ii7–V7–Imaj7 progression in the key of C major.

Even though all the notes from Figure 8.10 are derived exclusively from the C major scale, the individual modes establish a strong metric relationship with the underlying chords. Notice that downbeats in Figure 8.10 are occupied by chord tones, while offbeats with passing notes are notated with small note heads. Such a distribution of notes enables a clear projection of chords and harmonic progressions during improvisation.

In addition to the diatonic relationship shown in Figure 8.10, we can also experiment with substitute chords and their corresponding scales in order to establish more intricate chord–scale relationships, such as those provided in Figure 8.11. While these relationships expand our melodic vocabulary and harmonic understanding, they also illustrate how to introduce chromatic notes. Figure 8.11 illustrates some of the most common combinations of chromatic chord–scale relationships for the ii7–V7–Imaj7 progression.

In Figure 8.11a, the dominant chord in m. 2 includes the ♯11th, which establishes a chord–scale relationship with the Mixolydian ♯11 scale. The tonic in mm. 2–3 features a Maj7(♯11) chord, which forms a chord–scale relationship with the Lydian mode. The remaining progressions in Figure 8.11 illustrate ever more complex chord–scale relationships. In Figure 8.11d, for instance, the use of the secondary dominant 7th, V7/V, in m. 1 transforms the diatonic ii7–V7–Imaj7 progression into the chromatic II7–V7–Imaj7. The use of Mixolydian ♯11 over the secondary dominant 7th is specially common in Bebop improvisation.

FIGURE 8.11 Chromatic Chord–Scale Relationships





THE PROGRESSION




* * *



Figure 8.12 illustrates two chord–scale relationships for the progression in the key of C minor.

In Figure 8.12a, the Locrian ♮2 mode establishes a chord–scale relationship with Dmin7(♭5) as it contains a major 9th that expands the min7(♭5) into the min9(♭5) formation. The choice of Mixolydian ♭13 also fits the underlying tonal context since ♭13th anticipates the arrival of minor 3rd of Cmin7. Figure 8.12b proposes one of many chromatic chord–scale relationships that can be established for the progression. Here, the chromaticism becomes more prominent as the dominant 7th chord forms a chord–scale relationship with the Altered scale and the tonic chord with Melodic Minor.

One of the goals of chord–scale theory is to develop our practical skills. Although Figures 8.11 and 8.12 showed different chord–scale relationships, our choices in our improvisations should reflect the surrounding musical context. Even though Mixolydian ♭13 is considered a chromatic mode in the context of the progression from Figure 8.12a, it is a more fitting choice than the diatonic Mixolydian because it contains the ♭13th that better conveys the underlying tonality. The treatment of chromatic extensions is an important factor to consider while making improvisational choices. In Figure 8.11b, for instance, the Altered mode over the dominant 7th prepares the arrival of Lydian Augmented. Since Lydian Augmented contains a dissonant ♯5th, the Altered mode one measure earlier foreshadows the occurrence of this alteration.



FIGURE 8.12 Chord–Scale Relationship:

NOTES



* * *



1. Tertian formations complete their third span after two octaves and may contain different kinds of 3rds (minor, major, diminished, and augmented).

2. The Mixolydian ♯11 mode is also known as the “overtone” or “acoustic” scale due to its relation to the overtone series.

3. “Yes or No,” “Little One,” “Milestones,” or “Litha,” for instance.

4. In more advanced harmonic settings, however, a ♭9th can be added to the min7(♭5) chord, as can be seen in Figure 25.6.

GENERIC BLUES




* * *



The blues is an American art form. Originally, blues were primarily sung, with one of the objectives being to tell a story as vividly as possible. To tell stories, blues singers used simple repeated phrases charged with a variety of expressive devices. The ability to tell the story from one’s perspective came to represent blues performance practice in particular, and jazz improvisation in general. The familiar saying that “your solo should tell a story” takes on a completely different meaning when we consider whence it came and how intricate life’s stories can really be. Early blues practitioners were unconstrained by the form of the blues as the duration of improvised lyrics often influenced the length of individual phrases. Eventually, the blues was codified as a 12-bar form and, as such, it is by far the most common among jazz musicians.

Figure 9.1 illustrates a fundamental harmonic framework of the 12-bar blues that we will refer to as a generic blues.



FIGURE 9.1 Generic Blues

The form of the generic blues can be partitioned into three four-bar phrases labeled as AA`B. Each of these four-bar phrases receives different harmonic support: the A phrase (mm. 1–4) is on the tonic, the A` (mm. 5–8) begins on the predominant and ends on the tonic, and the B phrase (mm. 9–12) begins on the dominant and ends on the tonic. Even though each phrase is analyzed with traditional functional labels, the underlying chords do not behave as specified by these labels. For instance, the tonic chord in m. 1 and the subdominant chord in m. 5 employ dominant 7th chords. In the generic blues, then, the chords on , , and have the dominant 7th quality.

The labels A and A` imply the same melodic content whereas the label B implies the use of new melodic material. The predominant harmonic support in mm. 5–6 of the A` phrase, however, completely redefines the relationship between melody and harmony. The same melodic idea–which in the first A section might be heard as tonally stable–sounds unstable in the second A` section due to the disagreement between melody and harmony. In the lyrics of early blues performances, the first two lines (A and A`) frequently introduce a problem, pose a question, or depict a specific situation. The third line (B) almost always provides a solution to those circumstances.





TELLING A STORY




* * *



Here is a sample of blues poetry from the iconic “Backwater Blues”:

Then they rowed a little boat about five miles ’cross the pond

Then they rowed a little boat about five miles ’cross the pond

I packed all my clothes, throwed them in and they rowed me along.

Figure 9.2 demonstrates a musical realization of this story.

The line in mm. 1–2 has a strong rhythmic and melodic profile. The predominant harmonic support in mm. 5–6 for the same melodic idea from mm. 1–2 redefines the relationship between melody and harmony. For instance, the A♭4s on beat 2 in m. 5 and on beat 4 in m. 6 form the interval of a perfect 4th with the chordal root; this creates melodic and harmonic tensions with the underlying E♭7 chord. The B phrase in mm. 9–10 resolves the accrued tension by introducing a new melodic idea. The musical answer in mm. 9–10 has a balanced melodic design that effectively complements the content of the A phrase.



FIGURE 9.2 Musical Realization of a Story





CALL AND RESPONSE




* * *



The musical depiction of the lyrics from Figure 9.2 illustrates an additional aspect of blues performance practice–the use of call and response. Originally practiced by a large group of people, this improvisational technique involves sharing ideas between the leader and her/his followers. Mastering the call and response technique is especially important at the beginning of our encounter with jazz improvisation. It engages us in a meaningful dialogue that includes exchanging and communicating musical ideas. The communicative aspect of call and response is relatively straightforward in the context of verbal conversation. In a musical setting, however, when spoken words and sentences are replaced with motifs and melodic phrases, the structure of the call and response might not be as obvious. To be a good communicator, we have to know how to listen, pay close attention to what the other musicians are playing, and try to be receptive to their ideas.

In certain scenarios, however, the use of call and response technique might create less than desirable effects. For instance, when the call and response takes the form of exact and immediate repetition, it might be impressive but not necessarily in keeping with the surrounding musical context. A much more subtle way of thinking about the call and response technique involves musical interaction at the level of the entire performance in which non-adjacent sections relate to one another, and where the flow of the performance is regulated by logically introduced musical ideas. In creating a musical narrative, then, we can also respond to each other’s playing, but these responses are not as obvious as simple repetitions tend to be. We can demonstrate our listening skills, for instance, by incorporating an idea that we have previously heard (i.e. a rhythmic motive from the drummer, or a melodic gesture from the guitarist) and develop it in such a way that leads to a more satisfying musical discourse. The call and response aspect of improvisation means that musicians understand each other’s intentions, have an unspoken agreement, so to speak, and project them with a high level of personal expression and musical commitment.





THE BLUES SCALE




* * *



The expressiveness of the blues comes from the melodic inflections added to particular notes. When we listen to various vocal or guitar renditions of the blues, these inflections are easily recognizable; they stand out because of their emotional charge and slightly “out of tune” sound.1 The so-called blues scale approximates the sound of these pitch inflections by altering , , and of the major scale. Figure 9.3 illustrates the content of the blues scale and its derivation from the major scale.

The blues scale is a six-note collection with the “blue” notes on ♭3, ♭5, and ♭7. Although the presence of ♭7th suggests a chord–scale relationship with the dominant 7th chord, the use of the blues scale is not limited to this chord only. In the context of the blues scale, the pitches ♭3 and ♭5 constitute expressive embellishments not bound by any particular harmonic function or chord type. The blues scale, then, is an androgynous collection that works just as well for dominant 7ths as it does for tonic and predominant chords. The unspecified functional associations of the blues scale suggest that this collection is relatively easy to implement during improvisation. Indeed, the blues scale not only allows us to add expression to our playing, but it also demonstrates our understanding of its historical importance and its role in the jazz tradition.



FIGURE 9.3 Blues Scale





Major Blues


Having examined the structure of the blues scale, we can now explore the tonal potential of the scale.2 Figure 9.4 illustrates the structure of G blues scale.

This scale has a minor feel to it; notice the use of ♭3, ♭5, and ♭7. By starting the scale on B♭3 and continuing through the octave, we are able to generate a major scale that, in addition to having the “blue” 3rd, also contains the major 3rd needed for major and dominant 7th chords. A major blues scale, shown in Figure 9.5, starts on ♭3 of the regular blues scale, contains a perfect 5th, major 6th, and major 9th, and establishes a convincing chord–scale relationship with the B♭6/9, B♭13 or other B♭–based dominant 7th chords.

In addition to more generic usage of the blues scale (where a single scale is used in the context of different chords), we can be more discerning and assign a regular blues scale to minor chords and a major blues scale to major and dominant 7th chords.



FIGURE 9.4 G Blues Scale



FIGURE 9.5 Major Blues Scale





BASIC BLUES PROGRESSION




* * *



In the most fundamental form, the generic blues consists of only three chords: I7, IV7, and V7. These harmonies control the structure of the blues, even though in some chord progressions, particularly those from the Bebop Era, they might be disguised, substituted, transformed, or omitted all together. The generic or three-chord blues, without any additional chord changes, was often employed in early jazz, particularly in Early Blues, Boogie-Woogie, and different New Orleans styles.3 We will now examine the harmonic structure of a slightly modified blues (one that is probably the most common in jazz), and illustrate how this chord progression came about and how it relates to the generic blues. Figure 9.6 illustrates a basic blues progression and its relationship to the generic blues. When jazz musicians gather together to play the blues, the chances are that they are going to use this chord progression.



FIGURE 9.6 Basic Blues Progression

Notice that, in mm. 9–12, the chord changes are different in both progressions. A characteristic V7–IV7 chord succession in the generic blues becomes a ii7–V7–I7 progression in the basic blues. Another noticeable difference between the two progressions relates to the overall unfolding of harmonic rhythm. The slow harmonic rhythm of the generic blues reflects the fixed location of the structural chords: I7 in mm. 1, 7, and 11; IV7 in mm. 5 and 10; V7 in m. 9. In the basic blues, the rate of harmonic rhythm is much faster, usually with one-chord-per-measure changes. Additionally, the mediant harmony VI7 in m. 8 introduces a chromatic chord that anticipates the arrival of a predominant ii7 in m. 9. This tonicizing sonority, V7/ii, offers a momentary departure from the diatonic framework of the blues. In comparison to the generic blues, Figure 9.6 contains more tonally based progressions and, as such, lends itself to improvisation, something that we will undertake in Chapter 10.





Keyboard Realization


In addition to being fluent on our primary instruments, the ability to realize chord progressions on the piano is an essential skill that enables us to understand the harmonic structure of tunes, their voice-leading propensities, and their inherent chord–scale relationships. The most basic realization of the basic blues progression shown in Figure 9.7 involves chordal roots in the left hand (L.H.) and guide tones in the right hand (R.H.).



FIGURE 9.7 Basic Blues: Guide-Tone Realization

The voice leading between adjacent chords is very strict. A major 3rd of the dom7 chord moves by a half step to a minor 7th of another dom7 and, conversely, a minor 7th of the dom7 moves down to a major 3rd. Skips are allowed only when stepwise motion is impossible to implement. For instance, the guide tones of B♭7 and G7 in mm. 7–8 move by parallel minor 3rds because this is the most efficient way to connect these chords. Larger skips can occur in places where the guide tones are registrally too low or too high. These skips or register transfers should coincide with the overall design of phrases, distribution of cadences, and harmonic rhythm of a tune. For instance, register transfers can be made in mm. 5 and 9 because those measures mark the beginning of new phrases and are aligned with the new harmonic functions. In summary, the successful realization of harmonic progressions depends on good voice leading, which primarily relies on stepwise motion between guide tones and careful distribution of skips.





Chord-Scale Relationships


Figure 9.8 establishes a couple of chord–scale relationships for the basic blues progression in the key of B♭. Figure 9.8a uses major and minor blues scales and Figure 9.8b combines blues scales and modes.



FIGURE 9.8 Basic Blues: Blues Scales and Modes





MINOR BLUES




* * *



The progression shown in Figure 9.9 exemplifies the structure of a minor blues.4

The chord structure of the minor blues is characterized by the presence of traditional tonal progressions. For instance, the tonicization of iv in m. 4 uses a secondary dominant 7th, V7/iv, and the motion to V7 in m. 10 is prepared by the ♭VI7 chord. This particular preparation of the dominant 7th, ♭VI7-V7, is one of the harmonic trademarks of the minor blues.





Chord-Scale Relationships


The two chord–scale relationships for the minor blues shown in Figure 9.10 indicate a selection of blues scales and modes that will be explored in Chapter 10.

GETTING STARTED




* * *



In Chapter 2, we stressed that rhythmic integrity and a good sense of time should be the focus of a performance. The quality and placement of swing 8th notes, phrasing, and articulations are essential characteristics of melodic lines. While these characteristics relate to the overall presentation of melodic lines, the content of our phrases is intimately related to the musical material with which we are working. Successful improvisation depends just as much on the ability to project the melodic line in a convincing fashion as it does on a familiarity with the melodic syntax, harmonic vocabulary, and rhythmic conventions associated with the tune being used for improvisation. In addition, the ability to listen to our own playing, articulate the form of improvisations, and make large-scale musical connections is an important skill that can improve improvisational skills.

In our initial attempts at improvisation, we might notice that, instead of concentrating on when to play, we are spending too much time thinking about what to play. This is perfectly understandable; after all, improvisation is a complex musical activity. It requires complete internalization and practical understanding of theoretical concepts. In shifting our focus from what to play to when to play, the what to play needs to be fully internalized. This involves studying different theoretical concepts, learning different styles of improvisation, listening to music, and practicing. Improvisation is similar to learning a new language. The first step involves the acquisition of essential words and grammar rules; these are then combined in simple sentences to enable basic communication. Similarly in jazz improvisation, we first acquire a basic vocabulary of chords, scales, and motifs along with some normative voice-leading rules. Once we have internalized these building blocks and rules, we can create idiomatic improvisations of our own.





BLUES RIFFS




* * *



We begin our study of improvisation with the blues. Improvising on the blues presents an interesting situation because the task might not seem too complicated. After all, we can negotiate different blues progressions with only a blues scale and sound quite convincing. Studying blues improvisation, however, gives us a solid foundation that we can later develop and expand. The most basic strategy in learning blues improvisation involves playing simple melodic ideas derived from the blues scale, called blues riffs. In using this approach, the negotiation of chord changes is not the main concern because blues riffs fit the structure of different chords and chord progressions. There is, however, one important aspect of our playing that requires attention, namely rhythm. Figure 10.1 illustrates a solo on the generic blues form that employs a variety of blues riffs.

These riffs have a characteristic melodic and rhythmic profile that influences the overall flow of the solo. The design of these riffs has a unique pitch structure that prioritizes the use of the blue notes. Figure 10.2 provides a compilation of one- and two-bar blues riffs starting on different pitches of the blues scale that can be explored during improvisation. It is worth noting that these riffs are just as effective in improvising on the blues as they are in improvising on other types of tunes. While improvising on blues progressions, we will use these riffs at different locations within the form so that the phrasing does not follow the regularity of four-bar phrases of the blues in a predictable way.



FIGURE 10.1 Two-Chorus Blues Solo





THE ROLE OF GUIDE TONES




* * *



In Chapter 8, it was noted that harmonies can be represented horizontally as melodic lines and that melodic lines can be represented vertically as harmonic formations. This mutual interrelationship between chords and lines implies that the same rules of voice leading that control the behavior of chords will also control the behavior of melodic lines. The keyboard realization of the blues in Chapter 9 (Figure 9.7) involved placing the guide tones in the R.H. and chordal roots in the L.H. The harmonic guide tones from Figure 9.7 can be horizontalized as a melodic line. This line can literally guide us through the chord changes while improvising, hence the term guide-tone improvisation. The melodic line in Figure 10.3 consists of two half notes (or four quarter notes in m. 4) using 3rds and 7ths from the underlying harmonies. This apparently single-line melody is an example of a compound melody. Figure 10.3 shows the transformation of the vertical guide tones into two horizontal compound melodies beginning on the 3rd and the 7th, respectively, and suggests a chord–scale relationship that can be explored during improvisation. The implied contrapuntal lines are indicated with stems pointed in the same direction and attached to a dashed line.



FIGURE 10.2 Blues Riffs



FIGURE 10.3 Guide-Tone Line: 3rds and 7ths





THE CHARLESTON RHYTHM




* * *



By emphasizing a guide-tone line in our improvisation, we can clearly express the quality and function of underlying chords. To be successful at this type of improvisation, the horizontalized guide tones need to be metrically emphasized. We can begin by activating the line with the help of a two-note rhythmic gesture known as the Charleston rhythm.1 This idiomatic rhythmic idea, along with the eight possible metric locations within the measure, is shown in Figure 10.4.



FIGURE 10.4 The Charleston Rhythm





EXPLORING GUIDE TONES




* * *





Using 3rds and 7ths


The guide-tone line establishes a chord–scale relationship with the underlying harmony that we need to preserve once we move away from improvising solely on a blues scale. Using the chord–scale relationships from Figures 10.3, 9.8, and 9.10, we will now demonstrate how the relationship between guide tones and corresponding scales might work in the context of a solo. In addition to establishing a convincing chord–scale relationship, the solo in Figure 10.5 also employs various incarnations of the Charleston rhythm.





Using 3rds or 7ths


Another approach to practicing guide-tone improvisation involves embellishing only a single guide tone. Melodic activities can be organized either around the 3rd or the 7th of underlying chords. Figure 10.6 illustrates two structural lines of the blues that use the 3rds and the 7ths of corresponding chords, respectively.



FIGURE 10.5 Guide-Tone Improvisation

With a single guide tone the structural line becomes more angular, thereby making its elaboration more challenging. Figures 10.7a and 10.7b demonstrate how to integrate individual guide tones within the context of a solo. Figure 10.7a prioritizes the 3rds and Figure 10.7b emphasizes the 7ths. Arrows indicate the metric placement of guide tones within the line.





The 3rd and 7th lines


In preparing for improvisation, we can select a single line starting on the 3rd or the 7th and elaborate it with different melodic ideas. Such a line fulfills the rules of voice leading (the 3rd of a chord is retained or moves down by a half step; the 7th of a chord moves down by a half step to the 3rd of the next chord). Figure 10.8a illustrates a structural line (top staff) beginning on the 3rd and its melodic elaboration (bottom staff). Figure 10.8b shows a structural line beginning on the 7th and its subsequent elaboration. Notice the metric distribution of guide tones within these lines.

MOTIVIC DEVELOPMENT




* * *



Techniques of motivic development are innately connected with the art of composition and improvisation. Although these techniques may take many different forms, the underlying premise is to take a small melodic gesture, called a motif, and transform it in a logical, coherent, and musically satisfying manner. The use of motivic development provides structural coherence to improvisation. There are certain characteristics, however, that a motif should have in order to lend itself to musical development. These characteristics include a strong rhythmic profile, an interesting melodic shape, a clear harmonic structure, and a relatively short pitch duration. When examining motifs from jazz or classical literature (compiled in Figure 10.9), special attention should be paid to their strong rhythmic, melodic and harmonic characteristics, and, above all, their succinctness and memorability.

FIGURE 10.8B Improvisation: Embellishing a 7th line



FIGURE 10.9 Motifs From Literature line



With their slow (or non-existent) harmonic rhythm, modal tunes are ideal vehicles for practicing improvisation and implementing different techniques of motivic development. Because the pitch content is fixed, the focus is on playing with a good sense of time and on the development of particular motifs. In the overview of techniques of motivic development, we will first demonstrate how to create a motif that successfully captures the sound of a given mode. Then the traditional techniques of motivic development will be examined, such as repetition, transposition, expansion, interpolation, contraction, fragmentation, and inversion. Finally, we will demonstrate how to implement these techniques in practice.

Broadly speaking, a motif should convey the sound of a specific mode and display a strong melodic and rhythmic profile. Figure 10.10 provides a selection of motifs for diatonic and chromatic modes in C. These will later be used for practicing motivic development with the Play Along DVD.

The pitch content of these motifs clearly projects the sound of corresponding modes, as each motif prioritizes the use of chord tones and beauty marks. The rhythm of each motif is representative of jazz syntax and has strong developmental potential.



FIGURE 10.10 Motifs for Practicing Improvisation





Repetition


The technique of repetition is based on either the exact or the inexact recurrence of the motif. Even though exact repetition might be redundant, occasionally it can be employed for melodic emphasis or for confirming musical ideas. Inexact repetition transforms the original motif using slight melodic and/or rhythmic modifications. These modifications typically involve pitch replacements or minor rhythmic displacements. Exact and inexact repetitions, as well as other motivic techniques, are illustrated in Figure 10.11.





Transposition


The technique of transposition transfers the original motif to a different pitch level. There are two forms of transposition: tonal/modal and real. Tonal/modal transposition preserves the underlying tonality/modality of the motif. Thus, it allows for minor intervallic adjustments to the pitch structure of the original motif. Real transposition preserves the intervallic content of the motif when transposed to a different pitch level. The most obvious consequence of real transposition is the infusion of chromaticism and noticeable departures from the underlying tonal/modal center. With this technique, we can effectively control the ebb and flow of chromaticism and its impact on the music. To create a stark melodic contrast, for instance, we can transpose the motif by an interval that does not keep any notes in common between the original and its repetition. In order to exhibit a more controlled approach to improvisation, we can let the intervallic content of the original motif influence the level of transposition. Furthermore, to demonstrate traces of compositional thinking in our improvisation, we can control the level of transposition by implementing pitches from the original motif as roots of the transposed motifs. All of these possibilities are demonstrated in Figure 10.11.





Expansion and Interpolation


Expansion and interpolation are techniques of motivic development that add new material to the original motif. Expansion adds new melodic content at the end of the motif. Tangentially related to expansions, interpolations transform the original motif by inserting new melodic material in the middle of its structure. Figure 10.11 illustrates the use of these techniques.





Contraction and Fragmentation


Contraction, which typically occurs in the context of longer gestures, shortens the length of the original motif. Subsequently, these shorter melodic cells might undergo the technique of fragmentation, which further allows for development through repetition, transposition, and/or expansion. The technique of fragmentation might be advanced through other means as well. For instance, we can partition the original motif into small melodic cells and, then, combine them using different motivic permutations. Figure 10.11 demonstrates the use of these techniques.





Inversion


The technique of motivic development known as inversion mirrors the intervallic content of the original motif. Just as in transposition, there are two types of inversion: tonal/modal and real. In tonal/modal inversion, the shape of the original motif is inverted in pitch space specific to the particular key or mode. Just as in tonal transposition, this technique usually does not preserve the intervallic content of the original motif. Certain intervallic adjustments of the original motif are required in order to preserve the underlying tonality/modality. In real inversion, the intervallic content of the original motif is preserved and, as a result, chromatic pitches will likely occur. Using inversions in improvisation can be challenging because we have to quickly figure out intervallic inversions of the original motif and implement them in real time. In spite of these challenges, however, the use of inversion is a very powerful technique that can add more control in our playing. Figure 10.11 illustrates the use of two types of inversion, as well as other techniques of motivic development. Notice that the intervallic content of the original motif and its transformations are indicated with integers representing a number of semitones. A “+” and “−” indicate the direction of intervals: ascending and descending, respectively.

WHAT DOES A LEAD SHEET TELL US?




* * *



In order to become a successful jazz musician, one has to learn how to read, interpret, and modify lead sheets. Improvising from a lead sheet is a unique performance skill that jazz musicians cultivate on a daily basis and perfect over a long period of time. Comparable to other shorthand notations from classical music, such as figured bass, tablature, partimento, or others, lead-sheet notation contains just enough essential information to create a complete performance.

A typical jazz lead sheet includes a single-line melody, chord symbols, and lyrics. Lead sheets can be a part of larger compilations of songs known as fake books. They can also exist as individual song folios; these types of lead sheet are probably the most accurate and valuable. Musicians can create their own fake books to play with other musicians and to agree on harmonic changes. Jazz lead sheets from reputable publishers contain relatively few mistakes. This is helpful since in the not-so-distant past, illegal fake books contained many mistakes. Reputable publishers sometimes incorporate dubious editorial decisions and present a certain historical performance as somehow iconic of that song's performance practice. Although the accuracy of fake books has certainly improved, the best method of learning and retaining tunes is to find the original recording and transcribe the melody and chord changes from the record.

Songs that constitute the core of jazz repertory were once considered widely popular. They were continually heard on the radio and often topped the charts. Artists who performed them were treated like celebrities and had cult-like followings. Jazz musicians have appropriated these tunes into their repertoire for obvious reasons: they are great songs written by composers who, above all, valued and understood the importance of a good melody. Their popularity among jazz musicians is probably the best testimony that great music never loses its appeal. The original chord progressions of standard tunes might include the harmonic vocabulary typical of the popular idiom during the Golden Age of the American Popular Song, ca. 1900–1950.1 Just as in decades past when jazz musicians offered personal interpretations of these tunes, it is important to learn how to interpret lead sheets in a manner that convincingly expresses the nature, affect, and “feel” of the song.





TWO-LEVEL ANALYSIS




* * *



A method of analysis known as two-level analysis enables us to differentiate between chords that are structurally important and those that are not. In this method, the second level is more general. It stands back from surface-level details to examine larger harmonic gestures and functions. It also determines the large-scale key distribution and the harmonic character of individual phrases. Such examination forces one to look at the tune from a more global perspective. The first level of analysis goes back to a chord-by-chord, measure-by-measure unfolding of harmonic changes. In conjunction with the initial observations, it helps to determine how chords interact with one another, how progressions project harmonic function, and how chords behave on a local level. This analytical method establishes a hierarchical relationship between chords, illustrates the functional relationships at the phrase level, and explains how the tonality of a tune works. It merges global and local perspectives into a unified analytical synthesis.





“MY ROMANCE”




* * *



This analytical demonstration discusses the difference between chords that are structurally important and those that are not. Figure 11.1 illustrates a lead sheet of “My Romance” by Richard Rodgers and Lorenz Hart.2



FIGURE 11.1 Lead Sheet—“My Romance”


Figure 11.2 provides a two-level analysis of “My Romance” (mm. 1–16). The A section is divided into two four-bar phrases. The first phrase begins on the tonic and features a strong cadential confirmation of the tonic in m. 4 that establishes the key of the song. Remember that to establish a key it is necessary to have a statement of the tonic, a motion away from the tonic, and some kind of cadential gesture to confirm the tonic. In standard tunes, that cadential gesture almost exclusively takes the form of the ii7–V7–Imaj7 progression. Measures 1–4 of “My Romance” exhibit these characteristics, as indicated by Roman numerals. The second phrase in mm. 5–8 begins on the submediant and leads back to the tonic.

Even though the harmonic rhythm is relatively fast, with two chords per measure, not all the chords have the same structural and functional weight. For instance, mm. 1–2 expand the underlying tonic with a Imaj7–IVmaj7–iii7–vi7 progression, whereas mm. 5–6 expand the submediant with a local i7–V7–i7 progression before tonicizing the predominant ii7 with a V7/ii on beat 3 in m. 6. The second level of analysis, however, reveals a simpler and more fundamental tonal architecture for the A section: mm. 1–4 establish the tonic with a Imaj7–ii7–V7 tonic expansion; mm. 5–6 feature tonal motion to the submediant followed by a ii7–V7 confirmation of the tonic in mm. 7–8. These harmonies occur on metrically strong positions and, by and large, reflect the symmetrical nature of eight-bar phrases.

The B section features a harmonic departure away from the tonic. In particular, mm. 9–13 are controlled by a IVmaj7–Imaj7 progression with local blues inflections highlighting the ♭VII7 harmony. The ♭VII7 chord in mm. 9 and 11 is also known as a back-door dominant 7th because it subsumes its natural voice-leading tendencies and deceptively resolves up a whole step to the tonic chord. The music departs even further away from the main key in the second four-bar phrase of the B section. To make tonal sense out of that progression, let's start in m. 16 and move backwards. The B section is harmonically open and ends on the dominant in m. 16. That dominant 7th is reached through a sequence of fifth-related chords that begins on F♯min7(♭5) in m. 13. Each measure, with the exception of m. 15, contains some kind of a ii7–V7 progression. The second level of analysis indicates a more fundamental harmonic architecture of the B section: mm. 9–12 elaborate a diatonic IVmaj7–Imaj7 progression; mm. 13–16 then expand the underlying tonality with chromatic motion to the mediant and a subsequent return, via a cycle of fifth progression, to the dominant.

By looking at the overall tonal architecture of a tune, it is possible to learn and memorize the essential harmonies in the first half of the tune. In fact, if a seasoned jazz musician were to explain the harmonic progression of mm. 1–16 to a novice, he would probably say something like this:

The first A section has two four-bar phrases: the first in I, the second in vi, which returns back to I. The B section features a IVmaj7–Imaj7 progression with a backdoor ♭VII7 in the first four-bar phrase, and a cycle of fifths with local ii7–V7s starting on , in the second four-bar phrase that closes on the dominant 7th.

Notice that this succinct explanation omits a lot of harmonic details and focuses instead on a big tonal picture. The harmonic details absent from that description are either theoretically assumed or aurally picked up during the performance.



FIGURE 11.2 Two-Level Analysis—“My Romance,” mm. 1–16





“ALL THE THINGS YOU ARE”




* * *



This analysis focuses on only one aspect of the tune, namely the presence and function of the ii7–V7–Imaj7 progression. Figure 11.3 shows a lead sheet of “All the Things You Are” by Jerome Kern and Oscar Hammerstein II. With a beautiful melody, gorgeous lyrics, interesting harmonic progressions, and an extended 36-bar AABA form, “All the Things You Are” has become an ultimate favorite among jazz musicians.3

What is particularly striking about “All the Things You Are”—and about the majority of standard tunes as well—is the sheer number of ii7–V7–Imaj7s permeating its harmonic structure.4 In standard tunes, the two basic types of the ii7–V7–Imaj7 progression are commonly implemented: structural and tonicizing. The structural ii7–V7–Imaj7 may or may not always be present at the outset of a tune, but will definitely occur at the end of it in order to confirm the underlying tonality. In “All the Things You Are,” mm. 33–36 feature a clear statement of the structural ii7–V7–Imaj7. The same progression also occurs in mm. 2–4, but in this context it provides a harmonic support for the melody and is a part of the larger harmonic span. The structural weight of both progressions is very different and depends on their placement within the tune.



FIGURE 11.3 Lead Sheet—“All the Things You Are”


The tonicizing ii7–V7–Imaj7 progression functions as a local cadential preparation and/or confirmation of secondary key areas. In mm. 6–8, a local (ii7–V7)/III tonicizes the mediant key, III. Why the mediant key? Because the tune appears to be in the key of A♭ major and any harmonic departure from the main tonic is labeled accordingly. This tonicizing progression also occurs within a phrase and, as such, plays a purely supportive role. Remember that the tonicizing ii7–V7 is placed in parenthesis, followed by the diagonal slash and a Roman numeral that indicates a tonicized key area, hence the (ii7–V7)/III label in m. 6. At the end of the second A section, there is another local ii7–V7 progression tonicizing the leading-tone key, VII.

When comparing the two tonicizing ii7–V7–Imaj7s from mm. 10–12 and 21–23, notice that they occur in different locations and therefore have very different structural roles. Which one is more important? The one from mm. 21–23 because it closes the B section of the song with yet another tonicization of a chromatic key area: the flat submediant, ♭VI. The (ii7–V7)/V in mm. 10–12, meanwhile, is located within a phrase and barely passes through the dominant key area. Even though it tonicizes a secondary tonal area, that tonicization is not confirmed as the phrase continues and closes in a different key, namely G major. This type of tonicization has a prolongational aspect to it. Finally, in m. 30, there is another type of a ii7–V7 progression, yet without the resolution. This progression is notated in square brackets (representing a harmonic ellipsis) with a Roman numeral indicating its “non-existing” resolution to ♭III. This is referred to as an incomplete ii7–V7 progression. Figure 11.4 illustrates the location of different ii7–V7s occurring in the tune.

Keyboard Textures





CHAPTER SUMMARY



* * *



Chapter 12 introduces seven models of realizing harmonic progressions on the keyboard.





CONCEPTS AND TERMS

• Model I

MODELS OF KEYBOARD-STYLE PLAYING




* * *



The ability to realize harmonic progressions on the keyboard is an essential skill for the contemporary jazz musician, regardless of her/his primary instrument. The forthcoming models of keyboard playing will help to accomplish this objective.





Model I


• Guide-tone lines in the right hand (RH.).

• Roots of chords in the left hand (L.H.) in 1:1 ratio with the R.H.

Figure 12.1 demonstrates Model I using the major and minor versions of the II–V–I progression. Notice that the R.H. explores the invertible potential of the guide tones.



FIGURE 12.1 Keyboard Realization: Model I





Model II

• Rhythmicized guide tones in the R.H.

• Roots, thirds or fifths in the L.H. in 2:1 ratio with the RH.

Figure 12.2 illustrates the use of Model II. The RH. distributes the Charleston rhythm at different locations within the measure.





Model III

• Root position and inversions of four-part chords in the R.H. (NO voice-leading considerations.)

• Roots of chords in the L.H. in 1:1 ratio with the R.H.

The focus of Model III, shown in Figure 12.3, is to explore only one position or inversion of the four-part chord throughout the progression.





Model IV

• Root position and inversions in the R.H. realized with good voice leading.

• Roots, 3rds, or 5ths in the L.H. in 2:1 ratio with the RH.





FIGURE 12.2 Keyboard Realization: Model II



In order to realize harmonic progressions using Model IV, you need to resolve the 3rds and 7ths of corresponding chords properly and remember the rules of good voice leading between chords (i.e. common-tone retention, stepwise motion, and contrary outer-voice counterpoint). Each progression in Figure 12.4 starts on a different inversion of the ii7 chord, which in turn affects the subsequent voice leading of the progression.



FIGURE 12.3 Keyboard Realization: Model III




FIGURE 12.4 Keyboard Realization: Model IV





Model V

• Rootless five-part chords in the R.H. (NO voice-leading considerations.)

• Roots of chords in the L.H. in 1:1 ratio with the R.H.

Broadly speaking, so-called rootless formations omit the root of the chord from their structure. With rootless five-part chords, the upper four-part structure is placed in the RH. and the root in the L.H. Some of the RH. shapes should look, sound, and feel familiar, since they have already been encountered in the four-part chords in the context of Model III and Model IV. Similar to Model III, we will first acquaint ourselves with four rotations of the rootless formation. Figure 12.5 provides four Model V realizations of the major and minor versions of the II–V–I progression, with each realization beginning on a different R.H. shape.





Model VI

• Rootless five-part chords in the R.H. realized with good voice leading.

• Roots, thirds, or fifths in the L.H. in 2:1 ratio with the R.H.

The motion between chords in Model VI shown in Figure 12.6 is controlled by the principles of good voice leading.





Model VII

• Various chords realized in “chorale style” with equal distribution of notes in both hands.

Model VII uses two voices per hand and employs different four-, five- and larger-part harmonic structures. Since this model uses only four-voice textures, larger formations need to be reduced to their essential harmonic frameworks. In reducing chords to their four-part frameworks certain notes are retained and others omitted. Typically, the root is retained, the 5th is omitted, and—depending on the context—the remaining three voices are selected from the related guide tones, pitch alterations, or extensions. Figure 12.7 demonstrates different Model VII realizations of the II–V–I progression. The selection of chords differs from one realization to the next and depends both on the voicing of the opening chord and on the voice-leading forces initiated by the initial two chords.





These seven models of harmonic realization get progressively more advanced, but even the initial ones—provided that they are performed in time and with a good rhythmic feel—can convincingly express the majority of jazz progressions. As you get more comfortable at realizing harmonic progressions using these models, experiment with different metric placements and variations of the Charleston rhythm.

CHAPTER THIRTEEN


Idiomatic Jazz Progressions





CHAPTER SUMMARY



* * *



Chapter 13 investigates two- and four-bar idiomatic jazz progressions. It also focuses on aural identification and keyboard realization of non-modulatory and modulatory progressions with various ii7–V7 or interpolations, as well as miscellaneous four-bar phrases.





CONCEPTS AND TERMS




* * *



• “Coltrane” substitutions

• Dominant saturation

• Harmonic progressions:

“Countdown”



“Giant Steps”



“Lady Bird”



• Major-third cycles

• Modulations

• Symmetrical intervallic cycles

• Tag endings

• Tritone invariance

• Tritone substitutions

• Turnarounds

• Turnbacks

• ii7–V7 diminutions





TRITONE SUBSTITUTIONS




* * *



The ii7–V7–Imaj7 progression constitutes the perfect vehicle to introduce one of the most important features of jazz harmony: the tritone substitution, notated as TR/X7. The tritone substitution has its theoretical origins in the equal or symmetrical division of the octave. This substitution is associated with the dominant 7th chord and capitalizes on inversional invariance of the tritone inherent to the dominant 7th formation. The interval of a tritone between the 3rd and the 7th is invariant (i.e. remains unchanged) when the root of a dominant 7th is replaced by the root of another dominant 7th chord a tritone away. By virtue of sharing the same tritone, which includes the most essential notes from the chord, the two dominant 7th chords also share the same functional status. The symbol “TR/X7” indicates a tritone substitute formation in relation to some dominant 7th chord. For instance, a TR/V7 in the key of C major stands for the D♭7 chord, because D♭7 is the tritone substitution of G7; a TR/VI7 in the same key indicates E♭7 as the tritone substitution of A7. In both cases the chordal roots of the diatonic and chromatic 7th chords are a tritone apart. Figure 13.1 explains inversional invariance of the tritone using a ii7–V7–Imaj7 progression in C major.



FIGURE 13.1 Tritone Substitution



The tritone F4–B4 is invariant when the root of D♭7 replaces the root of G7. With that root replacement, the 3rd and the 7th swap their chord-tone status: the 3rd of V7 becomes the enharmonic 7th of TR/V7, and the 7th of V7 becomes the 3rd of TR/V7. As functionally equivalent dominant 7ths, V7 and TR/V7are ideal substitutes for one another. If any dominant 7th chord is replaced with its tritone substitution then the chord tones, extensions, and alterations change their harmonic status. Figure 13.2 illustrates that relationship.



FIGURE 13.2 The Status of Chords Tones, Alterations, and Extensions





The ii7–V7–Imaj7 Progression and Tritone Substitutions


Given the premise that the ii7–V7–Imaj7 progression expands the fundamental V–I motion, the rate of harmonic rhythm is increased by adding a local ii7 in front of any secondary dominant 7th. That expansion allows for creative ways to manipulate harmonic rhythm and enhance the structure of harmonic progressions. Figure 13.3 illustrates some of the more interesting transformations of the ii7–V7–Imaj7 progression using the tritone substitutions and ii7–V7 expansions. Chords in bold indicate tritone substitutions.



FIGURE 13.3 Tritone Substitutions and ii7–V7 Expansions





TURNAROUNDS




* * *



In addition to the ii7–V7–Imaj7 and progressions, there are other harmonic progressions that often occur in standard tunes. Probably the most recognizable progression is a turnaround, also known as a turnback. The turnaround is a two- or four-bar progression, usually with a faster harmonic rhythm, that typically occurs at the end of 8- or 16-bar phrases. One of the formal functions of the turnaround is to effectively prepare the arrival of the “top of the chorus” by ushering in a familiar chord progression.1 Just as the ii7–V7–Imaj7 progression can be transformed with different harmonic substitutions, so too can turnarounds.





The Imaj7–vi7–ii7–V7 Progression


Figure 13.4 shows a diatonic Imaj7–vi7–ii7–V7 progression realized using Model I of keyboard style playing.



FIGURE 13.4 The Imaj7–vi7–ii7–V7 Turnaround





This progression extends the diatonic ii7–V7–Imaj7 by another fifth-related chord built on . The submediant chord in the major key has a dual harmonic function: tonic and predominant. In the context of this progression, the vi7 chord functions as a tonic prolongation or tonic expansion. To prolong a chord means to use an auxiliary chord (or chords) that share the same harmonic function with the chord being prolonged.





Harmonic Transformations


Jazz musicians often use different harmonic substitutions to modify the content of diatonic progressions. The most common harmonic modifications of the Imaj7–vi7–ii7–V7 progression involve the use of secondary dominant chords (V7/X), and tritone substitutions (TR/X7). Figure 13.5 demonstrates these substitutions using Model III of harmonic realization.

The secondary dominant 7ths A7 and D7 are analyzed with two different Roman numeral labels VI7 and V7/ii, and II7 and V7/V, which can be used interchangeably. The tritone substitutions, E♭7 and D♭7, also use two Roman numerals, ♭III7 and TR/VI7, and ♭II7 and TR/V7, respectively.



FIGURE 13.5 Tritone Substitutions in the Imaj7–vi7–ii7–V7 Progression





TAG ENDINGS




* * *



Tag endings are somewhat related to turnarounds in their basic harmonic structure, but play different roles in tunes and complete performances. A tag ending occurs at the very end of a tune, repeats a chord sequence (which in the course of subsequent repetitions becomes harmonically transformed), and has an indeterminate duration. Only the final repetition of the tag ending progression is harmonically closed with a clear confirmation of the tonic. Its basic role in the performance is to provide a satisfactory, coda-like ending with a final improvisational flair. As Miles Davis demonstrated on his many recordings, tag endings may take on a life of their own—especially with Herbie Hancock, Ron Carter, and Tony Williams in the rhythm section—and frequently exceeded the length of his solos.2

Tag endings and turnarounds often share similar chord progressions: the only difference between the Imaj7–vi7–ii7–V7 and the iii7–vi7–ii7–V7 is that the former begins on the tonic and the latter on the mediant chord. These two chords, Imaj7 and iii7, are said to be functionally equivalent and are frequently used to substitute for one another. Figure 13.6 illustrates a iii7–vi7–ii7–V7 tag ending progression realized with Model II of keyboard playing. Each measure displaces the Charleston rhythm by a half beat.

Each of these chords can be further substituted by a secondary dominant 7th and, subsequently, by a TR/X7. Since a tag ending progression is usually four bars long, we can demonstrate the use of two harmonic techniques that will double the rate of harmonic rhythm in each measure. The technique of dominant saturation combines two dominant 7th chords, diatonic or chromatic and its TR/X7 (or vice versa) next to each other. The use of ii7–V7 diminution technique expands any dominant 7th chord into a local ii7–V7 progression. Figure 13.7 demonstrates these techniques in the context of a iii7–vi7–ii7–V7 progression realized in Model II of keyboard playing. The second note of the Charleston rhythm anticipates the forthcoming chord by a half beat; this enhances the forward motion of the progression.



FIGURE 13.6 Tag Endings




FIGURE 13.7 Harmonic Expansions





THE CYCLE OF DOMINANT 7THS PROGRESSION




* * *



Probably the most famous occurrence of the cycle of dominant 7ths progression is in the bridge of “I Got Rhythm,” by George and Ira Gershwin. In the discussion of secondary dominants the term “the dominant of the dominant” was used to indicate the relationship between the secondary dominant V7/V and the structural dominant 7th V7. Since the cycle of dominant 7ths progression uses three secondary dominants prior to the structural dominant 7th, that progression can be called by a very long and impractical name: the dominant of the dominant of the dominant of the dominant 7th. Or a more practical way to name it is to use Roman numerals: V7/vi–V7/ii–V7/V–V7 or III7–VI7–II7–V7.



Figure 13.8 illustrates two cycles of dominant 7ths progression in the key of C major: “diatonic” realized in Model IV of keyboard playing, and chromatic with tritone substitutions in m. 2 and m. 4 using Model VI. These progressions explore different rotations of the opening chord.





THE “LADY BIRD” PROGRESSION




* * *



The terms “turnaround” and “tag ending” are generic labels that do not indicate a particular chord sequence; rather, they suggest the specific formal function of these progressions. In jazz, there is a certain subset of harmonic progressions whose names suggest specific chord successions. When jazz musicians use the term “Lady Bird” progression, for instance, it connotes a particular chromatic turnaround from Tadd Dameron’s tune of the same title recorded in 1947. Figure 13.9 illustrates the chord structure of that progression using Model VI of harmonic realization.



FIGURE 13.8 The Cycle of Dominant 7ths Progression




FIGURE 13.9 The “Lady Bird” Progression





As indicated with Roman numerals, the E♭7 chord can be explained as a tritone substitution of A7 or as a tonicization of the ♭VI key area. The ♭VI key area establishes a major third relation with the underlying tonic. Dameron’s iconic progression foreshadows even more daring harmonic experiments with the complete major-third cycles that came to fruition in John Coltrane’s composition “Giant Steps.”





“COLTRANE” SUBSTITUTIONS

John Coltrane’s recording of Giant Steps in 1959 epitomized his three-year period of harmonic explorations, most notably with symmetrical intervallic cycles.3 His composition “Countdown,” which is based on Miles Davis’s “Tune Up,” illustrates the use of so-called “Coltrane” substitutions. Characterized by fast harmonic rhythm, this substitution projects a major-third cycle in which each local major 7th chord is tonicized with the corresponding dominant 7th. In the context of the Dmin7–G7–CMaj7 progression shown in Figure 13.10, the first member of the major-third cycle, ♭VImaj7, is accessed through its dominant 7th that follows the structural predominant, ii7. The next member of the major-third cycle, IIImaj7, is also preceded by its dominant, V7/III, before the progression completes its trajectory with the structural dominant 7th resolving to the tonic.



FIGURE 13.10 The “Countdown” Progression





The “Giant Steps” progression is closely related to the “Countdown” progression with one exception: it forms a complete major-third cycle, thus dividing the octave into equidistant major 3rds. Figure 13.11 illustrates the harmonic structure of the “Giant Steps” progression in the key of C major using Model VI of harmonic realization.

AURAL IDENTIFICATION OF FOUR-BAR PROGRESSIONS

The [ii7–V7]/X Interpolation


The focus now shifts to identifying and realizing four-bar phrases with diatonic or chromatic [ii7–V7]/X interpolations. A [ii7–V7]/X indicates an incomplete ii7–V7 of one of 11 possible local tonics to which the progression could potentially have resolved. This type of chord interpolation represents a harmonic ellipsis. In the generic prototype shown in Figure 13.12, a [ii7–V7]/X is inserted between two structural ii7–V7s.



FIGURE 13.12 Prototypical [ii7–V7]/X Interpolation


In learning to identify these progressions aurally, two approaches are employed: (1) a focus on the intervallic distance between individual chords, and (2) a focus on the intervallic distance between diatonic and interpolated ii7–V7s. Figure 13.13 lists all possible [ii7–V7]/X interpolations and specifies the intervallic relationship between the structural ii7–V7 and a [ii7–V7]/X interpolation: the first interval indicates the distance between V7 and [ii7] and the second interval between the ii7 and a [ii7]. The phrases in Figure 13.13 are organized from the easiest to the most challenging to identify.



FIGURE 13.13 [ii7–V7]/X Interpolations—Intervallic Relationships


Figure 13.14 realizes these progressions using Models I, III, and VI of keyboard playing. Play these (and the forthcoming) progressions at your own comfortable speed with a metronome (set on “2 and 4” to ) then gradually increase the tempo. Invert the opening sonority in order to familiarize yourself with less familiar chordal shapes.





Four-Bar Modulations


Figure 13.15 illustrates a rhythmic distribution of chords within a modulatory four-bar phrase. An “X” indicates the new tonic.



FIGURE 13.14 Model Realizations


The permanent shift to a new tonal area is referred to as a modulation. There are specific conditions for a modulation to take place. To begin with, a clearly established tonic is necessary from which to modulate. Next, the original tonic must be destabilized and proceed toward a predominant key area. A motion away from the tonic, however, is not considered a modulation and neither is a chromatic [ii7–V7]/X interpolation. In order for a modulation to have occurred, the new key must be prolonged and confirmed by a cadence. In jazz harmony, that cadential confirmation typically uses some sort of a ii7–V7–Imaj7 progression. The four-bar generic model from Figure 13.15 summarizes these events. For instance, mm. 1–2 illustrate the initial tonic and its subsequent prolongation and confirmation; mm. 3–4 summarize possible activities in a new key area and its confirmation.





FIGURE 13.15 Four-Bar Modulations


Figure 13.16 compiles 11 four-bar modulatory phrases divided into two broad categories: closely related keys and remotely related keys. They are organized hierarchically according to their degree of remoteness from the initial tonic. The ability to hear modulations will help to identify these types of tonal shift in standard tunes, particularly between individual sections of the tune.

Figure 13.17 realizes these progressions using Models I, III, and IV of keyboard playing.

Having discussed different combinations of the ii7–V7–Imaj7 and progressions, we can now explore four-bar progressions that might be encountered in standard tunes. Figure 13.24a–d illustrates four-bar phrases that begin on I, ii, IV, and vi.

Figure 13.24a compiles 13 four-bar phrases that begin on the tonic chord: some of these phrases are harmonically open and end with the structural ii7–V7 progression; others feature substitute dominants, such as TR/V7 or ♭VII7; still others end with a tonicization of two closely related keys—IV and vi.4 Figure 13.24b illustrates seven four-bar phrases that start with the ii7–V7 or progressions.5 Figure 13.24c shows six four-bar phrases that begin on the subdominant chord.6 The IVmaj7 opening makes them challenging to identify and easily confused with phrases that start on Imaj7. Figure 13.24d demonstrates five four-bar phrases that begin on the submediant chord.7

CHAPTER FOURTEEN


Voicings





CHAPTER SUMMARY



* * *



Chapter 14 discusses three types of voicing chord, upper-structure triads, rootless formations and incomplete voicings, and explores their harmonic and voice-leading potential.





CONCEPTS AND TERMS




* * *



•Dominant aggregates

•Incomplete voicings

•Polychords

•Rootless formations

•Upper-structure triads:

Major



Minor





UPPER-STRUCTURE TRIADS




* * *



The use of upper-structure triads involves the superimposition of major or minor triads on top of single notes, guide tones, triads, and intervallic structures. Upper-structure triads add a new set of practical and theoretical issues. With this powerful tool, the number of ways to generate a collection of notes and harness it for compositional, improvisational, and orchestrational purposes is greatly increased. To notate these large harmonic formations, the so-called slash notation is implemented, which makes complex chords relatively easy to interpret. Two types of slash are employed: a diagonal slash that indicates an upper-structure triad written on the left side of the slash and superimposed on top of a single bass note; and a horizontal slash that indicates an upper-structure triad written on top, superimposed over a chord notated below the slash. The horizontal slash, then, denotes polychordal structures that can accommodate as many as eight distinct notes. The term “polychord” indicates two chords that sound simultaneously.

Although upper structures occur in different types of chord, they will be demonstrated in the context of the dominant 7th chord. The dominant 7th allows the largest and the most diverse assortment of extensions and pitch alterations within its structure. These extensions and alterations can be combined and distributed using various major and minor upper-structure triads. Broadly speaking, there are five major and five minor upper structures that can be added to the dominant 7th chord. The reason for this stems from the specific pitch combinations that these upper triads create and the voice-leading behaviors that the participating extensions and alterations project.

There are five major upper-structure triads, built on 2, ♭3, ♭5 (♯4), ♭6, and 6, that can expand the dominant 7th chord with properly distributed extensions and alterations. The relationship between the root of the dominant 7th chord and the root of the upper structure is illustrated using Arabic numbers. Major upper structures are notated with upper-case Roman numerals: II on 2, ♭III on ♭3, ♭V on ♭5 (♯IV on ♯4), ♭VI on ♭6, and VI on 6. For instance, a B♭ major triad in the context of G7 is notated as ♭III, yet the same triad in the context of E7 is notated as ♭V or ♯IV.

In addition to five major upper structures, there are five minor upper-structure triads that can also expand the structure of the dominant 7th chord. Minor triads are built on 174♭2, ♭3, ♭5 (♯4), 5, and 6, and produce different distributions of chordal extensions and alterations. Minor upper structures are notated using lower-case Roman numerals: ♭ii on ♭2, ♭iii on ♭3, ♭v on ♭5 (♯iv on ♯4), v on 5, and vi on 6. For instance, an E minor triad in the context on E♭7 is notated as ♭ii, and that same triad in the context on G7 is notated as vi. Figure 14.1 illustrates the distribution of major and minor upper-structure triads in the context of C7.



FIGURE 14.1 Upper-Structure Triads in the Dominant 7th Chord


In order to implement these chords in practice, one must be able to identify them aurally. The first step in that process is to concentrate on the quality of the upper-structure triad. When the quality of the triad is identified, the recognition of the specific six-part formation depends on the ability to perceive the sound of individual extensions and pitch alterations. Extensions and alterations are characterized by a unique sound and project specific voice-leading behaviors. The ability to identify those behaviors depends, in large part, on imagining the harmonic context in which a particular chord might appear. Figure 14.2 provides that context. In studying these progressions, pay close attention to the linear behavior of the extensions and pitch alterations.





Dominant Aggregate


Upper-structure formations are extremely useful in reharmonization. In order to internalize their pitch structure, they can be used to harmonize a chromatic scale without 4 and ♯7. The ten-note scale represents all available notes that can feasibly participate in the dominant 7th chord. That collection of notes is known as the dominant aggregate. Simply put, in harmonizing the ten-note scale with upper-structure triads, we will explore the inversional potential of major and minor triads, exhaust all available triadic possibilities, and discover that certain pitches can support more than a single triad. Figure 14.3 demonstrates the harmonization of a dominant aggregate with the available upper-structure triads with the scale unfolding in the top, middle, and bottom voice of the triad, respectively.





ROOTLESS FORMATIONS




* * *



Five-part chords are often used in an abbreviated form as so-called rootless formations. As the name suggests, these types of chord leave out the root and employ the remaining notes to project the character of a chord. Without the root, a chord loses the fundamental pitch that enforces its quality, position, and function. Rootless chords tend to be harmonically and aurally more ambiguous than complete chords. Jazz musicians can capitalize on that ambiguity.

The concept of rootless formations brings up an important point about the role of the bass voice. In most performance situations the root is provided by the bass player. In chord progressions that feature rootless formations (i.e. comping) one can no longer rely on the lowest voice to articulate the changes of a tune, but should rely instead on principles of voice leading and counterpoint to supply clear indications of harmonic motion. Rootless formations are just as effective in expressing the meaning of chords and harmonic progressions as complete chords. Understandably, they are far more challenging to implement. In spite of these challenges—or because of them—they are harmonically more flexible and effective in covering all kinds of harmonic relationship.



FIGURE 14.2 Resolutions of Upper-Structure Triads




FIGURE 14.3 Dominant Aggregate and Upper-Structure Triads


Rootless formations can borrow chordal roots from other chords, which can redefine the harmonic/functional status of the given chord. What will soon be discovered is that most rootless chords look and sound quite familiar. In a certain sense, however, these familiar traits must be disregarded and a different root superimposed on the bottom of the chord must be imagined. Figure 14.4 provides three- and four-note rootless voicings for five-part chords along with their basic harmonic interpretations. Three-note rootless voicings further reduce the pitch content to its essential components. Some of these voicings cannot be analyzed with traditional chord symbols and get their harmonic meaning from a superimposed bass note or notes.



FIGURE 14.4 Rootless Formations





INCOMPLETE VOICINGS




* * *



An incomplete voicing reduces the number of pitches to those that only convey the quality of a complete chord. The tonal definition of an incomplete voicing might not always be apparent. Its tonal and harmonic clarity depends on two factors: on which note or notes are going to be removed from a complete chord, and on how the intervallic content of a chord is diversified. In spite of their potentially ambiguous sound, however, incomplete voicings can be very effective as voice-leading formations, chordal substitutes, and intervallic structures. The different positions of five-part chords from Chapter 5 will be used to explore these types of formation.

To generate an incomplete voicing, follow these steps:

1.Remove a single pitch from a complete root-position five-part chord.

2.Transfer the ninth of a chord down an octave.

3.Rearrange the notes to create an open four-part voicing.

With these three steps, a large number of voicings (far too many to cover them all) are generated. Figure 14.5 demonstrates the three-step process of generating incomplete voicings.

These incomplete voicings remove a 3rd, a 5th or a 7th from a complete five-part chord. The choice of these notes is not entirely accidental. Granted, by not having a 3rd in the chord there is the potential risk of the lack of harmonic quality, and by not having a 7th, the functionality of a chord may be jeopardized. These incomplete voicings acquire their proper harmonic definition from a specific context in which they occur; in other words, any ambiguous sonority can be contextualized using correct voice leading and dissonance treatment. There is also an inherent logic to the removal of a 3rd and/or a 7th from a voicing. Note that the voicings lacking these pitches have a greater saturation of chromatic extensions. We can further experiment with incomplete voicing formations by removing the chordal root from a root-position five-part chord. Figure 14.6 demonstrates such a voicing for along with three harmonic progressions where that formation can be utilized.



FIGURE 14.5 Incomplete Voicing Formations


The pitch structure of this incomplete voicing hardly suggests a suspended dominant 7th chord. The notes F3, D♯4, A♭4, and B♭4 seem to be more closely related to Fmin11 or a rootless B♭7sus than to . While all these harmonic readings are acceptable, in practice they need to be properly contextualized and correctly realized. In the progressions from Figure 14.6, the incomplete voicing exhibits different functional and contrapuntal behaviors. In Figure 14.6a, for instance, the Fmin11 chord functions as the final tonic; in Figure 14.6b, a rootless B♭7sus functions as a suspended dominant resolving directly to the E♭Maj7 chord; and, in Figure 14.6c, functions as a suspended dominant resolving to C7 and, subsequently, to Fmin11. The same voicing can function as the tonic, dominant, or predominant, in different keys. That challenge was accomplished through careful voice-leading considerations and a proper placement of the incomplete formation within the progressions. In harmonic progressions from Figure 14.6, the rootless sounds convincing and demonstrates that these types of chord are well suited for all kinds of harmonic and functional manipulation. Their inherent ambiguity is, in fact, their biggest asset and can be effectively explored. With such a huge potential for harmonic reinterpretation, incomplete voicings constitute great resources for advancing our own harmonic experiments and expanding our harmonic vocabulary.

BEBOP SCALES




* * *



The so-called Bebop revolution in the late 1930s was probably one of the most important musical events in the history of jazz. Bebop brought about the dawn of modern jazz and with it jazz pedagogy. Bebop language is considerably different from traditional types of jazz, such as Early Jazz, Ragtime, New Orleans styles, Kansas City style, Chicago style, and Swing, not only in its approach to improvisation, but also in its treatment of form, harmony, melody, and rhythm. Broadly speaking, solos became longer, musical forms more codified, harmonies more chromatic, melodies more angular, and rhythmic patterns more intricate. This chapter will discuss the pitch structure of four bebop scales: major, minor, dominant, and intermediary.1 Each of these is further examined in terms of their possible functional associations. These functional associations enable us to choose a correct bebop scale for a specific chord and/or harmonic progression. The functional behavior of bebop scales is similar to the behavior of modes. One of the fundamental differences, however, concerns the number of pitches within these collections. Unlike seven-note modes, bebop scales are comprised of eight distinct pitches. The addition of an extra note to a seven-note scale has vast melodic and harmonic consequences, especially in the chromatic realm.





Major Bebop Scale


Possible Harmonic Function—Tonic and Predominant

Figure 15.1 shows the pitch content of the major bebop scale.

The use of a chromatic passing note between 5 and 6 transforms the Ionian mode into the major bebop scale.2 This chromatic addition allocates all the chord tones on strong beats and passing notes on weak beats in relation to the underlying 4/4 meter. The metric distribution of pitches shown in Figure 15.1 conveys the harmonic and functional forces that are inherent to the structure of the scale. In the major bebop scale, beats 1, 2, 3, and 4 delineate the 6th chord and the offbeats spell out the diminished 7th chord. Figure 15.2 illustrates this scenario. Since bebop scales are associated with different tonal behaviors, harmonic functions, and locations in relation to the underlying key, Arabic numbers (without carets, written in bold) are used to represent their pitch content.



FIGURE 15.1 Major Bebop Scale




FIGURE 15.2 Major 6th and Diminished 7th Chords


What is the significance of this particular distribution of pitches within the major bebop scale? Figure 15.2 demonstrates that the major bebop scale combines two different tonal forces: the tonic represented by the 6th chord and the dominant represented by the diminished 7th chord. The diminished 7th chord is frequently employed as an incomplete dom7(♭9) as it contains a major 3rd, 5th, ♭7th, and ♭9th of the dom7(♭9) whose root is a major 3rd down from the root of the corresponding diminished 7th chord. The diminished 7th chord built on 7 from Figure 15.2 represents the rootless G7(♭9).

Figure 15.3 illustrates the distribution of C6 and its inversions on the chord tones of C major bebop and D°7 with its inversions on the passing notes of the scale.



FIGURE 15.3 Distribution of Major 6th and Diminished 7th Chords


The use of a single chromatic pitch like the one the bebop scale offers allows us to fully explore the metric, melodic, and harmonic potential of that note. It also enables us to control the behavior of two opposing tonal forces, tonic and dominant, and transfer their influence to the content of melodic lines. This type of control refers to the placement of chord tones and passing notes within the measure. When chord tones are displaced from downbeats to offbeats, for instance, their metric position is de-emphasized at the expense of passing notes, which will now receive metric stress. With this subtle metric shift, the content of the lines might become more unstable, without needing to add extra chromatic notes.





Minor Bebop Scales


Possible Harmonic Function—Tonic and Predominant

There are three unique minor bebop scales with a similar pitch structure to the major bebop scale. Minor bebop scales employ a passing note between 5 and ♯6, and ♭7 and 8. The upper tetrachords of these scales are derived from the Melodic Minor and Dorian modes respectively. The former includes ♯7, which enables the projection of a diminished 7th chord, and the latter contains ♭7, which injects a subtle modal flavor to the sound of this scale. The pitch structure of these collections is shown in Figure 15.4.

As far as the distribution of chord tones and passing notes is concerned, in minor ♯7 bebop, the strong beats form a minor 6th chord and the offbeats create a diminished 7th chord. In minor ♭7 bebop, the strong beats also produce a minor 6th chord, but the offbeats generate a dominant 7th chord built on ♯7. In Dorian bebop, the strong beats create a minor 7th chord and the offbeats project a minor 6th chord. Figure 15.5 illustrates the distribution of chords on each scale degree of minor ♯7 bebop, minor ♭7 bebop, and Dorian bebop.



FIGURE 15.4 Minor Bebop Scales




FIGURE 15.5 Distribution of Chords





Dominant Bebop Scale


Possible Harmonic Function—Dominant

The dominant bebop scale is derived from the Mixolydian mode and uses a chromatic passing note between ♯7 and 8(1).3 The spelling of ♯7 indicates that ♭7 from the dominant bebop scale is raised. Figure 15.6 illustrates the structure of the scale.



FIGURE 15.6 Dominant Bebop Scale


The addition of the chromatic note enables the formation of a half-diminished 7th chord on ♯7. The presence of a passing half-diminished 7th further intensifies the dominant character of the scale and implies that ♯7 can be used in the context of dominant 7th chords in more advanced melodic and harmonic settings. Figure 15.7 demonstrates the distribution of chords on each scale degree of the dominant bebop scale.



FIGURE 15.7 Distribution of Chords





The Intermediary/Dominant Bebop Complex


Possible Harmonic Function—Predominant and Dominant

There are two ways of rationalizing the pitch organization of the intermediary bebop scale. Its structure can be examined as an independent collection derived from Dorian mode with a chromatic passing note between ♭3 and 4, or as the dominant bebop scale starting on 5. In both cases, the scale establishes a chord-scale relationship with the minor 7th chord built on the supertonic scale degree. Both methods yield the same pitches and reveal important facts about the pitch structure and chord-scale relationships embedded in this scale. The former method of scale derivation suggests that intermediary bebop is an independent collection that establishes a relationship with the predominant minor 7th chord. The latter method explains ways in which the scale is also connected to dominant bebop.

Because intermediary bebop scale has the same pitch content as dominant bebop, the scale mediates between two tonal functions: predominant and dominant. This succession of tonal functions most often occurs in the context of ii7–V7; this makes the progression an ideal vehicle for the implementation of the intermediary/dominant bebop complex. The only difference between intermediary and dominant bebop scales is the different metric distribution of chord tones and passing notes in relation to the corresponding harmonies. Figure 15.8 illustrates this scenario.

When the pitch structure of G dominant bebop is compared with D intermediary bebop, their content is exactly the same. The root and the 3rd of Dmin7 occur on beats 1 and 2. The chromatic passing note F♯4 falls on the offbeat because of its melodic and harmonic instability. This metric placement impacts the distribution of notes on beats 3 and 4. It seems that the placement of a 4th and a 6th on beats 3 and 4 stymies the logical distribution of chord tones over Dmin7. When we consider, however, that these notes—reinterpreted as the root and the 3rd of G7—foreshadow the dominant 7th harmony by two beats, we can conclude that the use of the intermediary/dominant 7th bebop complex has the potential for manipulating harmonic rhythm and approaching improvisation from a linear, as well as a harmonic perspective.



FIGURE 15.8 Derivation of Intermediary Bebop Scale





PRACTICING BEBOP IMPROVISATION




* * *



We will now begin to practice bebop improvisation using several different routines organized into the following categories: (1) the metric placement of pitches, (2) the addition of extra chromatic notes, (3) the alterations of dominant bebop scales, (4) the exploration of the diminished 7th chord, and (5) the use of triplets.





Metric Placement—Scalar and Arpeggiation Patterns


Figures 15.9a–15.9d illustrate basic routines for internalizing the structure of major and minor bebop scales and for practicing the correct metric placement of pitches from these scales. Since each routine shown below demonstrates a specific scalar or arpeggiation pattern in the context of a single scale, in your practice try exploring different scales with each routine.

Routine 1: Start the scale on a chord tone (downbeat) as shown in Figure 15.9a. Play the scale up and down for two octaves.



FIGURE 15.9A Routine 1: Scalar Patterns





Routine 2: Start the scale on a passing tone (upbeat) of the scale as shown in Figure 15.9b. Play the scale up and down for two octaves.



FIGURE 15.9B Routine 2: Scalar Patterns





Routine 3: Arpeggiate chords built on each scale degree of the bebop scale using the different patterns shown in Figure 15.9c.



FIGURE 15.9C Routine 3: Arpeggiation Patterns





Routine 4: Combine scalar segments with arpeggiation patterns as shown in Figure 15.9d.



FIGURE 15.9D Routine 4: Scalar and Arpeggiation Patterns





Practice these (and all the remaining) routines with a metronome on two and four starting at a medium-slow tempo. Set the metronome to ♩=62 and make each click count as a half note. Gradually increase the tempo to medium-up at ♩=96.

Addition of Extra Chromatic Notes





The addition of extra chromatic notes can further intensify the content of bebop lines. Just as the metric placement of single chromatic passing notes (5–6 in major, 5–♯6 in minor, ♭7–8 in dominant, and ♭3–4 in intermediary) is strictly controlled, so is the addition of extra chromatic notes. Figures 15.10a and 15.10b illustrate two routines for practicing the addition of extra chromatic notes. These two routines can be fully realized in the context of major and dominant bebop scales. The minor and intermediary bebop scales can only accommodate one extra chromatic passing note between 2 and 1. The minor 3rd in their pitch structure prevents us from implementing two chromatic passing notes.

Routine 1: Start the bebop scale on the downbeat of 2 (ascending/descending) and 1 (descending). Add a single upper/lower chromatic passing note (depending on the direction of the line) (Figure 15.10a).



FIGURE 15.10A Routine 1: Addition of Extra Chromatic Note





Routine 2: Start on the downbeat of 3, 5, and 6 of major and dominant bebop, then add two chromatic passing notes between 3–2 and 2–1 (Figure 15.10b).



FIGURE 15.10B Routine 2: Addition of Extra Chromatic Notes





Altered Bebop Scales





Since the dominant function is associated with harmonic tension, the pitch structure of the dominant bebop scale can be modified by applying additional chromatic alterations. In theory, dominant bebop can be enhanced with available chromatic extensions. In practice, however, these alterations should reflect the overall musical context, particularly as it relates to the underlying tonality. Figure 15.11 shows four altered dominant bebop scales.

Because of the presence of ♭13th in dominant ♭13, dominant ♭9/♯9/♭l3, and altered bebop scales, these scales work best in the context of dominant 7th chords occurring in minor keys. Notice that in the dominant ♭9/♯9/♯13 scale, 3 is omitted from the structure of the scale and substituted with ♯2, which functions as an accented dissonance. This substitution preserves the metric placement of 5 and ♯7 on the downbeats 3 and 4, respectively. In the altered bebop scale, the chord tone 3 is relegated to the status of the passing note occurring between ♯2 and ♯4. The placement of chromatic extensions on the downbeats further emphasizes the dissonant status of the scale. Figures 15.12a–15.12c suggest routines for practicing these scales.



FIGURE 15.11 Altered Dominant Bebop Scales





Routine 1: Start the scale on a chord tone (downbeat) as shown in Figure 15.12a. Play the scale up and down for two octaves.



FIGURE 15.12A Routine 1: Altered Dominant Scales





Routine 2: Start the scale on a passing tone (upbeat) as shown in Figure 15.12b. Play the scale up and down for two octaves.



FIGURE 15.12B Routine 2: Altered Dominant Scales





Routine 3: Use the specific arpeggiation pattern with each altered scale, as shown in Figure 15.12c



FIGURE 15.12C Routine 3: Altered Dominant Scales





The Diminished 7th Chord





The diminished 7th chord is an essential building block of bebop improvisation. As a rootless dom7(♭9), the diminished 7th chord is very effective at projecting the tonality of chord progressions with dominant 7th formations. As a chromatic passing sonority occurring on the offbeats of selected bebop scales, the diminished 7th chord can be quite effective at adding chromatic tension to melodic lines, at manipulating the harmonic rhythm of underlying chord progressions, and at providing voice-leading connections between stable formations. All of these applications are ultimately related to the metric placement of the diminished 7th chord. Figures 15.13a–15.13f demonstrate six different routines for practicing the diminished 7th chord.

Routine 1: Explore different shapes of the diminished 7th chord by transferring one or more notes up an octave (Figure 15.13a).4



FIGURE 15.13A Routine 1: Upward Arpeggiation of Diminished 7th





Routine 2: Explore different shapes of the diminished 7th chord by transferring one or more notes down an octave (Figure 15.13b).



FIGURE 15.13B Routine 2: Downward Arpeggiation of Diminished 7th





Routine 3: In the context of a V–I progression, resolve the diminished 7th chord using the direct cadential gesture. A direct cadential gesture reflects the content of the phrase and establishes a strong chord-scale relationship with the underlying harmony (Figure 15.13c).



FIGURE 15.13C Routine 3: V–I: Direct Cadential Gestures





Routine 4: In the context of a V–I progression, resolve the diminished 7th chord using direct cadential gesture (Figure 15.13d).



FIGURE 15.13D Routine 4: Direct Cadential Gestures for V–I





Routine 5: In the context of a V–I progression, resolve the diminished 7th chord using the indirect cadential gesture. An indirect cadential gesture can take many different forms, but it mainly pertains to the relationship with the underlying harmony and the overall metric placement of this gesture. This type of melodic cadence is typically displaced by one or more beats before or after a direct cadential gesture would have occurred (Figure 15.13e).

Routine 6: In the context of a V–I progression, resolve the diminished 7th chord using indirect cadential gesture (Figure 15.13f).



FIGURE 15.13F Routine 6: Indirect Cadential Gestures for V–I





Triplets





The use of triplets adds extra energy and forward motion into melodic lines. Triplets work very well in the context of chordal arpeggiation with single or double neighbor figures preparing the triplet as shown in Figures 15.14a–15.14d.

Routine 1: Add the triplet arpeggiation patterns with the lower chromatic/diatonic neighbor into the structure of bebop scales (Figure 15.14a).



FIGURE 15.14A Routine 1: Triplet Arpeggiation with a Lower Neighbor





As a rule of thumb, each scale degree should be approached with a lower neighbor a half step below the target note. Such a melodic approach results in either diatonic or chromatic neighbors.

Routine 2: Add the triplet arpeggiation patterns with the upper diatonic neighbor into the structure of the bebop scales (Figure 15.14b).



FIGURE 15.14B Routine 2: Triplet Arpeggiation with an Upper Neighbor





Diatonic upper neighbors are derived from the corresponding scale and are located a half and/or whole step above the first note of the triplet figure.

Routine 3: Add the triplet arpeggiation patterns with a double neighbor figure into the structure of the bebop scales (Figure 15.14c).



FIGURE 15.14C Routine 3: Triplet Arpeggiation with a Double Neighbor





Routine 4: Add the arpeggiation patterns with an extended double neighbor figure into the structure of the bebop scales (Figure 15.14d).



FIGURE 15.14D Routine 4: Triplet Arpeggiation with an Extended Double Neighbor





The extended double neighbor figure utilizes two lower neighbors, diatonic and chromatic. To prevent excessive chromaticism, a lower diatonic neighbor initiates the pattern and a lower chromatic neighbor occurs prior to its target note, with the exception of half steps that naturally occur in the scale (i.e. 3, 5, and 7 of major bebop; 2, 5, and ♯7 of minor ♯7; 3, 6, and ♭7 of dominant; and 3, 5, and ♭7 of dominant ♭13).

The ii7–V7–Imaj7 Progression





Figure 15.15 establishes a chord-scale relationship for the ii7–V7–Imaj7 progression using selective bebop scales.



FIGURE 15.15 Bebop Scales for ii7–V7–Imaj7





Each scale features a descending sixth span from the root to the third of the underlying chord. The first two chords of the progression use the same scale—hence the intermediary/ bebop complex label—albeit starting on a different note of the corresponding chords.

Negotiating the Minor Seven Flat Five Chord





Before illustrating the chord-scale relationship for a progression using bebop scales, let us discuss how to negotiate the min7(♭5) chord with bebop scales. The chord-scale relationship between the predominant and bebop scales is more intricate than it is for the predominant ii7. Figure 15.16 demonstrates this relationship.

In order to understand this relationship, the min7(♭5) chord should be examined as if it were a four-part upper structure of the corresponding dominant 9th chord. In Figure 15.16, Dmin7(♭5) constitutes the upper structure of B♭9. Bebop scales that fit the content of min7(♭5), then, are derived from the dominant bebop scales that work for a dominant 9th chord, whose root is a major 3rd down from the root of the min7(♭5) chord. The two scales in Figure 15.16—intermediary ♭2 and intermediary ♮2—begin on the root of min7(♭5) and share the pitch content with the dominant and dominant ♭11 bebop scales. In addition to fitting the structure of min7(♭5), these two intermediary bebop scales also capture the essential characteristics of Locrian and Locrian ♮2 modes—both of which are associated with the predominant .



FIGURE 15.16 Chord-Scale Relationship for the Minor 7(♭5) Chord





The Progression




Figure 15.17 illustrates three chord-scale relationships for the progression using different bebop scales.

In comparison to the ii7–V7–Imaj7 progression, the chord-scale relationship for the progression is more elaborate: unlike in the former, where the first two chords are negotiated with the same dominant bebop scale starting on the roots of respective chords, in the latter each chord can potentially establish a relationship with two different scales. Thus the chord connects with intermediary ♭2 and intermediary ♮2, the V7 chord with dominant ♭13, dominant ♭9/♭9/♭13 and altered bebop scales, and the i7 chord with minor ♯7th, minor ♭7th, and Dorian bebop.

NOTES



* * *



1. In the current discussion, the term “bebop scales” is used loosely to depict particular eight-note constructs with one or more chromatic passing notes at different locations in their structure. The one scale that traditionally goes by this name is the dominant bebop scale (with a passing note between ♭7 and 1); there are Jerry Coker's additional three bebop scales and Mark Levine's four bebop scales, all of which present different scalar constructs. A common misconception about bebop scales is that they originated during the Bebop Era, when, in fact, they were quite common in the repertory of ragtimes, marches, and other popular genres of the late nineteenth and early twentieth centuries. For a clear manifestation of the dominant bebop scale (with a passing note between ♭7 and 1) listen to the transition material after the trio of Lew Pollack's ragtime composition “That's a Plenty” (1914). The pitch succession, F5–E♮5–E♭5–D–C–B♭–A–G–F, clearly delineates what we now call the “bebop scale.”

2. The spelling of the chromatic passing note as ♭6 (A♭ in C major bebop) is in keeping with the correct spelling of the diminished 7th chord (B°7) that forms an essential chord-scale relationship with this scale.

3. This is what most texts refer to as the bebop scale.

4. The great piano player Barry Harris is credited with having codified this technique.





CHAPTER SIXTEEN


Octatonic Scales





CHAPTER SUMMARY



* * *



Chapter 16 examines the pitch structure, chord—scale relationships, harmonic and melodic potential of the octatonic scale.





CONCEPTS AND TERMS




* * *



• Cardinality

• Double-diminished 7th chords

• Octatonic scales:

Half-whole (1/2) octatonic I, II, III



Whole-half (2/1) octatonic I, II, III



• Scalar transpositions

• Transposition through the scale





THE 1/2 OCTATONIC SCALE




* * *



In the previous chapter, we saw how bebop scales expand the number of scale members from seven to eight. Theorists often refer to this expansion as a change in the cardinality of the scale. The term “octatonic” denotes a scale whose cardinality is eight, i.e. the scale consists of eight distinct pitches. The octatonic scale covered in this chapter comes in two unique intervallic arrangements, half-whole and whole-half. The names “half-whole” and “whole-half” refer to the intervallic pattern of major and minor 2nds (or vice versa) recurring throughout these scales. Arabic numbers 2 and 1 represent the intervals of major 2nd and minor 2nd respectively. The designation 1/2 stands for the half—whole octatonic and the 2/1 for the whole—half octatonic. These two octatonic collections exhibit very different functional behaviors and establish important chord—scale relationships. The symmetrical nature of both scales allows for some interesting functional overlaps and a multiplicity of harmonic associations.

The 1/2 octatonic scale is primarily associated with the dominant function. It establishes impressive chord—scale relationships with a variety of dominant 7th formations. The 1/2 octatonic scale is a symmetrical collection that repeats the 1/2 intervallic pattern every other note. The scale partitions the octave into two tritones or four minor 3rds. It also includes two overlapping minor 3rd cycles a half step apart. In C 1/2 octatonic, these cycles feature the following pitch segments: C—E♭—F♯—A and D♭—E—G—B♭. The symmetrical properties of the scale have profound harmonic and melodic implications. They mean that any voicing, chord progression, scalar segment, or melodic cell when transposed up or down a minor 3rd will retain the original shape and functional status. A single 1/2 octatonic will therefore establish the chord—scale relationship with as many as four distinct harmonic formations a minor 3rd apart. The 1/2 octatonic scale has three unique transpositions shown in Figure 16.1. These scalar transpositions are referred to as 1/2 octatonic I, 1/2 octatonic II, and 1/2 octatonic III.

Before exploring the harmonic potential of the scale, let us examine the pitch structure of 1/2 octatonic I in terms of chord tones, pitch alterations, and extensions. Figure 16.2 provides a pitch analysis of 1/2 octatonic I built on C4.



FIGURE 16.1 1/2 Octatonic I, II, III




FIGURE 16.2 1/2 Octatonic I—Pitch Analysis


The scale includes all the chord tones of the C7 harmony: the root, major 3rd, perfect 5th, and minor 7th. It also contains three chromatic extensions, ♭9th, ♯9th and ♯11th, one diatonic extension, major 13th, and one pitch alteration, ♭5th. As such, the 1/2 octatonic establishes a chord—scale relationship with C7(♭5) and C13. In addition, the 1/2 octatonic I scale is a perfect match for the C7(♭9) chord that, until now, has not been paired with a scale or mode. Since the pitch content of any 1/2 octatonic is invariant under minor 3rd transposition, the dominant 7th chords a minor 3rd apart establish chord—scale relationships with the same 1/2 octatonic scale. Therefore, any 1/2 octatonic can be used in conjunction with four distinct dominant 7ths. This ratio of chords to scale relationships is a distinctive feature of the octatonic collection and allows for a highly economical use of the scale. Figure 16.3 examines the pitch structure of 1/2 octatonic I in the context of four dominant 7ths a minor 3rd apart.



FIGURE 16.3 1/2 Octatonic I and Four Minor 3rd-Related Dominant 7ths


Each note of the 1/2 octatonic has a unique chordal membership. For instance, the pitch C5 functions as ♯9th in A7, ♯11th/♭5th in F♯7, major 13th in E♭7, or as the root of C7. What does it mean? It means that in the context of these chords, C5 will exhibit very different voice-leading behaviors that are unique to the specific dominant 7th chord. A note's behavior remains exactly the same in both musical dimensions, vertical and horizontal. In examining the behavior of the second note of the 1/2 octatonic I, D♭4, all the possible harmonic scenarios in which all other notes from the 1/2 octatonic can occur are exhausted. Figure 16.4 illustrates the voice-leading behavior of C5 and D♭5 (C♯5) in the context of C7, E♭7, F♯7, and A7 using V7—Imaj7 or V7—i7 progressions.





Harmonic Potential


In exploring the harmonic potential of 1/2 octatonic, let us examine what happens to a chord in transposition through the scale. Transposition through the scale takes the initial formation and moves it linearly to the nearest available formation derived entirely from the pitches of the scale. For instance, a major triad in root position built on 1 becomes a minor triad in 2nd inversion on ♭2; a half-diminished chord on 1 becomes a dim(♯7) chord on ♭2, etc. The two initial chords, shown in Figure 16.5, create a harmonic pattern that repeats every other note. In transposition through the scale, then, the initial sonority can be thought of as comprised of three or four (depending on the chord's cardinality) melodic lines traversing through the scale in a stepwise fashion.



FIGURE 16.4 Voice-Leading Behavior of C5 and D♭5 (C♯5)




FIGURE 16.5 Harmonic Transposition Through the 1/2 Octatonic I Scale





Melodic Potential


Let us now examine what happens to a motivic cell in transposition through the scale. Just as the structures of harmonic formations built on 1 and ♭2 are different from one another, so is the intervallic design of motivic cells occurring on these pitches. If the original motivic cell built on 1 of 1/2 octatonic features a specific intervallic design, in transposition to ♭2, the order of pitches is preserved but the intervals between the notes change. A melodic pattern combines two recurrences of the original motive on 1 and ♭2 that is subsequently repeated every other note. Figure 16.6 illustrates a few motivic cells transposed through the 1/2 octatonic. The circled numbers between adjacent pitches indicate the semitone count.

What we now know about the structure and behavior of the 1/2 octatonic scale is summarized in the following points:

1. The pitches—1, ♭3, ♯4, and 6—can potentially function as either roots, ♯9ths, ♯11ths (♭5ths), or major 13ths of four dominant 7th chords built on 1, ♭3, ♯4, and 6.

2. The pitches—♭2, 3, 5, and ♭7—can potentially function as either major 3rds, perfect 5ths, minor 7ths, or ♭9ths of four dominant 7th chords built on 1, ♭3, ♯4, and 6.

3. Any harmonic formation or melodic pattern built on 1 retains its original form when transposed up or down a minor 3rd.

4. Any harmonic formation or melodic pattern built on ♭2 retains its original form when transposed up or down a minor 3rd.

5. Any harmonic/melodic pattern combines two occurrences of the initial chord/cell built on 1 and ♭2 and repeats every other note.



FIGURE 16.6 Melodic Transposition Through the 1/2 Octatonic I Scale





THE 2/1 OCTATONIC SCALE




* * *



Since the 2/1 octatonic constitutes the inversion of the 1/2 octatonic, the principles regarding symmetry and transpositional invariance are exactly the same for both scales. The fundamental difference between the two relates to their very different functional associations. The 2/1 octatonic functions largely as a predominant and establishes a basic chord—scale relationship with the diminished 7th chord. The scale has three unique transpositions: 2/1 octatonic I, 2/1 octatonic II, and 2/1 octatonic III. Figure 16.7 illustrates the pitch structure of these scales.

To quickly build a 2/1 octatonic on any pitch, think of two adjacent minor tetrachords separated by a minor 2nd, or two minor tetrachords a tritone apart. Figure 16.8 examines the pitch structure of C 2/1 octatonic I in the context of C°7, E♭°7, F♭°7, and A°7.



FIGURE 16.7 2/1 Octatonic I, II, III




FIGURE 16.8 2/1 Octatonic I and Four Minor 3rd-Related Diminished 7ths


Similar to the relationship between the 1/2 octatonic and the dominant 7th chord, the 2/1 octatonic contains only chord tones and extensions of the diminished 7th chord. By arranging all the notes from the 2/1 octatonic as shown in Figure 16.9, the so-called double-diminished 7th chord is created that contains two gapped diminished 7th formations.

Once we realize that 2/1 octatonic II has the same pitch content as 1/2 octatonic I, then it becomes clear that a single octatonic scale can establish a relationship with dominant 7th and diminished 7th chords. Since the diminished 7th chord often functions as a rootless dom7(♭9), it can use the same scale in different harmonic situations.

CHAPTER SEVENTEEN


Bebop Blues





CHAPTER SUMMARY



* * *



Chapter 17 analyzes three blues progressions from the Bebop Era and proposes additional approaches to blues improvisation.





CONCEPTS AND TERMS

• Blues progressions:

“Billie’s Bounce”



“Bird”



“The Dance Of the Infidels”

• Structural lines





THREE HARMONIC VARIANTS




* * *



One of the essential features of bebop harmony is its fast and intricate harmonic rhythm. What is also interesting about bebop harmony is that some of its characteristic chord members can be traced back to the blues. For instance, a ♯11th (♭5th) or ♯9th over the dominant 7th chord represents the notes of the blues scale: ♭5 and ♭3, respectively. Although, the harmonic surface of certain blues tunes from the Bebop Era might not resemble the harmonic paradigm of the basic blues discussed in Chapter 9, the background structure always preserves the essential harmonies of the blues no matter how complex that surface might be.





Variant 1


Figure 17.1 illustrates an F blues with harmonic substitutions typical of the Bebop Era. This blues progression is based on “Billie’s Bounce” by Charlie Parker.



FIGURE 17.1 “Billie’s Bounce”—Chord Changes


There are a few significant differences between “Billie’s Bounce” and the basic blues progression. The presence of ♯ivo7 in m. 2 and a ()/ii progression in m. 8 offers new improvisational possibilities. The diminished 7th passing chord in m. 2 leads to F7/C in m. 3. The structural V7 in mm. 9–10 is prolonged with four chords: Gmin7–Gmin(♯7)–C7sus–C7. As a consequence, the occurrence of V7 is postponed until m. 10. The preparation of ii7 in m. 8 uses a ()/ii progression. The two harmonic events from mm. 2 and 8 are unique to the structure of this particular blues progression.

In addition to the passing status of the diminished 7th chord in m. 2, this important chord can occur in other harmonic situations, albeit with different functional capacities. Since the diminished 7th chord functions as an upper structure of the dom7(♭9), any dominant 7th chord can potentially utilize this sound. Figure 17.2 establishes a chord–scale relationship for “Billie’s Bounce” and indicates places in which the diminished 7th chord can be implemented. The use of a single octatonic scale in m. 2 demonstrates an economical approach to improvisation wherein a single scale establishes a chord–scale relationship with two different harmonic formations.

Figure 17.3 illustrates a realization of “Billie’s Bounce” using Model II of keyboard style playing. The content of the R.H. is rhythmicized with the Charleston rhythm placed at different metric locations. When this rhythmic gesture appears on beat 3 (or later in the measure) then the second part of the figure utilizes the guide tones of the forthcoming harmony.





Variant 2


Figure 17.4 illustrates the harmonic structure of the “Bird” blues in E♭.1

In this progression, the structural chords in mm. 1 and 5 still occur on the tonic and subdominant scale degrees, respectively, yet instead of dominant 7ths they feature major 7th chords. The motion from I to IV in mm. 1–4 is packed with idiomatic harmonic activity. The parallel motion between the guide tones of E♭Maj7 and Dmin7(♭5) activates the cycle of 5ths progression. The second phrase (mm. 5–8) features two chromatic ii7–V7s in mm. 6 and 8. The former, [ii7–V7]/♭III, is a back-door dominant 7th preparation of the major tonic in m. 7. The chromatic [ii7–V7]/♭II in m. 8 anticipates the arrival of the structural ii7–V7 in mm. 9–10 by a half step. The third four-bar phrase of “Bird” blues in mm. 9–12 has a chord structure similar to the basic blues progression. Figure 17.5 provides a realization of the progression using “drop 2” five-part voicings. The turnaround in mm. 11–12 features alternate harmonic changes.



FIGURE 17.2 “Billie’s Bounce”—A Chord–Scale Relationship




FIGURE 17.3 “Billie’s Bounce”—Model II Realization




FIGURE 17.4 “Bird” Blues—Chord Changes





Variant 3


Figure 17.6 gives the chord changes for Bud Powell’s “The Dance Of the Infidels” in C.2

The opening phrase in mm. 1–4 includes two chromatic ii7–V7s. The [ii7–V7]/♭VII progression in m. 2 functions as a tonic expansion and the [ii7–V7]/VII in m. 4 functions as a ii7–V7 tritone expansion of C7. Note that in m. 3, the voice-leading preparation of [ii7–V7]/VII uses two parallel minor 7th chords: iii7 and ii7: these are realized as quartal structures in Figure 17.7. The occurrence of the structural subdominant in m. 5 is delayed until m. 6 by its corresponding predominant. This predominant expansion forms a minor 2nd relationship with the preceding [ii7–V7]/VII. One of the most effective chord substitutions of this blues progression occurs in mm. 9–10. The structural dominant 7th, which should have occurred in m. 10, is replaced by a [ii7–V7]/♯IV progression. The nature of this substitution is analogous to the [ii7–V7]/VII progression from m. 4. In both cases, the ii7–V7 tritone expansions prepare and/or disguise the occurrence of structural harmonies. Figure 17.7 provides a “drop 2” realization of “The Dance Of the Infidels” with alternate changes for the turnaround.

FIGURE 17.7 “The Dance Of the Infidels”—“Drop 2” Five-Part Realization





IMPROVISATION




* * *



We will now discuss two approaches to improvisation using Variants 2 and 3 of the blues. The first approach is based on arpeggiations of rootless five-part chords over the structural line. The second approach is based on finding the most efficient way of connecting closely or distantly related chords. Arpeggiation of rootless formations using the notes of a background line is an effective improvisational strategy demonstrating one’s understanding of chord structures and voice leading. Such a background line uses whole and half notes (depending on the rate of harmonic rhythm) that are derived from the underlying harmony and that primarily move by step. The individual notes function as “roots” of the corresponding rootless five-part formations that are subsequently arpeggiated. Figure 17.8 demonstrates two background lines derived from the “Bird” blues embellished with chord arpeggiations.

The use of common-tone (or stepwise) connections is based on finding a pitch that is called an entry window. This pitch allows for a smooth connection between closely or distantly related chords or key areas. If we know, for instance, that the 7th of ii7 also functions as the 3rd of ♭VI7, then this particular pitch can be used as an entry window to connect these two chords. If we also know that it is possible to connect ii7 and ♭VI7 by moving the 9th of ii7 by a half step (in either direction) to land on the 5th or 13th of ♭VI7, then doing so will guarantee good voice leading. Figure 17.9 illustrates available entry windows in “The Dance Of the Infidels” and the bottom line integrates these pitches in the context of melodic lines.

“CONFIRMATION”—AN ANALYSIS




* * *



Figure 18.1 illustrates the lead sheet of “Confirmation” by Charlie Parker.1





Form and Harmony


“Confirmation” features a 32-bar AABA formal design with slight melodic variations in each A section. The chord progression in the A section employs a chain of local II–Vs preparing the arrival of the structural IV in mm. 5, 13, and 29. This characteristic chord sequence bridging two harmonic pillars, I and IV, is one of the most dominan harmonic expansions associated with the blues and other tunes as well.2 As is the case with most compositions from the Bebop Era, the harmonic rhythm of “Confirmation” is fast and intricate. For instance, mm. 1–4 feature an idiomatic progression with a sequence of dominant 7ths that begins on () in m. 2, descends by whole steps to () in m. 4, and resolves to the subdominant in m. 5. Each dominant 7th in mm. 2–4 is subsequently expanded 7 with the ii()–V or ii7–V7 progressions, thereby doubling the rate of harmonic rhythm. In m. 2, then, A7 becomes Emin7(♭5)–A7; in m. 3, G7 turns into Dmin7–G7; and, in m. 4, F7 expands into Cmin7–F7.



FIGURE 18.1 Lead Sheet—“Confirmation”

Comparing the second half of each A section shows that the first A is harmonically open and ends on a ii7–V7 in m. 8, while the second and the last A feature closed harmonic cadences on I in m. 16 and m. 32, respectively. The bridge in mm. 17–24 has a symmetrical phrase structure and slower harmonic rhythm, which redirects the harmony from I to IV in m. 19 and, then, to ♭VI in m. 23. These key areas are tonicized with local ii7–V7 progressions. The choice of these tonal areas corroborates an interesting fact about the overall tonality of bebop tunes with respect to jazz traditions. The subdominant key area has always had strong blues underpinnings and the flat submediant was one of the few chromatic regions that ragtime or early jazz tunes allowed in their harmonic structure.3





Melody and Rhythm


The melody of “Confirmation” has an interesting structural design. The background line –– in mm. 1–4, for instance, controls the unfolding of the melodic surface. The beginning of each measure highlights the structural tones at prominent metric positions. Scale degree two in m. 2—which in the context of the underlying chords functions as the 3rd and the 7th, respectively—resolves to the 3rd of Dmin7 in m. 3, completing the –– span. In mm. 17–19, the pitch succession –♭–––– (local 8–♯7–♭7–6–5)—although occurring over the ii7–V7–Imaj7 in B—is an idiomatic line that also controls the content of the melodic diminutions. Figure 18.2 illustrates these two spans.

The melody also features some interesting blues inflections. With the arrival of the structural harmony in m. 5, for instance, the melody highlights a pitch succession that utilizes two blue notes: ♭ and ♭. In mm. 9–10, ♭ and ♭ continue to embellish the melody with ♭ in m. 10 implicating a ♭5th of the A7 harmony. In m. 22, the same blue notes, ♭ and ♭, become harmonically redefined in the context of V7/♭VI.



FIGURE 18.2 “Confirmation”—Structural Spans

One of the characteristic sonorities from the Bebop Era is the diminished 7th formation. This chord typically functions as a rootless dom7(♭9). In m. 8, the pitch D♭5, which constitutes the ♭9th of C7, is featured prominently on beat 1; in m. 24, D♭4 occurs in the context of a phrase that anticipates the return of the final A section. In both cases, the resolution of these notes follows the rules of good voice leading.

The rhythm of “Confirmation” is likewise typical of the Bebop Era. The melody features syncopations, upbeats, eight-note anticipations of the forthcoming harmony, and compelling cadential gestures. The rhythmic design of the melody is particularly effective at the end of phrases. In mm. 2–3, for instance, a short two-note gesture occurring at the “and” of 4 and 1 concludes the presentation of the opening phrase. In m. 7, another two-note figure on beat 2, utilizing a major 13th and a major 9th of G7, effectively terminates the preceding phrase. In m. 15, a four-note figure on beats 3 and 4 delineates the underlying harmony and, at the same time, anticipates the forthcoming harmony.





AN ANALYSIS OF THE TRANSCRIPTION




* * *



Hank Jones’s solo on “Confirmation,” shown in Figure 18.3, is from the album Bebop Redux, recorded in 1977. In this solo, Jones shows how two jazz traditions—blues and bebop—can be integrated in a musically convincing manner. He also demonstrates a stunning command of the bebop language manifested in a linear approach to improvisation.

As indicated in the analysis of the tune, the A section of “Confirmation” contains elements of the blues, such as single blue-note inflections and characteristic blues harmonies. Jones capitalizes on the blues potential of the tune in a number of creative ways. At the end of chorus 1 in mm. 29–32, for instance, the entire phrase has a strong blues “flavor” marked by the use of ♭ and ♭. In the subsequent choruses, the use of the blues—especially in the second half of the A section—becomes even more intense. Notice how Jones infuses the music with the blues elements in mm. 45–48, 61–64, 93–96, or 125–128.

Broadly speaking, each phrase of the solo is an example of Jones’s excellent command of bebop vocabulary; not only do his phrases demonstrate total control of the language, but they also illustrate ways in which Jones generates melodic ideas from the tune itself. This much is already clear from mm. 1–8. Each line features a balanced use of steps and skips, clear metric distribution of chord tones and extensions, and controlled use of chromaticism. Note how Jones shapes the melodic line in mm. 4–6. The line begins with an eight-note pick up, which establishes linear continuity with the previous E4, then ascends to G5 in m. 4 with a clear distribution of chord tones on strong beats. The phrase con -tinuation in mm. 5–6 balances the line with a stepwise descent, G5–F5–E5–D5–C5, embellished with surface arpeggiations of the underlying chords.

As previously mentioned, the use of diminished 7th chords in the context of dom7(♭9) is synonymous with bebop syntax and Jones often highlights this chord in his solo. His treatment of the sonority is very creative and includes arpeggiation (mm. 10 and 34), incomplete diminished 7th (mm. 24 and 98), and metric displacement (mm. 26–27 and 40).





FIGURE 18.3 “Confirmation”—Improvised Solo by Hank Jones (transcribed by Dariusz Terefenko)

The solo is unified through the use of similar melodic devices at the same locations within the form. For instance, in mm. 4, 12, and 28 of the form, Jones frequently employs a dom7(♯5) chord (mm. 4, 12, 36, 92, 100, and 108). The melodic ideas seem to foreshadow the arrival of the main tonic rather than to articulate the underlying harmony in mm. 7, 71, and 103. More importantly, the beginning of each chorus emphasizes , which occurs in various guises in the original tune (mm. 1, 17, and 25). At the beginning of each chorus, Jones comes back to and slightly modifies its status from the previous chorus: in m. 1, is prepared with a two-note pick up derived from the tonic bebop scale; in m. 33, initiates a diatonic scalar ascent; in m. 65, introduces a chromatic scalar ascent; and, in m. 97, begins an idiomatic line with varied contour.

Among many features of the solo, Jones’s treatment of chromaticism is masterly. In the discussion of bebop scales in Chapter 15, I emphasized that the addition of a single chromatic note to a seven-note scale creates an ideal metric scenario in which chord tones are distributed on strong beats and non-chord tones on weak beats. Some interesting examples occur in m. 4, where G♭5 functions as an unaccented passing note, m. 20, where C♯5 serves as an accented passing note, m. 42, where D♯5 initiates the phrase, m. 99, where E♭5 ends the phrase, m. 87, where D major is a chromatic upper-structure triad over D♭Maj7, and m. 59, where C♯min7 functions as an chromatic upper-structure four-part chord over G7.

Jones also uses an impressive assortment of cadential melodic gestures in his solo. These patterns usually accomplish two objectives: (1) they provide a logical phrase conclusion and (2) they foreshadow the arrival of the next phrase. In m. 23, for instance, a two-note succession E♭4–A♭3 ends the two-bar phrase. This simple gesture is very effective because it clearly delineates the underlying harmony, provides voice-leading resolution of the chromatic notes E4–A3 from m. 22, anticipates the beginning of the next phrase that starts an octave higher on A♭4, and recurs in the middle of the phrase (m. 24) at a different pitch level, G4–C4.





CHORD—SCALE RELATIONSHIP: MODES




* * *



Figure 18.4 provides a chord—scale relationship for “Confirmation” using modes only.

Although the rate of harmonic rhythm is relatively fast (with the ubiquitous II–V progressions), each measure contains only a single mode. In establishing chord—scale relationships for other chords, we need to determine their function, analyze their quality, and choose an appropriate mode that fits the underlying harmonic context. For instance, each tonic chord occurring in the tune establishes a chord—scale relationship with the Ionian mode only. Although Lydian and Lydian Augmented could potentially have been used as substitute scales, they would have been too chromatic in the context of this tune and within the realm of bebop style. The underlying motion from I–IV is rooted in the blues tradition and the selection of modes for the subdominant in m. 5 is in keeping with that tradition. Even though the subdominant on IV features a dominant 7th chord, in the context of this progression it functions as a predominant.



FIGURE 18.4 Chord—Scale Relationship: Modes

There are two ways of establishing a chord—scale relationship for ii7–V7 or –V7 progressions: either select a mode that works for V7 or select a mode that works for ii7 or ()). As shown in Figure 18.4, mm. 2–4 feature a descending sequence of incomplete II–Vs connecting the tonic on I with the predominant on IV. Each II–V progression establishes a chord—scale relationship with the corresponding dominant 7th. Notice that, in m. 2, the use of Mixolydian ♭13 fits the underlying context much better than the diatonic Mixolydian mode. The tonic note F4 functions as the ♭13th of Mixolydian ♭13 and is retained as a common tone in mm. 1–2. The second A section (mm. 9–16) demonstrates a different approach to chord—scale theory. The selection of modes for the II–V progression in Figure 18.4 is based on the quality of the predominant chord. Thus, in m. 10, Emin7(♭5)–A7 uses E Locrian, while in m. 11, Dmin7–G7 establishes a chord–scale relationship with D Dorian, etc.

The bridge of “Confirmation” (mm. 17–24) features two four-bar phrases with ii7–V7 tonicizations of the IV and ♭VI key areas. The chord—scale relationship for the bridge in Figure 18.4 includes a different selection of modes: Dorian, Mixolydian, and Ionian for min7–F7–B♭Maj7, and Dorian, Altered, and Lydian for E♭min7–A♭7–D♭Maj7. Tonal and contextual considerations are particularly evident with the choice of Altered mode in m. 22, which accommodates notes from the tonic key and prepares the arrival of FMaj7 in m. 25. The last A section (mm. 25–32) features a much bolder selection of modes.

The choices of A Altered in m. 26 and F Locrian in m. 28 are particularly poignant. The former injects chromatic notes into the structure of dominant 7th chord. The choice of F Locrian over Cmin7–F7 in m. 28 might seem out of place because neither chord (at least not in the present form) establishes a convincing relation ship with this mode. But, the F Locrian mode forms a chord—scale relationship with F7sus, which is an effective harmonic substitution for Cmin7–F7.

While the selection of modes in Figure 18.4 is overcrowded with different options, an improvisation may focus on only a few modes. In fact, each A section contains a selection of modes that could be implemented in the course of an entire solo. In establishing a successful chord—scale relationship for the tune, be mindful of three important considerations: (1) modal hierarchy, (2) chromatic treatment, and (3) voice leading. Chromatic modes, for instance, contain notes that might need preparation. This preparation usually takes place anywhere from one beat to one measure before the chromatic notes occur. The succession of modes in mm. 5–6—B♭ Mixolydian and D Mixolydian ♭13—illustrates such a case. The latter mode contains the chromatic ♭13th that was introduced as ♭7th of B♭7 in m. 5.





CHORD—SCALE RELATIONSHIP: BEBOP SCALES




* * *



Figure 18.5 provides a chord—scale relationship for “Confirmation” using bebop scales only.

The selection of bebop scales is analogous to the use of modes from Figure 18.4. In m. 2, for instance, Emin7(♭5)–A7 uses A Mixolydian ♭13, which accommodates in its pitch structure, as does A dominant bebop ♭13, making them much better choices than their diatonic counterparts.

Demonstrating slightly different and more advanced organization of bebop scales, the last A section alternates between ascending and descending scalar patterns. In addition, the last note of each measure forms a stepwise connection with the first note of the next, thereby ensuring effective voice leading between different scales. Thus the last note of m. 26, C♯4, resolves up to D4, which begins the G dominant bebop scale on 5. Similarly, the use of B♭3 in m. 31 is a consequence of the C4 in m. 30 resolving down to the ♭7th of C7.

“I GOT RHYTHM” CONTRAFACTS




* * *



With the exception of the blues, the rhythm changes progression is probably the most important chord progression in jazz. The term “rhythm changes” refers to a 32-bar AABA form based on the harmonic structure of “I Got Rhythm” by George and Ira Gershwin. The song appeared in the Aarons and Freedley production Girl Crazy (1930) and originally featured a 34-bar AABA form with a two-bar extension in the last A section. The two-bar extension was eventually cut and the chord changes of the last A section replicated those from the second A. A newly composed line based on the rhythm changes progression is known as a contrafact. The enormous popularity of rhythm changes has been well documented by an ever-increasing number of composed contrafacts and recordings.1





“MOOSE THE MOOCHE”—AN ANALYSIS




* * *



Charlie Parker wrote a number of contrafacts on rhythm changes among which “Moose the Mooche,” shown in Figure 19.1, is one of the most well known.2





Form and Harmony


“Moose the Mooche” features a 32-bar AABA form.3 The first A section is harmonically open and ends on a ii7–V7 in m. 8. The second A features a full-cadential closure on I in m. 16. The bridge cycles through a cycle of dominant 7ths progression and interrupts the form on V7 in m. 24. The final A section is harmonically closed but, in order to allow for the circularity of the chorus improvisation, it features a Imaj7–VI7–ii7–V7 turnaround progression (or any acceptable substitute variant).

The tonic is prolonged in mm. 1–4 and then morphed into a V7/IV in m. 5. The tonic prolongation takes the form of an idiomatic Imaj7–vi7–ii7–V7 progression, which lends itself to a variety of harmonic substitutions. The subdominant controls mm. 5–6 and is capable of many surface realizations. Next, mm. 7–8 proceed to the dominant, which can also be idiomatically expanded, transformed, and/or confirmed. The A section of rhythm changes is also known as an eight-bar blues because it contains the harmonic paradigm of the blues: tonic in m. 1, subdominant in m. 6, and dominant in m. 8.4 This foreshortened blues preserves the structural weight of the fundamental chords, as the tonic controls the longest span (mm. 1–4), the subdominant occupies the shorter span (mm. 6–7), and the dominant (m. 8) becomes subject to various harmonic modifications.





Melody and Rhythm


The melody of “Moose the Mooche” confirms the premise that contrafacts are far more dexterous than the tunes from which they borrow their chord progressions. The melodic rhythm of “Moose the Mooche” is typical of bebop syntax. In m. 1, the Charleston rhythm is highlighted with an octave leap from F4 to F5. This rhythmic gesture appears in various guises throughout the tune. Other rhythmic figures, such as 8th-note triplets in mm. 2 and 8, and 16th-note triplet turn figures in mm. 14, 31, and 32, are idiomatic decorations that enhance the melodic surface.

The presence of chromaticism is integral to the structure of bebop melodies. Some of the chromatic additions, such as the metrically accented C♯5s in mm. 2, 6, 26, and 30, make subtle references to the blues. Other chromatic notes emphasize structurally important harmonies. For instance, a carefully prepared A♭4 occupies beat 1 in mm. 5 and 29, and constitutes the ♭7th of the underlying V7/IV harmony. The preparation of A♭4 in mm. 4 and 28 features an upward stepwise ascent: F4–G4. The end of m. 12 illustrates another idiomatic preparation of this pitch. Here, the A♭4 anticipates V7/IV by a half beat and occurs at the “and” of 4 in m. 12. The downward tritone leap from D5-A♭4 further intensifies its status and injects yet another blues characteristic into the framework of the melody. Other chromatic notes, such as unaccented passing and pitch enclosures, have primarily ornamental functions. The chromatic passing note G♭4 in mm. 5 and 29 moves between and . A chromatic pitch enclosure occurs in m. 18 when the melodic cell E4-C4-C♯4-D4 encircles the root of D7. The C♭5s in mm. 2, 6, 26, and 30 constitute melodic appoggiaturas because they are accented and approached by a leap.



FIGURE 19.1 Lead Sheet—“Moose the Mooche”

The rhythmic structure of the melody is interesting hypermetrically: in mm. 1–4, the hypermetric downbeat occurs in mm. 1 and 3 and emphasizes as the melodic anchor. The continuation of the phrase features a less regular hypermetric organization with metrical downbeats occurring in mm. 5, 6, and 7. This hypermetric organization cor — roborates yet another characteristic of contrafacts, namely that they have a fairly irregular and purposefully unpredictable phrase structure. The irregular hypermetric organization of the A section is balanced by a symmetrical unfolding of hypermetric two-bar phrases in the bridge.





AN ANALYSIS OF THE TRANSCRIPTION




* * *



Hank Jones’s solo on “Moose the Mooche” comes from the album Bebop Redux, recorded in 1977 (see Figure 19.2).

In the span of five choruses, Jones offers a logical and coherent musical statement that demonstrates his fine improvisational skills and excellent command of bebop vocabulary. One of the defining features of the solo is the overall simplicity and creative treatment of the original melody. In the head shown in Figure 19.1, is an important melodic anchor that is metrically and rhythmically reinforced. In his solo, Jones uses this pitch at different locations and over different harmonic/melodic contexts. For instance, in m. 1 an octave leap F4–F5 makes a clear reference to the original tune. Three choruses later in m. 97, the same melodic gesture comes back and is bolstered with octaves. In mm. 128–130, the melodic phrase with a 3/4 cross rhythm embellishes .

As pointed out in the analysis of the tune, blues melodic devices are featured prominently in the original melody. In Jones’s solo, the melodic blue notes are integral components of his lines. In mm. 14–15, for instance, the pitch D♭4/C♯4 connects two adjacent phrases: ♭ functions as a ♭7th of E♭7 and then becomes a lower chromatic neighbor preparing the 3rd of B♭Maj7 in m. 15. The tritone G4-D♭4 in m. 14 provides additional blues references. In mm. 61–62, open-position chords have similar blues underpinnings with ♭ as the highest note piercing through the characteristic blues voicing. In mm. 94–95, the use of three-note close-position voicings embellished with grace notes enhances the structural subdominant.

What is truly remarkable about the melodic design of Jones’s lines is their overall simplicity. Jones does not shy away from simple triadic ideas (mm. 63, 65, 122, 127, and 155). In each case, they are performed with rhythmic precision, convincing articulation, and good rhythmic feel, and are perfectly integrated in the context of his lines. He elaborates these triadic ideas with a variety of passing notes (mm. 25–26, 89–90, 91, 105, and 153).

Another relatively simple technique used by Jones in his solo involves the arpeggiation of four-part chords. Although straightforward versions of this technique might seem formulaic, when integrated convincingly in the context of melodic lines and played with a good time feel, they can add much-needed clarity to the overall flow of the solo. In m. 17, for example, a rootless Amin9 beginning on the 9th initiates the bridge; in m. 39, a downward arpeggiation of Gmin7 on beats 3 and 4 foreshadows a more chromatic conclusion of the phrase; in m. 92, a downward arpeggiation of Cmin7 balances an upward arpeggiation of a rootless B♭9 in m. 93; in mm. 115–116, an incomplete upward arpeggiation of Dmin11 balances a downward arpeggiation of G7(♭13) implementing the G augmented triad that spans an octave and a half. In mm. 141–143, the use of arpeggiation is elevated to a new level of rhythmic/harmonic complexity as Cmin7, B°7, Cmin7/B♭, Gmin7, F♯°7, Gmin7/F, and E♭°7 expand the underlying B♭7-E♭Maj7-B♭Maj7-F7 progression using 3/8 cross rhythms.





FIGURE 19.2 “Moose the Mooche”—Improvised Solo by Hank Jones (transcribed by Dariusz Terefenko)

In the analysis of “Confirmation” in Chapter 18, I pointed out that Jones’s playing reveals an affinity toward favored melodic gestures and/or chord-scale relationships. In this solo, similar observations can be made. One of the most obvious examples of Jones’s penchant for well-internalized devices occurs in mm. 21–22 of the form. The lines in mm. 21–22, 53–54, and 85–86 establish a chord-scale relationship between C7 and Mixolydian ♯11. This relationship is, of course, highly idiomatic of bebop performance practice.

Notice also how Jones balances the contour of his phrases with a measured use of stepwise melodic motion and arpeggiation. For instance, in mm. 65–66 the phrase begins with a downward arpeggiation, then integrates a –♭– –♭–chromatic descent, which fulfills the condition for adding extra chromatic notes, and finishes off with an upward melodic leap to the E♭5-G5 dyad. In mm. 77–80, the line begins with a stepwise embellishment of using upper neighbors and escape notes and, by mm. 79–80, morphs into straightforward arpeggiations of F7 and Cmin7, respectively.





HARMONIC REWORKINGS OF RHYTHM CHANGES




* * *



The A section of rhythm changes can be realized with different harmonic progressions. Some of the most interesting realizations are shown in Figure 19.3a–i. With each consecutive progression, the level of harmonic complexity increases.

When comparing mm. 1–2 with mm. 3–4, which essentially feature similar tonic expansions, B♭Maj7/D, D7(♭9), Dmin7, B♭7, DMaj7, B♭Maj7/F or D7 at the beginning of m. 3 can be used to replace the original tonic chord B♭Maj7. In comparing the substitute options for the submediant in m. 1 or the supertonic in m. 2, there is also a variety of available choices. Figure 19.3e–i demonstrates more advanced transformations of the original progression. In Figure 19.3e, the submediant in m. 1 (Gmin7) and the supertonic in m. 4 (Cmin7) are replaced with the dominant tritone substitutions (D♭7(♭5) and G♭7, respectively). Figure 19.3f combines the incomplete major-third cycle in mm. 1–2 with the descending major-second cycle in mm. 3–4. Figure 19.3g experiments with the “Coltrane” substitutions. In Figure 19.3h, a dominant pedal point supports the chord progression in upper parts. In Figure 19.3i, an extended cycle of dominant 7ths beginning on ♭ substitutes for the original progression.

The bridge of rhythm changes can be realized in many different ways as shown in Figure 19.4a–h.





FIGURE 19.3 Alternate Progressions for the A Section





FIGURE 19.4 Alternate Progressions for the B Section

All the harmonic options in Figure 19.4 rely on the use of dominant 7th tritone substitutions, ii7–V7 diminutions, and/or [ii7–V7]/X interpolations. The use of a dominant 7th tritone substitution in its clearest manifestation is shown in Figure 19.4b. Chords in mm. 18, 20, 22, and 24 function as tritone substitutions of the preceding dominant 7ths. The use of ii7–V7 diminutions results in the faster harmonic rhythm, as each dominant 7th of the bridge can be potentially expanded with a predominant ii7. In Figure 19.4c, the ii7–V7s occurring in mm. 18, 20, 22, and 24 expand the underlying dominant 7th chords. The combination of ii7–V7 diminutions with [ii7–V7]/X interpolations can produce more intricate harmonic progressions as demonstrated in Figure 19.4d and 19.4e. The most obvious consequence of such combinations is even faster harmonic rhythm with two chords per measure. For instance, in Figure 19.4d, the [ii7–V7]/X interpolations in mm. 18, 20, 22, and 24 establish a logical voice-leading connection with the upcoming ii7–V7 progression. In addition, the ii7–V7s in mm. 17–18, 19–20, 21–22, and 23–24 are a half step away from each other, which further assures good voice leading. The neighboring ii7–V7s are also on display in Figure 19.4e. But unlike Figure 19.4d, the [ii7–V7]/X progressions in mm. 18, 20, 22, and 24 from Figure 19.4e function as lower chromatic neighbors in relation to the diatonic ii7–V7 progressions.





RHYTHM CHANGES IMPROVISATION




* * *





The A Section: A Single-Scale Approach


The chord structure of the A sections of rhythm changes can be reduced to the fundamental framework shown in Figure 19.5.

While mm. 1–4 of any A section feature a tonic prolongation, mm. 5–8 are more complicated even at the background level. For instance, the predominant in mm. 6, 14, and 30 can take the form of major 7th or dominant 7th chords. Also, the tonally closed second A section features two bars of Imaj7 in mm. 15–16 instead of a half cadence in mm. 8 and 32. Figure 19.6 establishes a chord-scale relationship between structural chords and bebop scales.



FIGURE 19.5 Fundamental Harmonic Frameworks



FIGURE 19.6 A Basic Chord-Scale Relationship for the A Section

With a single major bebop scale controlling mm. 1–4, we can concentrate on improvising melodic lines that are entirely derived from the B♭ major bebop scale without being too preoccupied with the surface chord changes. In fact, when improvising against a more complex harmonic accompaniment, the melodic lines—albeit with a single chromatic passing note and the diminished 7th chord—will balance the chromatic accompaniment with controlled melodic tensions. Since mm. 5, 13, and 29 tonicize the subdominant harmony, this harmonic event needs to be well planned, prepared, and executed. Take the clue from the original melody and see how Parker introduced ♭ in those measures. In short, ♭ is an essential pitch that is necessary to make a convincing transition from the tonic to the predominant key area. Figure 19.7a–c demonstrates how to negotiate the A section of rhythm changes using the chord-scale relationship from Figure 19.6.





The A Section: A Two-Scale Approach


The next step in rhythm changes improvisation involves adding a dominant 7th bebop scale in mm. 2 and 4. As a result, we must now negotiate two chromatic notes, ♭ from major bebop and ♯ from dominant bebop. These additions will considerably chromaticize the content of melodic lines. Except for m. 6, mm. 5–8 remain the same as in Figure 19.5; the subdominant is expanded with a passing diminished 7th on ♯. Figure 19.8 provides a chord-scale relationship for the A section of rhythm changes.

Figure 19.9a–c demonstrates a melodic realization of the chord-scale relationship from Figure 19.8.



FIGURE 19.7 Melodic Embellishments of the A Section



FIGURE 19.8 An Alternate Chord-Scale Relationship for the A Section





The A Section: Chord Arpeggiations


Having introduced two scalar choices for mm. 1–4, we can now focus on improvising over more harmonically advanced A sections with various arpeggiations of four- and five-part chords. These options are shown in Figure 19.10a–e with different harmonic settings for the A section.

The use of arpeggiation capitalizes on good voice leading between adjacent chords. When examining the content of lines in Figure 19.10b–e, notice that the low (or high) notes that begin arpeggiation patterns create a stepwise line spanning the entire A section. Such a line uses common tones and/or features stepwise motion between adjacent chords.





The B Section: A Single-Scale Approach


With only dominant 7th chords, the bridge of rhythm changes has a relatively uniform chord-scale relationship. Figure 19.11 establishes a basic chord-scale relationship for the B section. The use of D dominant bebop ♭13 at the beginning of the bridge is in keeping with the overall tonality of rhythm changes.

Figure 19.12a–c provides a melodic realization of the chord-scale relationship from Figure 19.11.

METHODOLOGY




* * *



A thorough understanding of chord—scale theory allows us to prioritize certain notes and de-emphasize others. Hierarchically important notes occurring in the context of harmonic progressions and melodic lines (beauty marks, chord tones, alterations, and extensions) should receive melodic, harmonic, and rhythmic stress. Avoid notes, meanwhile, require careful metric and voice-leading considerations, because their uncontrolled presence might affect the clarity of chord progressions and melodic lines. In the structure of seven-note modes, there is a distinct hierarchy among pitches: the use of 4 in Ionian or 5 in Lydian, for instance, might have an undesirable effect on the content of corresponding chords or lines. The exclusion of these notes from Ionian and Lydian (and other notes from other modes as well) creates intervallically diverse six-note hexatonic scales (i.e. scales of cardinality of six). The removal of two notes from seven-note modes produces even more intervallically diverse five-note pentatonic scales (i.e. scales of cardinality of five). The intervallic variety of pentatonic and hexatonic scales is very attractive to the improviser. The seven-note modes, scalar transpositions of a melodic pattern tend to sound predictable after a few repetitions. In pentatonic or hexatonic collections, however, the same pattern often sounds less predictable because the intervallic content of these scales is much more diverse. The reduction of pitch content to only five or six essential tones highlights the most crucial notes from the mode and imbues them with the capacity to make chords or melodic lines sound convincing.

The development of pentatonic and hexatonic systems is analogous to the methodology of mode classification discussed in Chapter 7 and chord—scale theory in Chapter 8. Pentatonics and hexatonics are placed in functional categories and analyzed for their melodic and harmonic potential.





PENTATONICS




* * *



In jazz, pentatonics represent a rich assortment of scales with a vast potential for improvisation. They come in a variety of flavors, from the simple blues inflections added to diatonic pentatonics popularized by Lester Young in the 1930s to the chromatically altered five-note segments common in contemporary jazz styles.1





Basic Pentatonics


There are three basic pentatonics: major, minor, and dominant.2 Major pentatonic, shown in Figure 20.1, is derived from the Ionian mode excluding 4 and 7.

The absence of semitones from its structure affects the scale’s tonal character and removes the traces of harmonic tension from the collection. When listening to the sound of this scale, it conveys an aura of tonal neutrality, which makes major pentatonic, and other pentatonics as well, ideal choices for modal improvisation and modal harmony.



FIGURE 20.1 Major Pentatonic


Minor pentatonic is derived from the Aeolian mode by excluding the tritone between 2 and ♭6. Figure 20.2 illustrates the derivation of a minor pentatonic.

The content of a minor pentatonic prioritizes the intervals of major 2nds and minor 3rds, just as in the major counterpart. Similar to major pentatonic, the absence of the tritone and the leading tone contributes to the scale’s independent tonal status.

Figure 20.3 illustrates two types of dominant pentatonic scale: dominant and suspended. Both can be derived from the Mixolydian mode and, as such, establish a convincing chord—scale relationship with the dominant 7th and suspended dominant chords respectively.

The pitch content of dominant pentatonic includes the tritone between 3 and ♭7 that is inherent to the structure of the scale. The omission of 6 prevents the occurrence of a minor 2nd. This is in keeping with the overall character of other pentatonic collections.



FIGURE 20.2 Minor Pentatonic




FIGURE 20.3 Dominant and Suspended Pentatonics


The intervallic content of suspended pentatonic prioritizes major 2nds and minor 3rds and the inclusion of 4 enables a chord—scale relationship with corresponding suspended formations.





Diatonic Pentatonics


In Chapter 7, diatonic and chromatic modes were generated using rotations of two parent scales: the major to construct diatonic modes and the melodic minor to create chromatic modes. Diatonic pentatonics can be derived in a similar manner. For the derivation of diatonic pentatonics, Dorian pentatonic is employed as the parent scale. The reason for this selection stems from its symmetrical pitch organization.3 Figure 20.4 illustrates the pitch structure of the Dorian pentatonic.

Unlike other pentatonics discussed thus far, the Dorian pentatonic has a much more diverse intervallic content and includes four distinct intervals: two major 2nds, a minor 2nd, a major 3rd, and a minor 3rd (when you wrap the scale around the octave). Although reduced to only five notes, the pitch content of the scale embodies the essential Dorian characteristics: it has minor qualities and includes the beauty mark, major 6th.

By rotating the pitch structure of Dorian pentatonic, five distinct pentatonics are created: Phrygian, Lydian, Mixolydian, Aeolian, and Locrian. These scales are referred to as diatonic pentatonics. The Ionian pentatonic is excluded since it was previously introduced in Figure 20.1 as a major pentatonic. Figure 20.5 illustrates these five rotations of a Dorian pentatonic.

The Phrygian pentatonic starts on 2, the Lydian pentatonic begins on ♭3, the Mixolydian pentatonic starts on the non-existent 4, the Aeolian pentatonic originates from 5, and the Locrian pentatonic begins on 6. When transposing these pentatonics to the same starting pitch, all but Mixolydian begin on the same note. The Mixolydian does not since its pitch content is built on the non-existent root of the scale 4. When comparing the structure of Mixolydian and Aeolian from Figure 20.5, notice that they have the same pitch content. The difference between the two becomes apparent when comparing their transpositions. Figure 20.6 shows six pentatonics transposed to C4.

Based on what is already known about the modal theory, observe that the diatonic pentatonics have the same salient features as the corresponding seven-note modes. The Phrygian pentatonic contains the beauty mark ♭2, the Lydian pentatonic includes ♯11, and the Mixolydian pentatonic contains all the essential notes from the dominant 7th formation. The Aeolian pentatonic features the beauty mark ♭6, and the Locrian pentatonic highlights the characteristic ♭5.

Chromatic Pentatonics


Figure 20.7 shows how the Melodic Minor pentatonic can serve as the parent scale for the generation of chromatic pentatonics.

Figure 20.8a illustrates the rotations of the chromatic pentatonics and Figure 20.8b transposes them to C4.

After transposing chromatic pentatonics to C4, the Dorian ♭2 and Mixolydian ♯11 pentatonics begin on ♭2 and 2 respectively.4

FIGURE 20.8B Pentatonics Transposed to C4





Altered Pentatonics


The structure of diatonic and chromatic pentatonics can be modified by minor pitch displacements and/or chromatic alterations. These pitch modifications result in the creation of the altered pentatonics; these scales share essential qualities with the regular pentatonic scales that they purport to modify. Figure 20.9 compiles altered pentatonics and shows their relationships with the diatonic and chromatic pentatonics.

With the exception of the Mixolydian pentatonic, altered versions of diatonic pentatonics include different combinations of pitches derived from the corresponding modes. Mixolydian I and Mixolydian II include chromatic alterations of 2; these result in the inclusion of ♭9 in the former, and ♭9 and ♯9 in the latter.5





FIGURE 20.9 Altered Pentatonics





THE PENTATONIC SYSTEM




* * *



Broadly speaking, there are three types of pentatonic scale: diatonic, chromatic, and altered. The diatonic and chromatic pentatonics can be derived from the Dorian and Melodic Minor pentatonics, respectively. Altered pentatonics result from minor pitch displacements and/or alterations of diatonic and chromatic pentatonics. Even though pentatonics are primarily associated with modal improvisation and modal harmony, it is possible to invoke traditional functional relationships to make them useful in tonal improvisation and harmony as well. The pentatonic system attempts to illustrate the tonal potential of different pentatonic collections. To facilitate this discussion, the diatonic, chromatic, and altered pentatonics are compartmentalized into the familiar functional categories.

Harmonic Potential


Pentatonic collections are very useful for the generation of so-called quartal voicings. Although voicings introduced in this section primarily have modal characteristics, they are just as effective in the tonal contexts. Figure 20.15 demonstrates five quartal voicings that can be derived from the Dorian pentatonic. In this and the forthcoming figures, boxed chords indicate the projection of a complete pentatonic collection.

The structure of the voicings in Figure 20.15 features the notes from the Dorian mode arranged as stacked fourths.6 Even though occasional thirds or other intervals might appear in quartal voicings, they tend to balance the overall structure of the sonority. As long as the interval of a fourth is prioritized (especially at the bottom of the chord), voicings should display typical modal characteristics.

The methodology for generating pentatonic voicings can be summed up as follows:

1.Create a quartal voicing that includes all or the majority of the pitches from the pentatonic collection.

2.The pitches from the pentatonic scale function as the roots of the subsequent chords derived from this pentatonic.

3.Transfer the opening voicing up to the next pitch from the pentatonic scale unfolding in the bass. Think of transferring all the voices (excluding the bass voice) up to the next available pitch derived from the corresponding seven-note mode. In generating Phrygian pentatonic voicings, for instance, use a Phrygian pentatonic to create five unique transpositions of the opening sonority and the Phrygian mode to supply the pitch content.

4.While the lowest note of each voicing projects the specific pentatonic scale, the inner voices are derived from the corresponding mode.

5.These voicings represent a useful collection of sonically related formations that can be used interchangeably in a variety of tonal or modal contexts.

FIGURE 20.15 Dorian Family of Voicings


Figure 20.16 illustrates the families of pentatonic voicings for selected basic, diatonic, chromatic, and altered pentatonic collections.





Melodic Potential


Even though the methodology described above focuses on voicings, the idea that chords can be horizontalized as lines, and vice versa, allows us to explore the melodic potential of pentatonics. Figure 20.17 shows how it is possible to extract three-note melodic cells from a given pentatonic and then how to use those cells to create a pentatonic line.

These pitch transfers preserve the overall shape of the original cell, but not always the intervallic contour of the cell. The diverse intervallic structure of pentatonics is very useful in rendering different pitch transfers of the original motive less symmetrical and devoid of intervallic predictability.

HEXATONICS




* * *



The hexatonic scale is a six-note collection that conveys characteristics similar to the seven-note modes. Just like pentatonics, hexatonic scales have more interesting intervallic properties and provide essential notes for melodic lines and harmonic formations. The hexatonic collections are compartmentalized in the familiar categories and scales are generated from aggregates of pitches that contain all available notes from the particular category. For instance, since the pitch aggregate for the major category contains eight notes, there are a number of options for creating different major hexatonics. Given the enormous range of options, it is best to pick a scale whose pitch content best conveys specific modal characteristics.

The derivation of hexatonics from the aggregate puts the understanding of pitch hierarchy to the test. The pitch structure of different hexatonics prioritizes only those notes that are essential to projecting the exact harmonic function and/or intended chord—scale relationship. Each category below includes two types of hexatonic collection: regular and altered. Regular hexatonics share common characteristics with the corresponding modes. For instance, Mixolydian ♯11 hexatonic has similar properties to the seven-note Mixolydian ♯11 mode, etc. Altered hexatonics are derived from the specific pitch aggregate and their structure includes minor variations from regular hexatonics. In labeling altered hexatonics, use the name of the category with Roman numerals specifying different variations (i.e. Major Altered I, Dominant Altered II, etc.).





Major Category


Possible Harmonic Function—Tonic and Predominant

Figure 20.18 illustrates the pitch aggregate for the major category: three regular hexatonic collections and three altered hexatonics.7 The only notes that cannot be used in the aggregate are ♭2, ♭3, and ♭7. All other notes as six-note segments can be freely combined to create altered hexatonics. Notice that the Major Altered II and III combine the characteristics of three regular hexatonics (5 from Ionian, ♯4 from Lydian, and ♯5 from Lydian Augmented).





Minor Category


Possible Harmonic Function—Tonic and Predominant

Figure 20.19 provides the pitch aggregate for the minor category: three regular hexatonic collections and three altered hexatonics. The inclusion of ♯4 in the aggregate raises several issues. Until now, the ♯4 (♭5th) has participated only in the context of major or dominant chords. In more advanced harmonic practice, however, the addition of ♯4 (functioning as a ♯11th) expands the structure of minor formations. Since the extended tertian structure derived from C Melodic Minor, for instance, features two overlapping four-part formations, Cmin(♭7) and Bø7, the upper formation can be substituted with the Bmin7 chord. This substitution preserves the tertian nature of the extended formation and infuses the seven-part chord with the Lydian characteristics: C–E♭–G–B–D–F♯–A.

Figure 20.20 shows the pitch aggregate for the dominant category: four regular hexatonic collections and four altered hexatonics. The only pitches excluded from the aggregate are 4 and 7. Notice the presence of Mixolydian ♭9, which was not encountered in the discussion of modal theory. Since this scale includes a single chromatic alteration ♭9—just as the two other chromatic modes, Mixolydian ♯11 and Mixolydian ♭13—this collection is labeled as Mixolydian ♭9.

Harmonic Potential


Just as with pentatonics, the hexatonic collections provide useful pitch resources for creating interesting voicings of different cardinality. The procedures for generating voicings of various sizes are similar to those discussed earlier in this chapter and utilize transfers of the initial voicing through the hexatonic scale. The resulting five voicings represent the sound of the specific hexatonic and are potential substitutes for one another in different harmonic scenarios. Hexatonic voicings can be generated using the following procedures:



FIGURE 20.23 Hexatonic Voicings


1.Establish the initial close-position voicing that captures the sound of the hexatonic scale.

2.Transfer the close-position voicing up to the next pitch from the hexatonic scale. Use notes from the corresponding hexatonic scale only.

3.Rearrange the pitches of the initial close-position voicing to create different open-position formations.

4.Transfer the open-position voicing through the hexatonic scale.

Figure 20.23 demonstrates these procedures using four- and five-part voicings derived from Lydian hexatonic.





Melodic Potential


Based on the fundamental premise that chords can be linearized and lines can be verticalized, hexatonic scales can be explored by using different melodic cells. These cells are derived from the scale’s content and transferred to all the notes from the corresponding hexatonic collection. The subsequent pitch transfers feature more intervallic variety within them, as was the case with pentatonic scales in Figure 20.17. Figure 20.24 demonstrates this process.



FIGURE 20.24 Melodic Potential


NOTES



* * *



1. See, for instance, Lester Young’s The Kansas City Sessions and The Complete Aladdin Recordings.

2. The major, minor, and “suspended” pentatonics are rotations of one another and are basic to modern jazz practice.

3. From ca. 800 until the 1500s, Dorian was considered the first mode in the eight-mode system. As a palindrome, Dorian has the same intervallic structure upwards and downwards.

4. Since the Mixolydian ♭13 pentatonic does not contain ♭7 in its structure, it is omitted from the list of available chromatic pentatonics.

5. The use of Roman numbers “I,” “II,” etc. indicates the pitch variations of the basic, diatonic, or chromatic pentatonics.

6. These types of voicing are also known as so-called “So What” voicings because they resemble similar chords performed by Bill Evans on the iconic Kind Of Blue recording from 1959.

7. Since hexatonic collections and modes share the same chord—scale relationships, the forthcoming figures do not include chords.

PHRASE PROTOTYPES




* * *



The phrase structure of standard tunes is fairly predictable.1 It consists of a finite number of mostly eight-bar phrases that are easily classified according to their melodic, harmonic, and contrapuntal properties.2 Melodic properties, for instance, are characteristic successions of melodic tones common to particular families of standard tunes. The same can be said about harmonic and contrapuntal features. The supporting harmonies are constrained by certain principles of chord formation and by various rules of counterpoint and harmonic function. These relationships are demonstrated using the concept of phrase models. Although phrase models are classified according to the differences in the melodic structure and supporting harmonies, it is important to stress that these properties are mutually intertwined. The behavior of the melody is shaped by its supporting harmonies, just as the sense of harmonic progression is dictated by the behavior of melodic patterns.3 This intimate relationship means that if we attempt to understand the phrase structure of standard tunes in exclusively melodic terms or from a purely harmonic perspective, that understanding will be incomplete.

In the discussion of II–V–I in Chapter 6, a distinction between different rhetorical types and the functional role of the progression was made. Phrase models, aside from their melodic, harmonic, and contrapuntal characteristics, can also be described in terms of their rhetorical layout. Typically, a phrase model has three main parts: phrase identifier, harmonic departure, and cadential confirmation. A phrase identifier is a short harmonic progression with two, three, or four chords that appears at the beginning of a phrase and gives the entire phrase its harmonic identity. Given the pliability of jazz harmony—especially its huge transformative potential—phrase identifiers occur in various substitute forms without actually changing the status of the phrase model. Since each phrase model has a different phrase identifier, it is considered the most recognizable feature of the model.

Harmonic departures typically occur in the middle of a phrase and feature different diatonic or chromatic interpolations as well as tonicization of closely or distantly related key areas. Given the plethora of available harmonic options, this section of a phrase model is the most ambiguous and challenging to codify. In the context of the prototypical phrase model, then, the exact location and type of harmonic departures are ultimately related to the design of the melody and the type of underlying chord progressions.

In contrast to the inherent ambiguity of harmonic departures, the harmonic implications of the cadential confirmations are fairly straightforward. The cadential confirmation is a progression—typically a complete/incomplete II–V or its common harmonic variants—that concludes a phrase model. Depending on the rate of harmonic rhythm, cadential confirmations typically occur in m. 8 or mm. 7–8 of an eight-bar phrase. Figure 21.1 shows a generic phrase model with three structural components: phrase identifier, harmonic departure, and cadential confirmation.

The hierarchy among chords is indicated with different note stems and flags connected to the beam. Slurs group chords comprising the phrase identifier. Dashed slurs illustrate cadential confirmations. Brackets indicate the space occupied by harmonic departures. The two empty measures in Figure 21.1 are reserved for a harmonic departure that is unique to the structure of a particular tune. The beam connects chords belonging to the phrase identifier and cadential confirmation features a complete cadential closure.



FIGURE 21.1 Generic Phrase Model


Normally, all three components of the phrase model are present but, under special conditions, a phrase model can be truncated. The B section of a tune with a complex harmonic setting may, for instance, utilize only parts of the phrase model without cadential closure or harmonic departure. This type is referred to as an incomplete phrase model.

Phrase models provide background harmonic frameworks for the tonality of standard tunes. These models draw on traditional tonal features, such as root movement by fifths, monotonality, stepwise motion of the supporting counterpoint, and the T–PD–D–T chord succession. Let’s briefly revisit these features and examine the ways in which they explain the tonality of standard tunes. A root movement by fifths is the overarching characteristic of tonal music. With a single tonic at the center of tonality, all other chords are dependent on the tonic. Chord progressions, especially those with the structural visibility (i.e. ii7–V7–Imaj7), follow the traditional root movement by 5ths, the most fundamental harmonic motion defining tonality and tonal relationships.4 This motion exemplifies the succession of harmonic functions from the instability of the dominant to the stability of the tonic or—at the background level—controls the proper distribution of the secondary key areas. Even though other root movements may (and frequently do) occur, they are hierarchically dependent on fifth motion and can even be derived from it. Since the tonal system places a single tonic at the center of all melodic, harmonic, and contrapuntal activity, the concept of monotonality is central to tonality. Even though certain tunes might begin in apparently different keys, such as “I Hear a Rhapsody,” “All the Things You Are,” “Autumn Leaves,” and many others, they ultimately lead to the home key. This is firmly confirmed by a cadence featuring a root movement by fifths.

Counterpoint is a driving force that propels different harmonic progressions to their destinations. In the context of standard tunes, the term “counterpoint” is applied to signify the behavior of guide tones within chord progressions and to indicate the overall characteristics of voice leading. Since the behavior of counterpoint is predictable yet quite flexible, it is a powerful agent influencing the interaction of melodic lines and chord progressions. Figure 21.2a–b illustrates the harmonic flexibility of a counterpoint using a –– melodic pattern. These distinct harmonic realizations employ root movement by fifths, use a stepwise motion in inner voices, and demonstrate the transformative power of counterpoint. Even though the rules of counterpoint in both harmonizations are exactly the same, the respective outcomes, however, could not be more different.

Figure 21.2a illustrates the harmonic realization of a –– melodic pattern using a diatonic Imaj7–ii7–V7–Imaj7 progression. Figure 21.2b demonstrates a more intricate realization of the same melodic pattern. After the initial support from the tonic chord, in Figure 21.2b is reinterpreted as a ♭5th of the F♯min7(♭5) chord, which launches the sequence of fifth-related progressions before converging on the final tonic chord. The harmonic space between the two tonic chords in Figure 21.2b is heavily elaborated with different diatonic and chromatic formations. One of the most striking features of Figure 21.2b is that it preserves the same basic rules of tonal voice leading and harmony as Figure 21.2a. The intervening chords do not violate any traditional rules of tonal voice leading and harmony; they do not, for example, create parallel perfect 8ves and 5th with adjacent chords—not that parallel perfect 8ves and 5th are unwelcomed in jazz syntax—nor do they violate the rules of functional syntax. Since the harmonic realization of the –– pattern in Figure 21.2a satisfies the traditional rules of tonal voice leading and harmony, and the processes of transformation preserve those rules, the resulting progression shown in Figure 21.2b constitutes a correct tonal progression.



FIGURE 21.2 Harmonic Flexibility of Counterpoint





JAZZ RULE OF THE OCTAVE




* * *



During the Baroque Era, the “Rule of the Octave” was a practical tool that enabled musicians to gain harmonic flexibility at the keyboard.5 The rule prescribed how to harmonize a scale in the bass using stylistic tonal progressions. In jazz, a similar rule can also be developed. Instead of placing the scale in the bass, the major scale is placed in the soprano voice. The jazz rule of the octave explains how to harmonize a descending major scale with idiomatic jazz progressions. By examining different harmonic outcomes, the relationship of melodies to chords and chords to melodies becomes clear. The jazz rule of the octave also helps us to realize the harmonic potential of different melodic segments and examines their behavior in the context of underlying chord progressions. Figures 21.3a–21.3d illustrate four distinct harmonizations of the descending major scale.



FIGURE 21.3A Jazz Rule of the Octave: Variant 1


Figure 21.3a features a diatonic realization of the scale. The tonic note is prolonged throughout the harmonization (dashed slurs) and only momentarily is left to create a harmonic contrast. As expected, the final harmonic gesture is in the form of a ii7–V7–Imaj7 progression.

Figure 21.3b illustrates a much bolder harmonization of the scale employing a root movement by fifths. Scale degrees and become reinterpreted as a ♭5th and ♭9th of ()/iii and ()/vi, respectively. It is worth noting that the initial tonic is absent from this harmonization. Known as an off-tonic progression, this and other off-tonic progressions are hallmarks of Phrase Models 2, 3, 5, and 13.6

Figure 21.3c illustrates how to infuse the scale with various tonicizations of closely related key areas. The notes of the descending scale become reinterpreted as different chord tones and extensions of supporting harmonies. For instance, the tonicization of IV capitalizes on reinterpreting as a major 9th of Gmin7 and a major 13th of C13 before resolving to Fmaj9 with in the soprano. Special attention should be paid to the behavior of inner voices as they continue to move by step and clearly delineate the structure of underlying chords.



FIGURE 21.3B Jazz Rule of the Octave: Variant 2




FIGURE 21.3C Jazz Rule of the Octave: Variant 3




FIGURE 21.3D Jazz Rule of the Octave: Variant 4


Unlike other harmonizations in the preceding figures, Figure 21.3d begins in the submediant key with a clear cadential confirmation of the submediant using the ()/vi progression. This particular off-tonic progression is especially common in the repertory of standard tunes. Before converging on the tonic, however, this harmonization also features tonicizations of IV and ♭III, and an elided motion to V with a II7 as harmonic support for . Even though this realization prioritizes the predominant collection of chords (as the confirmation of vi and tonicization of IV indicate) and modal mixture harmonies, these local key areas are ultimately related to the governing tonic. These eventually synchronize the melodic and harmonic forces at the end of the progression. In keeping with the notational practice employed in this book: parentheses are used to indicate the secondary ii7–V7s that resolve to their tonicized key areas; and square brackets to indicate secondary ii7–V7s that do not. For instance, the progression (ii7–V7)/IV in the key of C major indicates Gmin7-C7-FMaj7; the progression [ii7–V7]/IV stands for Gmin7-C7 followed by some other chord.





DIATONIC PHRASE MODELS




* * *



The concept of phrase models provides a general representation of harmonic progressions occurring in the repertory of standard tunes. Such prototypical progressions are fairly flexible and permit considerable harmonic and rhythmic variations with respect to the model’s phrase identifier, harmonic departure, and cadential confirmation. These components can, therefore, be (and frequently are) transformed without changing the original status of the model. These transformations or modifications usually relate to the harmonic properties of phrase models. In addition, they can also influence the overall duration and placement of individual components. Harmonic transformations typically involve various chord expansions, substitutions, and interpolations. Rhythmic modifications allow for different distributions of chords or harmonic progressions in relation to the underlying rhythmic and metric structure of the model. Such a degree of harmonic and rhythmic freedom allows for the classification of similar phrases within the rubric of a single phrase model.

Each diatonic phrase model is derived from a fundamental –– melodic pattern and appears in two distinct forms: (1) as a harmonic progression with essential chords analyzed only with Roman numerals, and (2) as a contrapuntal framework with guide-tone lines navigating through the supporting harmonies of the model. The use of analytical symbols is in keeping with a notational practice commonly used by music theorists: dashed slurs indicate the prolongation of essential tones or harmonies, beams shows phrase groupings, open note heads illustrate tones of greater structural significance than black note heads (these are further distinguished with either extended stems and/or flags), and scale degrees analyze notes of the tonic key. The discussion of each phrase model ends with five complete harmonic progressions and a partial list of standard tunes that share the harmonic characteristics of a particular phrase model.





Phrase Model 1


The overview of phrase models begins with the basic eight-bar progression. The use of a I–II–V progression as the phrase identifier is balanced with the use of a complete or incomplete II–V as the cadential confirmation. Notice that in Figure 21.4 (and in all the remaining figures showing the properties of phrase models) the structural chords of the model are notated with large-case Roman numerals. The phrase identifier (I–II–V) and the cadential confirmation (II–V) of Phrase Model 1 combine two tonal variants of the progressions: Imaj7–ii7–V7 or i7– and ii7–V7 or respectively. The middle part of Phrase Model 1 is reserved for the harmonic departure. This features a simple prolongation of the tonic or temporary tonicizations of closely or distantly related key areas. As stated earlier, these modifications do not alter the overall character of the model. Phrase Model 1 in Figure 21.4 features a relatively slow harmonic rhythm with one chord per measure. Frequently, however, the rate of harmonic rhythm is much faster, usually with two chords per measure.



FIGURE 21.4 Phrase Model 1


Figure 21.5 illustrates a contrapuntal framework of Phrase Model 1 and its derivation from a diatonic –– melodic pattern. Notice that in Figure 21.5 (and in all the remaining figures showing contrapuntal properties of phrase models) the chords are analyzed with complete Roman numerals. One of the advantages of such a representation (without bar lines and with essential harmonies only) is that it clearly shows the hierarchy between chords and contrapuntal forces generating the model. The exact distribution of chords and the type of harmonic departure are ultimately related to the characteristics of a specific standard tune.

The most salient feature of Phrase Model 1 is an on-tonic phrase identifier, which clearly projects the tonality of the tune. As a form-building entity, the cadential confirmation comes in two different types, complete and incomplete, and can be further classified as harmonically open, modulatory, and harmonically closed. A harmonically open pattern typically ends the first A section of the AABA- or the B section of the ABAC-type tunes. A modulatory cadential closure uses a ii7–V7 progression that prepares the arrival of a new key area in the B section of the AABA- or the B or C sections of the ABAC-type tunes. A harmonically closed cadential confirmation utilizes a ii7–V7–Imaj7 progression at the end of the tune.

Figure 21.6 illustrates some of the most interesting transformations of Phrase Model 1. These complete harmonic progressions are derived from the list of standard tunes below. Do you know which?

Phrase Model 1 can also accommodate a minor version of the phrase identifier (i.e. i7–) as in “You and the Night and the Music” or “Softly As In a Morning Sunrise.” But the contrapuntal framework of the model remains unchanged.



FIGURE 21.5 Phrase Model 1: Contrapuntal Framework




FIGURE 21.6 Phrase Model 1: Harmonic Variants


The list of songs that concludes the presentation of each phrase model contains a selection of familiar (and less-familiar) standard tunes that share the harmonic characteristics of a particular model. By studying these tunes, you can begin to notice the familiar traits and common characteristics between them.7 You can also observe how different harmonic transformations depart from the original phrase model and how they are generated. This and other lists are by no means exhaustive, but are an attempt to show the wealth of harmonic progressions in standard tunes sharing similar properties. One of the challenging aspects of this classification, however, is the proliferation of different versions of standard tunes in many fake books of questionable provenance. While such sources naturally present problems, they nonetheless offer an opportunity to take a fresh look at the repertory of standard tunes from the viewpoint of a practicing musician who has to frequently “improve” the existing lead sheet or sift through the surface chord progressions in order to understand the harmonic essence of a tune.





Phrase Model 2


The main characteristic of Phrase Model 2 is an off-tonic phrase identifier II–V, which can occur in the form of ii7–V7 or () progressions. Figures 21.7a–21.7c provide a basic harmonic layout of the model with an incomplete cadential confirmation, show a contrapuntal framework derived from a diatonic –– melodic pattern, and demonstrate common harmonic variants of the model.

Standard tunes that feature a progression at the outset are harmonically more advanced. The consequences of this modal borrowing are felt throughout the phrase such as in “I Love You,” where the harmonic departure ventures into the distant major mediant key area.





Phrase Model 3


Phrase Model 3 also features an off-tonic beginning and it vacillates around the predominant family of chords. Figures 21.8a–21.8c illustrate a basic harmonic layout of the model, show a contrapuntal framework derived from a diatonic –– melodic pattern, and provide common harmonic variants of the model that occur in the repertory of standard tunes.



FIGURE 21.8A Phrase Model 3




FIGURE 21.8B Phrase Model 3: Contrapuntal Framework


Phrase Model 3 accommodates different phrase identifiers, which, in turn, influence the overall content of the phrase. Despite their different surface manifestations, however, they can be derived from the fundamental IV–I motion. As you analyze the phrase structure of the following tunes, pay attention to the relationship between the melody and harmony, and how this interaction produces different harmonic outcomes.

Phrase Model 4


In a certain sense, the phrase identifier of Phrase Model 4, I–VI–II–V, constitutes a basic expansion of the phrase identifier of Phrase Model 1. One cannot help but notice, however, that the number of standard tunes with a clear manifestation of the I–VI–II–V progression is quite impressive. This progression is an important harmonic statement—fully integrated with the melodic structure—and therefore deserves a separate category. Figures 21.9a–21.9c demonstrate a basic harmonic layout of Phrase Model 4, show a contrapuntal framework derived from a diatonic –– melodic pattern, and provide common harmonic variations of the model.



FIGURE 21.9A Phrase Model 4




FIGURE 21.9B Phrase Model 4: Contrapuntal Framework


One of the characteristics of Phrase Model 4 is its flexible phrase identifier, which can occur in many different forms, as shown in Figure 21.9c. While some of these harmonic transformations are integrated in the context of standard tunes, such as “Love You Madly” or “Memories Of You,” others can be freely applied as effective harmonic substitutions.



FIGURE 21.9C Phrase Model 4: Harmonic Variants





Phrase Model 5


One of the salient features of Phrase Model 5 is a large-scale tonal motion from the submediant to the tonic. Standard tunes with this characteristic opening are often mistaken as being in the key of the opening chord. Figures 21.10a–21.10c illustrate a harmonic layout of Phrase Model 5, show a contrapuntal derivation of the model from a diatonic –– melodic pattern, and propose selected harmonic variants.

The harmonic variety of Phrase Model 5 is truly remarkable. The submediant chord can be cadentially confirmed as in “How Deep Is the Ocean?,” immediately departed from as in “I Hear a Rhapsody,” reached by arrival as in “The Shadow Of Your Smile,” or it can function as the initial chord of a longer sequential progression as in “Fly Me To the Moon.”

CHROMATIC PHRASE MODELS




* * *



One of the characteristic features of the remaining phrase models is their more intricate harmonic and contrapuntal design. Their phrase identifiers frequently employ tonicizing progressions and, as a consequence, harmonic departures are further removed from the tonic key. With more harmonic activities associated with the forthcoming phrase models, we can ask ourselves whether the different phrase identifiers are further elaborations of the fundamental diatonic frameworks or not. While this is definitely a possibility, the intention here is to show the more harmonic variety and salient characteristics of standard tunes.





Phrase Model 6


Phrase Model 6 has a characteristic phrase identifier that tonicizes the supertonic key area. This phrase identifier has tonicizing qualities and is frequently reinforced by the occurrence of specific notes in the melody. In the tunes “But Beautiful” or “Don’t Blame Me,” for example, ♭ is rendered as a ♭5th and ♭9th of the corresponding ()/ii progression. Figures 21.11a–21.11c provide a harmonic layout of Phrase Model 6, show a contrapuntal framework derived from a chromatic ––♯––– melodic pattern, and propose selected harmonic variants of the model. The melodic pattern of this model features an extended double neighbor figure with a chromatic pitch, ♯, functioning as the major 3rd of V7/ii.



FIGURE 21.11A Phrase Model 6




FIGURE 21.11B Phrase Model 6: Contrapuntal Framework




FIGURE 21.11C Phrase Model 6: Harmonic Variants





Phrase Model 7


The harmonic design of Phrase Model 7 constitutes an important jazz progression with a phrase identifier that tonicizes the submediant key area. This characteristic progression frequently implies the continuation of the sequence with subsequent tonicizations of key areas separated by thirds: I–VI–IV–II. Figures 21.12a–21.12c illustrate a harmonic layout of Phrase Model 7, show a contrapuntal framework derived from a diatonic –––– melodic pattern, and propose different harmonic realizations of the model.

Phrase Model 7 is related to the cycle of the dominant 7ths progression: III7–VI7–II7–V7. In the context of standard tunes, the submediant chord can function as a tonicized key area as in “Come Rain Or Come Shine,” or as a passing harmony as in “There Will Never Be Another You.”

Phrase Model 8


Phrase Model 8 is a prototype for the important subset of harmonic progressions frequently found in the repertory of standard tunes. The phrase identifier features a motion from I to IV. Since this fundamental harmonic motion has strong blues implications, the subdominant harmony often takes the form of a dominant 7th as in “Willow Weep For Me” or “Tenderly.” Figures 21.13a–21.13c illustrate a harmonic layout of Phrase Model 8, show a contrapuntal framework derived from a diatonic –– melodic pattern, and suggest different harmonic variants of the model.





Phrase Model 9


Phrase Model 9 features a chromatic phrase identifier that pulls the phrase into the flat submediant key area. Figures 21.14a–21.14c illustrate a harmonic layout of Phrase Model 9, show a contrapuntal framework originating from a chromatic –♭––– melodic pattern, and recommend harmonic variants of the model. Scale degree flat two is reinterpreted as the minor 3rd and minor 7th of a (ii7–V7)/♭VI progression. The resolution to over the ♭VI harmony fulfills the rules of counterpoint.

The selection of songs featuring this particular phrase identifier is rather small. In the case of “What’s New” and “Here’s That Rainy Day,” the phrase identifier and the ♭VI key area are clearly articulated. “You Stepped Out Of a Dream,” however, presents a more ambiguous case because the intervening ♭IImaj7 harmony in the opening phrase expands the tonic before the (ii7–V7)/♭VI progression occurs.

Phrase Model 10


Phrase Model 10 features a chromatic phrase identifier tonicizing the flat supertonic key area. More often than not, however, a [ii7–V7]/♭II progression occurs in an incomplete form without resolving to ♭II. Figures 21.15a–21.15c illustrate a harmonic layout of Phrase Model 10, show a contrapuntal framework derived from a chromatic –♭––– melodic pattern, and propose harmonic variants of the model. In Phrase Model 10, ♭ functions as a minor 7th of the underlying ii7/♭II harmony. The resolution to over V7/♭II satisfies the rules of voice leading.

What is interesting about the [ii7–V7]/♭II progression is that it frequently functions as an effective harmonic substitution provided that the melody note establishes a convincing chord–scale relationship with the underlying harmony. After all, it is situated a minor 2nd away from the structural ii7–V7 progression and, as discussed in Chapter 6, the [ii7–V7]/♭II often functions as a chromatic sidestepping progression. In the context of “Darn That Dream” or “Out Of Nowhere,” however, the [ii7–V7]/♭II is fully integrated within the harmonic structure of these tunes. In “The Lady Is a Tramp” and “I Guess I’ll Hang My Tears Out To Dry” only the [ii7]/♭II is employed as a chromatic elaboration of the otherwise diatonic opening.

FIGURE 21.15C Phrase Model 10: Harmonic Variants





Phrase Model 11


Phrase Model 11 features a descending major 2nd cycle beginning on the tonic and—following the subsequent tonicizations of ♭VII and ♭VI—ending on ♭VI. Even though there is only a handful of tunes that use this progression in its entirety, an incomplete Phrase Model 11 (with a partial descending major 2nd cycle) can occur in the context of different harmonic progressions. Figures 21.16a–21.16c show a chord structure of Phrase Model 11, illustrate a contrapuntal derivation from a –– melodic pattern, and offer possible harmonic variations.

The most famous occurrence of Phrase Model 11 is found in “How High the Moon.” Apparently, this harmonic sequence was very appealing to a host of musicians from the 1940s and beyond, as they often used this challenging chord progression to test their improvisational prowess. Other tunes from the list, such as “Star Eyes” or “Twilight World,” cleverly manipulate the model. “Midnight Sun,” meanwhile, features a highly chromatic melody to reinforce the sequential nature of the chord progression.

Phrase Model 12


Phrase Model 12 has a characteristic phrase identifier that features a ♯IV harmony. As explained in Chapter 4, this particular harmony supports and can participate in two common harmonic scenarios: as a half-diminished chord or as a min7(♭5). The former often initiates a descending chord progression, ♯ivø7–iv7–iii7–♭iiio7–ii7–V7–Imaj7, which is typically associated with the tag-ending progression. The latter functions in the context of a ()/iii progression tonicizing the mediant key area. Figures 21.17a–21.17c show a basic harmonic structure of Phrase Model 12, illustrate a contrapuntal derivation from a –– melodic pattern, and demonstrate harmonic variants of the model.



FIGURE 21.17A Phrase Model 12




FIGURE 21.17B Phrase Model 12: Contrapuntal Framework




FIGURE 21.17C Phrase Model 12: Harmonic Variants


When you examine the list of tunes that share Phrase Model 12, you can see how crucial the chord–scale relationships are between the melody and the phrase identifier. In “I Remember You” or “Whispering,” the /iii harmony supports , which locally functions as an 11th of the underlying chord. “Stella By Starlight” or Miles Davis’s version of “I Thought About You” do not begin with the opening tonic; this suggests the possibility of an off-tonic version of the model as well.9 One interesting aspect of the progression is its potential for reharmonization. The phrase identifier of this model (either with or without the opening tonic) can be employed as a substitute progression for Phrase Model 2, provided that the structure of the melody permits for such a substitution. The design of the melody, then, is the ultimate factor allowing the implementation of this substitution. For instance, the A section of “Over the Rainbow” can be reharmonized with the phrase identifier of Phrase Model 12. Also, the A sections of “I Should Care” or “Our Love Is Here To Stay,” which share Phrase Model 2, can also be realized with Phrase Model 12.

Phrase Model 13


Phrase Model 13 concludes the inventory of phrase models in standard tunes. In contrast to other phrase models, this model constitutes a harmonic sequence of dominant 7th chords and is largely associated with the harmonic structure of the bridge in “I Got Rhythm” and its countless contrafacts. Figures 21.18a–21.18c illustrate a basic harmonic framework of Phrase Model 13, show a contrapuntal derivation from a – melodic pattern, and offer harmonic variants of the model.

In its incomplete form (i.e. without the opening III7), Phrase Model 13 occurs in a number of tunes, such as “A Good Man is Hard To Find,” “Lazy River,” “Alabama Jubilee,” “Miss Brown To You,” “Old Man Moon,” or “Sweet Georgia Brown.”

NOTES



* * *



1. The term “standard” refers primarily to American popular tunes performed frequently by countless musicians working from ca. 1920–1960.

2. Even though this discussion is focused on eight-bar phrase models, the same properties can be used to explain the structure of 16-bar phrases that occur in extended forms and/or more complicated tunes.

3. Melodic patterns are reductions of actual melodies to their structural pitch content.

4. One of the explanations for the primacy of fifth-root movement is related to the occurrence of the perfect 5th in the overtone series between the low-integer ratios 2:3.

5. François Campion in Traité d’accompagnement et de composition, selon la règle des octaves, translated by L. Dragnone as “François Campion’s Treatise on Accompaniment: A Translation and Commentary,” offers harmonization of both major and minor scales.

6. In his description of prolongation, Henry Martin in “Jazz Harmony: A Syntactic Background” claims that “many popular jazz songs project a key by arrival rather than by simple prolongation of a single tonality designated early on.” The terms “on-tonic” and “off-tonic” employed in this book are modeled on Martin’s pioneering explanation of the tonality of popular tunes.

7. The songs written in bold indicate standard tunes that constitute the core of jazz repertory.

CHAPTER TWENTY-TWO


The AABA Song Form





CHAPTER SUMMARY



* * *



Chapter 22 undertakes a study of song forms and its most common type: the 32-bar AABA. Two tonal variants, on-tonic and off-tonic, are examined and, as an example of the on-tonic AABA formal design, “Have You Met Miss Jones?” is analyzed.

FORMAL PROTOTYPES




* * *



The term “standard” is often used to denote tunes that comprise the core repertory of jazz. The term is an interesting one because it implies that a particular object satisfies certain accepted constraints or that its representation has become, to a certain degree, institutionalized. Tunes that jazz musicians consider standards were largely composed by American songwriters active in the first half of the twentieth century, many of whom have become household names in jazz history: Irving Berlin, George Gershwin, Cole Porter, Victor Young, Richard Rodgers, Jerome Kern, Harold Arlen, Jimmy Van Heusen, Frank Loesser, Howard Dietz, Jule Styne, Hoagy Carmichael, and many others. These prolific composers often collaborated with equally remarkable lyricists (Ira Gershwin, Lorenz Hart, Oscar Hammerstein, E.Y. “Yip” Harburg, Dorothy Fields, Johnny Mercer, Sammy Cahn, Ted Koehler) and together they produced hundreds of excellent songs that eventually made their way into the jazz repertory.

The 32-bar AABA form is the most common formal prototype underlying the repertory of standard tunes. In the overview of this formal model, we will distinguish between two distinct tonal variants: on-tonic and off-tonic. These variants are ultimately related to the type of phrase models that occur at the beginning of a tune. In Chapter 21, Phrase Models 2, 3, 5, and 13 featured an off-tonic phrase identifier, while the remaining models began on the tonic chord. Whereas phrase models capture the harmonic characteristics of common eight-bar phrases that occur in the A, B, and C sections of the tune, the formal prototypes combine phrase models in their most basic harmonic setting and illustrate possible tonal departures in the bridge (or other sections). Depending on the complexity of the tune, the prototype may include anywhere from one to four phrase models. “Can’t We Talk It Over,” for instance, features only one phrase model; whereas “Stella By Starlight” combines four distinct phrase models, one for each eight-bar phrase in the song. By and large, the formal prototype with two unique phrase models (albeit with some melodic and harmonic variations) is by far the most common.

Broadly speaking, the phrase structure of the tunes in AABA consists of four eight-bar sections and uses a single phrase model for the A sections and a different phrase model for the B section. The phrase model for the B section is usually accompanied by the harmonic motion to a new key area. Each of the eight-bar sections is typically divided into two four-bar phrases. This regular phrase subdivision is emphasized by the fairly regular distribution of chords and harmonic progressions. In certain tunes, such as “I’m Getting Sentimental Over You” or “The Nearness Of You,” a four-bar phrase extension expands the final A section. The melody of standard tunes is always accompanied by the lyrics. The lyrics frequently reinforce salient features of the melody and highlight important harmonic events. They can even disguise the symmetry of eight-bar phrases by placing textual cadences at locations different from those supplied by the musical meter.

In the process of learning new tunes, it is useful to find the earliest vocal version of the tune that you intend to learn. Even though early vocal performances might not be in keeping with jazz performance practice, they are helpful in authenticating the song’s mood, tempo, phrasing, and even some of its harmonic intricacies. It is more valuable to learn a tune from the original recording since later recorded versions might represent transformed versions of the song’s harmony, melody or rhythm. Listen to the words and how the singer phrases the words. Learn the lyrics. Keep them in mind when you decide how you want to phrase the song. Finding the original sheet music of the tune that you want to learn may also be beneficial. The harmonic and melodic information included in the original sheet music is often different from fake-book lead sheets. Not only does the original contain the correct melody, harmony (realized as the piano accompaniment), and lyrics as intended by the composer, but it also includes the verse that is often omitted from the fake-book version. You may be surprised to discover how different composers use the verse to foreshadow the overall mood of the song or highlight some salient features that later resurface in the chorus. This information can in turn influence your rendition of the song.





THE AABA ON-TONIC DESIGN




* * *



The AABA on-tonic design usually features two phrase models: one for the A sections; the other for the B section, also known as the bridge or release. The tonic chord is clearly announced at the outset of a tune. The first A section is harmonically open and typically ends with a ii7-V7 progression in m. 8. The second A section is tonally closed and, following the cadential confirmation of the main key, ushers in a new phrase model. The bridge introduces contrasting melodic and harmonic material that balances the overall distribution of phrase models. The end of the bridge includes an important formal event, an interruption: this event signals the conclusion of the first part of the tune and marks the return of the main key.1 The harmonic interruption might also overlap with a more substantial harmonic departure occurring in the bridge. For instance, the B section of “I’ve Never Been In Love Before” begins on IV and features a harmonic departure on III, before the reinstatement of the tonic with a ii7-V7 progression in m. 24.

Figure 22.1 illustrates a generic distribution of phrase models in the AABA on-tonic formal prototype.

The harmonic design of the B section is a defining feature of the song and enables the classification of standard tunes according to their shared tonal and harmonic characteristics. There are a few different scenarios that may happen at the beginning of the bridge. In the most basic scenario, a new chord—still within the orbit of the main tonality—initiates a different (from the A section) chord progression. This new chord can be further reinforced with a local ii7-V7 progression occurring at the end of the second A section. For instance, the bridge sections of “There’s a Small Hotel” or “Imagination” begin on IV. However, these subdominant chords do not function as new key areas; in neither case are they confirmed by a cadence or reinforced as a local tonic. In the second, more intricate scenario, the new key area of the bridge is tonicized at the end of the second A or reached by arrival at some point during the bridge. For instance, in “Mean To Me” the subdominant key area is clearly tonicized in m. 16 and subsequently prolonged during the first part of the bridge. In “I Can’t Get Started” the arrival on to the supertonic key area is reached by arrival in m. 19 following a tonicized ii7-V7 progression in mm. 17–18. In addition, there are also tunes with tonally ambiguous bridges that cannot be easily classified. Even though the bridge of “Don’t Blame Me,” for instance, starts on the subdominant, this chord inevitably leads to the hierarchically more important submediant harmony two measures later.

Classification of Standard Tunes2


Below is a list of standard tunes cast in the AABA on-tonic form that share similar harmonic traits at the outset of the bridge. Unlike Chapter 21, however, where standard tunes were classified according to the harmonic similarities occurring at the phrase level, this list is organized according to the tonal characteristics at the formal level. Standard tunes with direct or indirect harmonic motion to the subdominant are by far the most common. An “*” indicates tunes where the key area (or hierarchically more important chord) at the beginning of the bridge is reached by arrival.

THE AABA OFF-TONIC DESIGN




* * *



In addition to the on-tonic model, the AABA off-tonic design is an important formal prototype in standard tunes. The main characteristic of the off-tonic design is the absence of the tonic at the beginning of the tune. Since Phrase Models 2, 3, 5, (12), or 13 have phrase identifiers that do not start on the tonic chord, tunes sharing this type of design are likely to employ these phrase models for the A sections. Figure 22.2 demonstrates a generic distribution of phrase models in the AABA formal prototype.

“HAVE YOU MET MISS JONES?”—AN ANALYSIS




* * *



Figure 22.3 gives the original sheet music for the tune “Have You Met Miss Jones?” by Richard Rodgers and Lorenz Hart.4 This song is an example of the 32-bar AABA on-tonic form. The top stave includes the chord changes from a published lead-sheet version. Since the chord changes differ from the piano accompaniment, both will be used in the following analysis. Figure 22.3 also includes the verse, which in the hands of great songwriters has interesting features that later resurface in the chorus.





The Verse


After a four-measure introduction, the verse of “Have You Met Miss Jones?” is 12 bars long and, like a typical blues, contains three symmetrical four-bar phrases. The first two phrases (mm. 1–8) are variants of one another. The third phrase (mm. 9–12) features a descending octave (overshot by an upper chromatic neighbor, D♭5) from C5 to C4, and uses the basic melodic gestures from the opening phrase. The first phrase is harmonically open and ends with a ii7-V7 progression in the tonic key. The second phrase (mm. 5–8) is tonally closed, but a tonicization of the subdominant in m. 8 with the resolution in m. 9, creates a sense of harmonic momentum. After the subdominant departure, the phrase proceeds to a half cadence in m. 12 using a modified cycle of fifth progression.

The melody of the verse establishes an interesting chord-scale relationship. The sense of eagerness that emanates from the narrator’s murky recollections is captured melodically by the blues inflection of 3̂ and the occurrence of an unprepared major 9th in mm. 1, 5, and 9. The harmonic support for these two pitches is quite adventurous when consulting the piano accompaniment. The A♭4 in m. 1 in the lead-sheet version receives a harmonic support from the A♭°7 chord. The piano accompaniment uses the same chord but over the C pedal, which offers a much more interesting harmonic realization. In m. 2, the G4 on beat 4 receives the same pedal point support and the underlying A♭° renders the melodic pitch as the major 7th. With the lyrics: “And now, you see, we mustn’t wait” in m. 8, the melody frees itself from a downward slump and ascends to 5̂, which is harmonically reinforced with a tonicization of the subdominant. A motivic descent to 5̂ in m. 12 effectively summarizes the overall arch-like architecture unfolding in the verse.





The Chorus


In order to make our musical analysis pertinent to improvisation, it is necessary to know what attributes make “Have You Met Miss Jones?” stand out from other standards built from similar chord progressions. In other words, the analysis should gather the most relevant information about the tune’s properties that can later be explored in improvisation. Four broad characteristics—formal, tonal, melodic, and harmonic—can be used to describe salient characteristics of the tune. It is not sufficient, however, to consider these categories as separate entities, but to examine them in relation to one another. The analytical method advocated here asks the following question: What is it that makes “Have You Met Miss Jones?” (or any other tune) unique and distinguishes it from other tunes with similar tonal and formal properties? Finding an answer will lead to a more successful improvisation and better understanding of the tune’s properties.





FIGURE 22.3 Original Sheet Music—“Have You Met Miss Jones?“


Formal Characteristics

The form of “Have You Met Miss Jones?” uses a 32-bar AABA on-tonic design with harmonic motion to the subdominant at the outset of the B section. As is the case with most standard tunes, the A sections are symmetrical with clear four-bar phrase subdivisions. The B section is more sophisticated and features a 2+2+4 phrase division similar to so-called sentence structure.5

Tonal Characteristics

The phrase structure of the tune uses Phrase Model 4 for the A section and Phrase Model 3 for the B Section. The harmonic rhythm in the A section is relatively slow with one chord per measure. Phrase Model 4 occurs in the most basic form without any unusual harmonic activities in the midst of the phrase. The first A section is tonally open and ends with a structural ii7-V7 supporting 4̂. The second A section confirms the tonic and subsequently tonicizes the subdominant emerging at the beginning of the bridge. The chord structure of the bridge is classified as Phrase Model 3 because of its relationship to the main key and large-scale tonal organization of the song as a whole. The bridge begins on IV, which is tonicized in mm. 15–16, but neither cadentially confirmed nor harmonically prolonged. Even though a chromatic sequence in mm. 18–23 touches on distant key areas and ultimately ends on HI in m. 23, a ii7-V7 in m. 24 prepares the reinstatement of the tonic key. Thus the chord structure of the bridge begins on IV—which is then followed by a complex harmonic departure—and ends with an incomplete cadential confirmation of I, just as in Phrase Model 3. The final A section includes a stepwise ascent to the climactic E5, which gives the word “die” a new meaning and closes with a complete cadential confirmation of the tonic. The intricate harmonic sequence that occurs in the bridge is the most important tonal event of the song. The subdominant in m. 17 initiates a sequential progression that combines two intervallic cycles: major 2nd and major 3rd. At a macro level, each tonicized key area—IV, ♭II, and VI—creates a major 3rd cycle that projects the roots of a B♭ augmented triad. At a micro level, the progression descends by major 2nds and intersects with the major 3rd cycle.

Melodic Characteristics

The melodic structure of the tune uses the composer’s signature trademarks: stepwise melodic motion, motivic parallelism, measured use of skips, melodic rests on harmonically active pitches, and a compound melody. In comparison to the verse, the relationship between the melody and harmony in the A sections is not as daring, and largely depends on the use of chord tones on strong beats and passing/neighbor notes on weak beats. The bridge, on the contrary, creates more melodic tension by highlighting accented 9ths in mm. 17, 19, and 21 (in relation to the corresponding local major chords), which initiate sequential melodic repetitions.

Harmonic Characteristics

The longest note of the tune (B♭4 in mm. 7–8) has interesting harmonic implications. Because of the harmonic support it receives from a diatonic ii7-V7 progression and (potentially) from a chromatic [ii7-V7]/♭II, 4̂ can participate in both environments. In improvisation, we can effectively capitalize on the note’s dual harmonic membership. The projection of the augmented triad in the bridge suggests the use of more adventurous melodic and harmonic vocabulary that could infiltrate our improvisation.

Summary of Features

What is it that makes “Have You Met Miss Jones?” unique? We can answer this question as follows:

1. Formal considerations—the symmetrical phrase structure of the chorus parallels the symmetrical structure of melodic lines.

2.Tonal considerations—since the B section is more adventurous and provides harmonic relief from the diatonic A section, the solo can explore the contrast between diatonic and chromatic elements.

3.Melodic considerations—the blues inflections of the verse and the stepwise melodic design of the chorus imply that melodic lines can have similar characteristics.

4.Harmonic considerations—since the phrase identifier of Phrase Model 4 can be transformed harmonically and the longest note of the tune (B♭4 in mm. 7–8) can be harmonized using ii7-V7 or [ii7-V7]/♭II progressions, the solo can capitalize on these harmonic devices.

THE ABAC ON-TONIC DESIGN




* * *



The 32-bar ABAC on-tonic design (similar to the AABA) is an example of the binary interrupted form. The harmonic interruption occurs in m. 16 and divides the form into two large tonal motions: I–V in mm. 1–16 and I–I in mm. 17–32. Because of the absence of a clearly articulated bridge, which is the defining feature of the AABA tunes, the ABAC form is more ambiguous and thus less codifiable. Tunes in the ABAC form have a different phrase distribution and are usually characterized by more complicated melodic, harmonic, and rhythmic designs. Even though the designations “B” and “C” imply the use of different phrase models, in practice these sections are frequently related to one another. Figure 23.1 illustrates a generic distribution of phrase models for the ABAC on-tonic design.

This formal structure suggests two different distributions of phrase models. In the first one, each eight-bar section is analyzed with a unique phrase model just as in “Blame It On My Youth” or “The Touch Of Your Lips,” which feature a faster harmonic rhythm and more intricate melodic design. In tunes such as “Get Out Of Town” or “I Could Write a Book,” however, with a slower harmonic rhythm and uninterrupted melodic flow spanning mm. 1–16 and mm. 17–32, only a single phrase model suffices to explain the harmonic properties of both sections.1

“ALL OF YOU”—AN ANALYSIS




* * *



Figure 23.3 illustrates the original sheet music of Cole Porter’s “All Of You.”4 This song is an example of the 32-bar ABAC off-tonic form. The top stave includes the chord changes from a published lead-sheet version. Since the chord changes differ from the piano accompaniment, both will be used in the following analysis.





The Verse


The verse sets the overall character of the song and foreshadows certain events that become more apparent in the chorus. For instance, a two-note melodic anacrusis in the verse becomes a three-note gesture in the chorus; an off-tonic beginning on B♭7/F in the verse is mirrored by an off-tonic beginning on A♭, A♭min6, or Fmin7(♭5) in the chorus, depending on the version. Each four-bar phrase in the verse has basically the same melodic architecture with a balanced contour and the prevalent use of stepwise motion. The melody establishes a strong chord–scale relationship with the chord tones aligned with beats 1 and 3, and passing notes placed on beats 2 and 4. This lack of melodic/harmonic tensions suddenly becomes disrupted in the chorus where the chromatic chord–scale relationships prevail and larger intervallic leaps dominate the melody. The verse concludes with the words “And it’s not a passing fancy or a fancy pass,” with a perfectly balanced melody supported by an expanded ii7–V7 progression. In the original piano accompaniment, Porter elaborates the dominant 7th in m. 15 with a common-tone diminished 7th chord, E°7, which is an idiomatic harmonic device typical of the blues.





The Chorus


In the forthcoming analysis, we will concentrate on tonal, melodic, harmonic, and metric/rhythmic characteristics of the tune and discuss ways in which they influence the overall approach to improvisation. The chorus has a relatively uniform tonal architecture: the first A section uses Phrase Model 3 with an open cadence on V7 in m. 8, while the B section employs Phrase Model 1 with a modified phrase identifier (notice the interpolation of ♭iiio7 in m. 10) and an open cadence on V7 in m. 16. The second A section differs from the first A, particularly in mm. 21–24. At the end of this section, an elided [ii7−V7]/ii anticipates the arrival of the C section. Rather than resolving the [ii7−V7]/ii to the expected minor supertonic, Porter thwarts our expectations and shifts the music to IVmaj7 in m. 25. The C section utilizes Phrase Model 3 with a tonicization of ii in m. 26. Notice that this harmonic departure is initiated by chromatic sidestepping ()/iii that triggers a sequence of ii7–V7s in mm. 27–30 and brings the tune to an end.

The lyrics also contain some important textual associations that enrich our understanding of the song. Each time Porter uses the word “you” in the A section, he accompanies it by a metric, durational, and melodic stress. Its rhymed counterparts–“lure” and “tour”— support ♭, giving the melody a characteristic poignancy. This note also triggers the largest and most audacious intervallic leap of a major 7th in m. 7 over the predominant . This chord sounds particularly expressive and its unique quality stimulates the choice of chordal extensions for the V7 in m. 8.





FIGURE 23.3 Original Sheet Music—“All Of You”


The tonal architecture of “All Of You” features unique harmonic progressions. In mm. 1–2, the succession of iv6–Imaj6 establishes the overall character of the song. This progression, along with its variant —Imaj7, is by far the most common harmonic choice used by jazz musicians. However, it is clear from the original sheet music that Porter had a different harmonic idea for mm. 1–2: his realization features an A♭ major (!) chord over the tonic pedal B♭. Only with the arrival of C♭3 in m. 3 does he change to an A♭ minor chord. The minor subdominant in m. 3 borrows ♭ from the parallel minor key, and is known as a mixture chord.5 This and other modal borrowings (e.g. ♭ in m. 14) greatly enhance the character of the melody and influence the choice of other harmonies: C7(♭9) in m. 14 and Fmin7(♭5) in mm. 3, 7, and 19. With the occurrence of the tonic in m. 2, the A section becomes tonally ambiguous and in search of the tonal stability. Porter makes this search a compelling journey with various harmonic detours (mm. 7–8 and 25–26), deceptive resolutions (mm. 8–9 and 23–25), and modal mixture chords (mm. 3, 7, 14, 17, 19, and 21). When he finally confirms the tonic in mm. 29–32, Porter pulls out all the stops: he accentuates each word of the final phrase—“For I love all of you”—with half-note values and harmonizes the entire four-bar closing section with a diatonic ii7–V7–Imaj7 progression. In the piano accompaniment, the bass voice counterpoints the soprano with a ascent with each bass note supporting different chords: Fmin–C7/G–A♭6–B♭9, respectively. With such a robust and convincing ending, Porter resolves all previously accumulated melodic and harmonic ambiguities.

The B section of “All Of You” uses a harmonically open Phrase Model 1 that interrupts the form in m. 16. In some versions of the song a different harmony in m. 9 may be encountered. The use of functionally equivalent mediant harmony in place of the tonic, however, is within the limits of acceptable harmonic substitutions. The occurrence of ♭iiio7 in m. 10 is a particularly important harmonic event in the B section. This diminished 7th passing chord occupies the whole measure, improves the overall voice leading, and provides a convincing harmonic support for the melody. In addition, it also establishes a chord–scale relationship with a 2/1 octatonic I.

A harmonic shift to the subdominant at the beginning of the C section is in keeping with the tonality of numerous jazz songs where a similar harmonic progression signals the closing section. The harmonic supports for D5 in mm. 25–26 constitute yet another salient feature of “All Of You.” The D5 is harmonized with A♭Maj7 in m. 25 and with Amin7(♭5)–D7(♭9) in m. 26. These harmonizations suggest specific chord–scale relationships: Lydian in m. 25 and 2/1 octatonic I in m. 26.

Summary of Features

The following points suggest one of many possible directions that can be taken during improvisation on “All Of You”:

1. Tonal considerations—since the tune plays on tonal expectations, the idea of tonal ambiguity can be explored. One that stems from the analysis suggests the use of mixture chords and functionally equivalent harmonic substitutions.



2. Melodic considerations—since the melody employs considerable intervallic leaps, melodic lines can have a more angular contour with larger intervallic leaps.



3. Harmonic considerations—since the diminished 7th chord in m. 10 and the IVmaj7/iii progression in mm. 25–26 feature attractive chord–scale relationships, they can be explored during improvisation.



4. Metric/rhythmic considerations—the melodic anacrusis in the verse and the chorus suggests a particular design that seems to foreshadow the upcoming harmony rather than retroactively respond to it. This proactive approach to phrasing and harmony creates better melodic flow and can ultimately influence the overall rhythmic architecture of the solo.

Extended and Unusual Song Forms





CHAPTER SUMMARY

Chapter 24 provides a list of standard tunes with extended and unusual formal designs. As an example of the extended form, “Dream Dancing” is analyzed.





CONCEPTS AND TERMS

• “Night and Day” duality





EXTENDED AND UNUSUAL SONG FORMS—A COMPILATIOND1




* * *



In addition to the 32-bar AABA and ABAC forms, there are other, less common formal designs with unusual tonal characteristics, different phrase distributions, and extended structures. Standard tunes with unusual formal designs might present a challenge to the improviser because they typically unfold in a less regular manner and feature more intricate harmonic progressions. For each song listed in Figure 24.1, the length of individual sections is indicated in measures and the length of the form provided.





“DREAM DANCING”—AN ANALYSIS




* * *



Among the numerous songs featuring extended formal designs, “Dream Dancing” by Cole Porter is one of the most interesting.2 Figure 24.2 illustrates a lead sheet version of “Dream Dancing” including the verse.





FIFURE 24.1 Extended and Unsual Standard Songs





FIFURE 24.2 Lead Sheet—“Dream Dancing”





The Verse


The verse is 16 bars long and has recitative-like qualities.3 For instance, mm. 1–4 introduce a tonic pedal commonly used in recitatives. The melody has a static design, features a syllabic declamation of the words, and receives harmonic support foreshadowing salient characteristics that will become manifested in the chorus. The overall tonal architecture of the verse implies a large motion T-PD-D with the tonic occupying mm. 1–8, the predominant mm. 9–14, and the dominant mm. 15–16. These functional areas feature some interesting harmonic parallelisms. For instance, the progression from mm. 5–7 reappears in a transposed and enlarged version in mm. 9–12. The most striking harmonic event occurs in mm. 13–14 where the lyrics, “to live again,” receive a [ii7–V7]/II harmonic support.





The Chorus


The phrase structure of “Dream Dancing” does not conform to any traditional formal models: the distribution of phrases, the placement of structural cadences, and the unfolding of lyrics suggest a three-part form. Figure 24.3 illustrates a formal diagram of the tune.



FIFURE 24.3 “Dream Dancing”—Formal Diagram


Formal Considerations

The A section is 16 bars long and combines two eight-bar phrases that loosely follow the harmonic structure of an incomplete Phrase Model 5 for mm. 1–8 and Phrase Model 3 for mm. 9–16. The B section in mm. 25–32 is eight bars long and resembles Phrase Model 3 with its characteristic off-tonic phrase identifier on IV. The final C section in mm. 41–52 is 12 bars long and features a four-bar interpolation of an elided [ii7–V7]/II progression from mm. 13–14 of the verse. “Dream Dancing,” then, is a composite 52-bar form unlike any existing formal prototype.

Harmonic Considerations

One particularly unusual characteristic of the tune is the harmonic progression in mm. 1–4 and 17–20. The occurrence of the tonally ambivalent major submediant coupled with a chromatic alteration of —if heard in the opening progression in the context of C major—is far removed from the main tonic. This opening resembles Phrase Model 5 with its offtonic phrase identifier in the submediant. However, unlike other tunes that share this model, “Dream Dancing” begins on V7/VI, which tonicizes a local tonic on VI. Given the nature of the opening progression and the subsequent tonicization of IV in m. 8, the tonality of the tune is evasive and neither prolonged nor confirmed.

The tonicization of IV in m. 8 installs an off-tonic Phrase Model 3 that features an important harmonic event: a [ii7–V7]/II progression in m. 13. Porter uses this salient progression to announce the word “dream.” The other title word, “dancing,” receives harmonic support from a ii7–V7 progression. A more forceful confirmation of the tonic occurs in mm. 14–15, but the subsequent tonicization in m. 16, [ii7–V7]/IV, thwarts the tonal expectations and does not resolve to the expected subdominant but to V7/VI in m. 17. The chord succession in mm. 16–17 also features two dominant 7th chords a major third apart; in addition to the chromatic progression from m. 13, these sonorities constitute the most important tonal characteristics of the song.

The second part of the tune begins in m. 33 with the lyrics “Dream dancing.” Measures 33–40 resemble Phrase Model 3 with an off-tonic phrase identifier on IV. The tonality of the song is climactically declared in m. 40 and marks the beginning of the final section of the tune. The arrival of the tonic in m. 41 emphasizes the structural downbeat, features the important word “love,” and employs Phrase Model 8, the only on-tonic phrase model of the entire song. Measures 45–49 interpolate the [ii7–V7]/II progression three times in quick succession and, with the lyrics “Dream dancing, To Paradise prancing, Dream dancing with you,” lead to the final cadence in the tonic, an emphatic end to this fascinating harmonic journey.

Melodic Considerations

The melodic design of “Dream Dancing” is equally interesting. Each time the title words appear in the lyrics they are accompanied by a characteristic melodic gesture. In mm. 13–14, for instance, the motto of the song features a minor third from to . In mm. 33–34, the same words project a downward octave leap from to . Finally in mm. 49–50, “dream dancing” highlights a minor third skip from to . Notice that in mm. 13 and 45 the minor third skip begins on : these chromatic pitches allow Porter to inject a subtle blues flavor into the structure of the song.

A chromatic inflection of in mm. 1–4 constitutes an unusual melodic feature of the tune. While in other standard tunes the tonic note is typically left untouched (especially at the outset of a song), in “Dream Dancing” the rhetorical interplay between and reflects the nature of the lyrics: “When day is gone and night comes on.” The lyrics depict the familiar “Night and Day” duality—one of Porter’s favorite conceits and something that he highlighted through his choice of melodic notes and harmonic progressions.4

Summary of Features

Improvising on a tune like “Dream Dancing” can be an arduous undertaking. Among the numerous challenges, the convincing articulation of the formal structure, correct assessment of the harmonic function of distantly related chords, and the use of chromaticism should be at the center of consideration. The following points offer a summary of features to be explored during improvisation:

1. Formal considerations—based on the analysis of the tune, we can see ways in which the composer plays with tonal expectations and postpones the arrival of the tonic until m. 41. This gradual and measured emergence of tonality suggests that the solo can have similar properties, especially in the way the local progressions and the climax of the solo are articulated.

2. Melodic considerations—since the melody features some unusual chromatic inflections, the use of bold chromaticism can be a part of the solo.

3. Harmonic considerations—the prominent role of [ii7–V7]/II and the dominant 7ths a major third apart suggest the use of these progressions during improvisation with a fitting selection of chord–scale relationships.

4. Tempo considerations—with extended formal structures, we can experiment with different tempi and/or time feels. In addition to a swing feel, “Dream Dancing” lends itself to a straight 8th-note feel (as performed on the Play Along DVD).

INTRODUCTION




* * *



The terms “harmonization” and “reharmonization” are somewhat related to one another as they describe the process of “fleshing out” chord progressions with fully or partially realized harmonic structures. Harmonization involves supporting a tune with a suitable chord progression. Reharmonization then takes that progression and modifies it in a considerable way. While these newly created harmonic modifications might be quite substantial, they are usually traceable to and motivated by the original chord changes. The term “reharmonization” employed in this chapter refers to both processes: realization and harmonic reworking. The process of reharmonization, then, uses both the original and any modified chord progressions to render fully or partially realized harmonic formations. One of the goals of reharmonization is to provide a set of new chord changes that support the melody of a song. The melody, then, is the ultimate source for all harmonic choices.

Historically, harmonic explorations of the melody have been tied to the art of composition and improvisation. By studying different genres of composition that primarily focus on harmonic and contrapuntal reworkings of the melody, such as passamezzos, folias, passacaglias, chaconnes, fantasias, chorale preludes, suites, and the theme and variations, you discover that the practice of reharmonization has indeed a long and rich tradition.1 Let’s examine how J.S. Bach explored the potential of the chorale melody “Herzlich tut mich verlangen.” Figure 25.1 compares three (out of nine) harmonic reworkings of the Passion chorale.2





FIGURE 25.1 “Herzlich tut mich verlangen”—J.S. Bach’s Harmonic Reworkings


When comparing these versions, you may be surprised at the harmonic flexibility of this relatively simple melody and at Bach’s ingenuity in capitalizing on its potential. Each phrase receives harmonic support that clearly delineates the underlying tonality and effectively drives to a cadential repose. How does Bach realize the harmonic potential of the melody? Although there are different answers to this crucial question, it seems that by allowing the melodic phrases to be reinterpreted in the context of closely related key areas and by choosing supporting harmonies that firmly project those key areas, Bach is able to create very different yet compelling harmonic settings. Take, for example, the opening phrase in mm. 1–2. In each case, the pitch E4 that ends the phrase on beat 3 in m. 2 receives distinctive harmonic support. In Figure 25.1a, the E4 is supported by an A major triad, in Figure 25.1b by a C major triad, and in Figure 25.1c, the E4 is harmonized with an E major triad. The choice of these harmonies is predicated on Bach’s ability to select chords that inevitably lead to the respective cadential closures. While the cadence in Figure 25.1a functions quite unexpectedly as a sort of Phrygian half cadence in D minor (without an explicit statement of that key), the other cadential gestures are the consequences of prior harmonic progressions. Thus in Figure 25.1b the melody is reinterpreted as –––––– in C major and receives a harmonic support from this key area, while in Figure 25.1c, the same phrase functions as –––––– in A minor, projects this key with a logical choice of supporting chords, and terminates with a “correct” Phrygian cadence.

Although the independent nature of Bach’s inner voices implies a linear approach to reharmonization, each note of the melody is supported by a single harmonic formation, as indicated by the Roman numerals and lead-sheet symbols. The use of melodic diminutions is purely for decorative purposes and confined to local harmonies only. The vertical aspect of these reharmonizations, then, is conveyed by the fast rate of harmonic rhythm and one-to-one ratios between the melody and harmony. Note also that each of these reharmonizations features chord progressions that logically support the underlying key areas, which—as is often the case with the tonal architecture of chorale melodies—change about every two measures. In short, Bach’s reharmonizations not only capitalize on the harmonic potential of the melody, but they also feature perfectly executed voice leading and unobtrusively support the tonality of individual phrases with a strong cadential confirmation at the end of each phrase.

A very different approach to harmony is shown in Figure 25.2, where the interaction between the three voices creates functional progressions and individual harmonic formations. Figure 25.2 illustrates mm. 1–16 of “Variatio 15. Canone alla Quinta. a 1 Clav.” by J.S. Bach from his “Goldberg Variations.”

The rate of harmonic rhythm is considerably slower with one chord per measure in most cases. The interplay between three independently moving lines creates interesting harmonies that resist a beat-by-beat vertical analysis. Metric displacements, accented passing notes, appoggiaturas, suspensions, and, above all, voice independence (though being a canonic variation definitely helps in this case) are essential features of a linear approach to harmony. The use of these devices creates a sense of harmonic freedom: the many localized harmonies are generated linearly without being confined to individual beats or measures. For instance, mm. 1–4 feature a chromaticized bass span from to which is realized with the traditional chord progression: | i | V6−V | iv6 | V |. When examining the way Bach handles this standard progression, you can see that voice independence plays an integral role in disguising the structure of individual chords. For instance, the occurrence of V6 in m. 2 is postponed by a half beat with a 2–3 bass suspension. In the same measure, the first convergence of three voices at the “and” of beat 2 produces the D augmented triad. The chromatic oscillation in the bass voice in m. 3 between E3–E3, followed by the leap of a diminished 8ve to E4, creates a wonderful harmonic ambiguity and further disguises the underlying predominant harmony. Note that each melodic line is melodically and rhythmically independent, with the bass voice providing clear harmonic support for the upper parts. The use of contrary motion between voices (this piece features a canon at the fifth in contrary motion) and stepwise linear spans that create expressive dissonant intervals (mm. 2, 9, and 15) testifies that Bach is probably more interested in cultivating a sense of linear independence and letting the interaction between individual lines dictate the harmonic outcomes than he is in being influenced and confined by the symmetrical unfolding of harmonic progressions.



FIGURE 25.2 J.S. Bach—“Variatio 15. Canone alla Quinta. a 1 Clav.” from Goldberg Variations


As mentioned earlier, the study of reharmonization is a vast subject and the forthcoming study does not pretend to be even marginally exhaustive. The primary purpose is to bring an awareness to the huge potential that vertical and linear approaches to reharmonization can present.





BASIC REHARMONIZATION TECHNIQUES




* * *



In this section, several approaches to reharmonization will be discussed and illustrated by using sections from Joseph Kosma’s classic tune “Autumn Leaves”:3

1. Addition of extensions

2. Harmonic expansion of structural chords

3. Tonicization

4. Tritone substitutions

5. Diminished 7th chords

6. Upper-structure triads

7. Neighbor formations

8. Pedal points

9. Functional exchange

10.Melodic recontextualization

11.Interpolation of auxiliary progressions.





Addition of Extensions


Chapters 4 and 5 showed how to expand the structure of chords with various extensions and pitch alterations. As a result, 14 four-part chords and 35 five-part chords were introduced. Since the addition of chordal extensions will be demonstrated in the context of “Autumn Leaves,” the pool of available chords for reharmonization will be considerably smaller and entirely dependent on the structure of the melody. The melody of “Autumn Leaves” (and of any other tune) suggests which chordal extensions will work and which ones will not. Figure 25.3 illustrates mm. 1–8 of “Autumn Leaves” copied from a poorly edited fake book.

When trying to realize these chords as faithfully as possible, notice that the realization hardly sounds convincing. If you add appropriate extensions to these chords, however, the progression sounds more idiomatic and in keeping with jazz harmonic practice. To add appropriate extensions, the relationship between the melody and the underlying harmony has to be examined. The notes, E5 in m. 1, D5 in m. 3, C5 in m. 5, and B5 in m. 7, function as minor/major 3rds of the corresponding chords. Notice that each note (with the exception of B4 in m. 7) is suspended over the bar line and supported with a different chord. Did you recognize the familiar voice-leading scenario in which the 3rd of one chord becomes a 7th of the next? Each chord tone on the downbeat of mm. 1, 3, 5, and 7 is prepared by a quarter-note melodic ascent. These melodic ascents occur in the harmonic space of particular chords and, as such, suggest the use of specific extensions that can effectively expand the structure of the underlying chords. Figure 25.4 shows the lead sheet for “Autumn Leaves” analyzed with Roman numerals. The boxed numbers indicate the relationship between melodic notes and supporting harmonies.



FIG. 25.3 “Autumn Leaves” mm. 1–8


Based on this analytical reading, the pool of available extensions becomes more restrictive. For instance, if we were to add a 9th to D7 on beat 3 of m. 6, this choice would create a jarring dissonance with the melodic note, E4. Furthermore, the predominant function of Cmin7 in m. 1 prevents us from adding a major 7th or a minor 6th to that chord. Also, if we add a major 7th to the minor tonic chord in mm. 15 and 31, the presence of G4 in the melody precludes us from adding that chromatic extension, unlike in m. 7 where the melodic B4 would have nicely supported that choice. Figure 25.5 demonstrates the addition of available extensions to mm. 1–8 of “Autumn Leaves.” The melody with the original chord changes is written on the top stave, while the new harmonic progression is realized using Model VI of keyboard playing.

This harmonic expansion is fairly basic and mainly uses a single extension to expand the structure of chords. The only exceptions are F13 in m. 2 and G7alt. in m. 8, where the former uses two diatonic extensions: major 9th and major 13th. The latter is more chromatic and employs 9th and 13th, both of which project the underlying tonality and complement the melody.

What is really fascinating about the addition of available extensions is that one can experiment with different combinations of extensions and voicings to generate different harmonic outcomes. Figure 25.6 illustrates a more challenging selection of available extensions for mm. 1–8 of “Autumn Leaves” using Model VII of harmonic realization. Note that the “chorale style” texture is expanded to five- and six-note voicings.

The Cmin11 chord in m. 1 contains two diatonic extensions: major 9th and perfect 11th. Notice that the voicing of this chord features a quintal structure in the bottom stave that gives the chord a more “transparent” sound. The accumulation of harmonic tension is highlighted by the diatonic extensions. When examining the harmonic content of mm. 3–5, notice some interesting harmonic choices: | BMaj7(5)—BMaj13 | EMaj9(11)—EMaj9 | Amin7(). This reharmonization is possible because the melodic content allows for the use of these specific chromatic formations. The D5 in m. 3, for instance, functions as a major 3rd of BMaj7 and, as such, effectively supports the inner melodic motion from F4 to G4.4 Since m. 3 initiates the inner line, the content of m. 4 is the consequence of the previous measure as the line continues to ascend to A4 and B4. The rather unexpected () harmony in m. 5 is the consequence of suspending the B4 in m. 4 over the min7(5) chord. To put it succinctly, these harmonies are motivated entirely by the melodic content and independent inner lines that cut across the bar lines to supply extensions of the underlying harmonies.



FIGURE 25.4 “Autumn Leaves”—Melodic Analysis




FIGURE 25.5 Addition of Extensions: Variant 1, mm. 1–8




FIGURE 25.6 Addition of Extensions: Variant 2, mm. 1–8


Before leaving this technique, the voice-leading structure of Figure 25.6 must be addressed. Take, for example, the preparation and treatment of extensions in mm. 2–3. The diatonic G4 (major 9th) in m. 2 prepares the F4 (9th) on beat 4 of the same measure. The F4 is suspended over the bar line and becomes a 5th of BMaj7(5), which in turn, initiates the inner line that continues with the suspended preparation of a 9th over Admin7() and a downward resolution to F4 in m. 6. The distribution of extensions is hierarchical; more chromatic extensions require more elaborate preparations. For instance, the 5th — undoubtedly the most dissonant extension of this reharmonization—requires a two-step preparation: from the diatonic 9th to the chromatic 9th and from the chromatic 9th to the more chromatic 5th.





Harmonic Expansion of Structural Chords


One way in which it is possible to generate harmonic diminutions and increase the sense of harmonic motion is by speeding up the rate of harmonic rhythm. Ballads or tunes with slower harmonic rhythms are better suited for the use of harmonic expansion of structural chords rather than tunes with quick moving changes. Broadly speaking, any structural chord with different harmonic diminutions can be expanded. However, your choices must establish a logical relationship with structural chords, anticipate forth-coming harmonies, and occasionally share the same harmonic function. Figure 25.7 illustrates the application of this technique using mm. 1–4 of “Autumn Leaves” realized with Model VII.

Even though chords in mm. 1 and 3 share the same harmonic function, they have different qualities. The Cmin9 and EMaj9 belong to the predominant category of chords and the BMaj9 and Dmin11 belong to the tonic category. In m. 2, the use of the ii7–V7 progression within the dominant 7th space is one of the most common harmonic expansions. It can be freely implemented with any dominant 7th chord provided that the melody allows for such an expansion. These harmonic diminutions produce forward momentum marked by a faster harmonic rhythm, a stronger cadential drive, and a more convincing voice leading.



FIGURE 25.7 Harmonic Expansion of Structural Chords





Tonicization


Tonicization is a technique that prepares the arrival of minor/major key areas or individual chords (dominant 7th, diminished, and half-diminished chords cannot be tonicized) with appropriate dominant 7ths, ii7–V7s, s, or dominant tritone substitutions. As a result of tonicization, harmonic rhythm of the progression speeds up. “Autumn Leaves” features an unusual 32-bar formal design with two four-bar A sections (mm. 1–16) resembling Phrase Model 3 and an extended 16-bar B section (mm. 17–32) approximating Phrase Model 2. The chord structure in mm. 1–8 forms an uninterrupted sequential span that leads to the minor tonic in m. 7. Measure 8, then, is an ideal place to demonstrate the use of tonicization. Figure 25.8 illustrates mm. 7–9 of “Autumn Leaves” realized with Model III.

Even though the tonicization of minor chords requires the progression, the content of the melody in m. 8 prevents the use of this pattern. The melodic span, B4–G4–A4–B4, suggests a ii7–V7 progression, which is typically reserved for the tonicization of major chords. In particular, the pitch A4 does not allow the implementation of Dmin7(5). The pitch B4 on beat 4 suggests the use of an altered dominant and, as the potential source of harmonic conflict, suggests the voicing of the supporting harmony. This places the major 3rd in the middle of its structure to avert the overexposed dissonant clash.



FIGURE 25.8 Tonicization





Tritone Substitutions


Compare the three different reharmonizations of various sections of “Autumn Leaves” in Figure 25.9 using tritone substitutions realized in Model VII.



FIGURE 25.4 Tritone Substitutions—Comparison


When listening to the sound of these substitutions, Figure 25.9a may be the least appealing. In this reharmonization, the relationship between the melody and the tritone substitution is not as convincing as it is in the original chord progression. The pitches F4, G4, and A4 in the context of F7 function as root, major 9th, and major 3rd respectively, and as such create a logical melodic succession. When the same pitch segment is examined in the context of the tritone substitution, these notes become 11th, 13th, and 7th of B7 respectively. There are a few problems with this pitch succession. First, it creates a problematic unfolding of chordal extensions. For instance, a 13th hardly ever resolves up to a 7th. Second, the succession from G4 to A4 demonstrates an incorrect preparation of the chordal 7th in the context of B7. Although the rules of jazz voice leading are not as stringent as they are in common-practice music—at least not on the surface—voice-leading successions like this one should be avoided.

The tritone substitution in Figure 25.9c accommodates the melody notes in a more convincing manner. The pitches B4 and D4 function as a 13th and the root of D7, and a major 9th and a 11th of A7. The melodic succession 9th–11th represents a hierarchical unfolding of extensions from diatonic to chromatic and, as such, makes the use of this tritone substitution more effective than the one in Figure 25.9a. When examining the behavior of outer-voice counterpoint, notice that the outer voices move in parallel motion in Figure 25.9b and in contrary motion in Figure 25.9c. In both cases, the melody notes fit nicely in the context of the underlying tritone substitutions, yet the use of contrary motion in Figure 25.9c is probably more effective. The use of tritone substitutions is first and foremost dependent on the melody. If the melody notes function as chord tones and/or diatonic extensions of the intended tritone substitutions, these substitutions are likely to produce satisfactory reharmonizations.





Diminished 7th Chords


Figure 25.10 illustrates the use of two types of diminished 7th chord: passing and neighbor. This realization utilizes the so-called block style of harmonization. The main characteristic of this style is the use of close-position voicings with the melody doubled at the octave.

The accented diminished passing chord in Figure 25.10a, F°7, connects two chord tones of the underlying harmony: the root and the 3rd. Even though the diminished passing chord typically occupies a metrically weak position, in Figure 25.10a it occurs on beat 3 and adds extra tension to the progression. Figure 25.10b demonstrates the use of two consecutive passing chords, E°7 and F°7. Figure 25.10c shows the use of a lower diatonic diminished neighbor, which is slightly different from the lower chromatic diminished neighbor that occurs in Figure 25.10d. The roots of all diminished 7th chords in Figure 25.10 function as melody notes.





Upper-Structure Triads


The use of upper-structure triads is one of the most powerful techniques that can greatly enhance the character of your reharmonizations. Figure 25.11 illustrates the use of upper-structure triads in mm. 22–23 of “Autumn Leaves” realized with Model VII.



FIGURE 25.10 Diminished 7th Chords




FIGURE 25.11 Upper-Structure Triads


Harmonic hierarchy and voice leading are two of the main themes recurring in our discussion. In Figure 25.11, each consecutive triad is slightly more dissonant than its predecessor. Thus the B triad on beat 2 of m. 22 introduces two diatonic extensions, 9th and 11th, and at the same time prepares the chromatic extensions of the following D by step (albeit, with octave displacements). The choice of parallel and triads on beats 3 and 4 is very effective, as they gradually accrue harmonic tension over F7 before resolving to the chromatic BMaj7(5) in m. 23. The choice of upper-structure triads in Figure 25.11 is entirely motivated by the design of the melody.





Neighbor Formations


Broadly speaking, neighbor formations come in two types: upper and lower. The most important considerations controlling the use of neighbor formations is that they adhere to the rules of voice leading and the behavior of outer-voice counterpoint. Figure 25.12 shows the use of different neighboring formations.



FIGURE 25.12 Neighbor Formations


In both cases, the outer-voice counterpoint features contrary motion and stepwise voice leading. The use of neighbor formations is most effective in situations where the melody moves by step in either direction while the lowest voice moves in the opposite direction to the melody.





Pedal Points


The use of dominant pedal points is restricted to certain types of harmonic progression. These progressions typically feature closely related chords, such as ii7–V7—Imaj7, or Imaj7—vi7—ii7–V7. Dominant pedal points, as the name suggests, utilize the root of V7 as an anchor that supports moving harmonies in upper parts. In a certain sense, pedal points temporarily suspend the succession of chords and allow for the juxtaposition of different chromatic formations. Figure 25.13 demonstrates the use of two pedal points in mm. 17–23 of “Autumn Leaves.”



FIGURE 25.13 Pedal Points


Measures 17–20 feature a dominant pedal point over D while mm. 21–23 suspend the harmonic progression over the F pedal. In both cases, the pedal points are derived from the root of the dominant 7th of the underlying progressions. In addition to being a highly effective reharmonization technique, pedal points are powerful performance-practice devices. Their presence heightens the level of rhythmic activity, invites more interaction between players, renders the underlying progressions as modal (as shown in Figure 25.13) rather than harmonic centers, and allows more chromaticism into the structure of melodic lines. They even justify “playing outside” of the changes.





Functional Exchange


The technique of functional exchange is based on a modification of the expected behavior of chords. These modifications typically involve changing a chord’s quality or function. A successful implementation of this technique depends on establishing a convincing relationship between the melody and the intended harmonic substitution. In general, melodic pitches that in a new harmonic environment function as chromatic extensions are not ideal choices for the implementation of this technique. Figure 25.14 illustrates a harmonic realization of mm. 1–4 with two functional exchanges.



FIGURE 25.14 Functional Exchange


In m. 1, C7(9) substitutes for Cmin7. This choice is not particularly effective because the substitute harmony renders the melodic E5 as a 9th of C7(9). This substitution works if it occurs in the 2nd or 3rd chorus and is foreshadowed well in advance. In m. 3, the BMaj7 chord changes its functional status from that of a local tonic to a dominant 7th anticipating the arrival of EMaj7 in m. 4. The technique of functional exchanges is melody-sensitive and context-specific. Most common functional exchanges involve changing predominant- to dominant-type chords and tonic- to dominant-type chords. (Others, such as dominant- to tonic-type chords are also plausible, although they occur in more advanced harmonic settings.)





Melodic Recontextualization


The technique of melodic recontextualization provides the most striking and easily recognizable harmonic departure from the original chord changes. A successful application of this technique depends on the recontextualization of the melody notes as diatonic chord tones or diatonic extensions of the intended substitute progression. In addition, the newly formed substitute progression should establish a logical relationship with the underlying harmonic motion. Figure 25.15 demonstrates the use of this technique in mm. 1–4 of “Autumn Leaves” using Model VI with rhythmic variations.

The E5 in m. 1 is recontextualized as a major 9th of Dmin9 and a major 13th of G13. This chromatic neighbor progression substitutes the original Cmin7 chord and initiates a sequential progression that continues through the phrase. In m. 3, the Bmin7–E7 progression substitutes the local tonic BMaj7. This substitution is possible because of the diatonic status of D5 in the original and substitute progressions: in the context of BMaj7, the D5 functions as a major 3rd; whereas in the context of the substitute progression it functions as a minor 3rd of Bmin7 and a minor 7th of E7. The voice leading of the progression uses mostly stepwise motion that prepares and resolves all chromatic extensions.



FIGURE 25.15 Melodic Recontextualization





Interpolation of Auxiliary Progressions


The interpolation of auxiliary progressions involves the combination of previously discussed techniques. By now, the idea of melody-specific and context-sensitive harmonic substitutions should be firmly engraved on our musical consciousness. Figure 25.16 interpolates different auxiliary progressions in mm. 1–2 and 7–8 of “Autumn Leaves” using Model VII with different sizes of voicings.

In Figure 25.16a, the melodic E5 functions as a minor 3rd of Cmin9, a major 13th of Gmin13, and a major 3rd of C9. A more advanced interpolation of auxiliary progression occurs in Figure 25.16b. Measures 7–8 combine four reharmonization techniques: the tritone substitution, neighbor formations, tonicization, and melodic recontextualization. The tritone substitution occurs on beat 4 of m. 8 where D9(11) substitutes a tonicizing G7 formation. The tonicization that foreshadows the arrival of Cmin7 in m. 9 should have involved a , yet the melody note A4 implies a ii7–V7 progression. In this case, the tonicizing ii7–V7 progression is reduced to G13sus and followed by D9(11) tritone substitution. The arrival of the quartal structure on beat 1 of m. 8 is anticipated by two neighbor formations, which share the same intervallic properties. This technique is also known as parallel planning. Not only does the melodic recontextualization of B4 in m. 8 as a major 13th of D7 allow for the use of tritone substitution, but it also fulfills the tonal conditions and voice-leading requirements that characterize a successful reharmonization. Since the interpolation of auxiliary progression in m. 8 coincides with the cadential preparation of the new formal section, speeding up the rate of harmonic rhythm makes the arrival of the new section in m. 9 more satisfying.





LINEAR APPROACHES TO REHARMONIZATION




* * *



My ongoing fascination with the contrapuntal pieces of J.S. Bach and D. Shostakovich has led me to develop a linear conception of jazz harmony where the interaction between independently moving voices produces less conventional chords and harmonic progressions. The examples from Bach show that even a single line can successfully convey harmonic progressions.5 The examples from Shostakovich demonstrate that the relationship between non-tonal lines can create interesting, albeit non-functional harmonic progressions.6 Although both composers’ conceptions of harmony are very complex and highly individual, the meticulous design of contrapuntal lines is one of the key features of their respective styles. Their lines are characterized by a balanced design, careful treatment of dissonances (which in Shostakovich’s case are entirely contextual), stepwise architecture, and strong metric and rhythmic properties.



FIGURE 25.16 Interpolation of Auxiliary Progressions





“All the Things You Are”


To demonstrate a linear approach to reharmonization, mm. 1–8 of “All the Things You Are” will be used. First, the melody is harmonized with different lower-voice counterpoints. These two-voice contrapuntal frameworks in 1:1 melodic ratio are then filled in with inner lines moving in half and whole steps. The resulting four-, five-, or six-voice realizations feature both tonal and non-tonal harmonic progressions characterized by linearly derived chords. Figure 25.17 illustrates the A section of “All the Things You Are” with eight note-against-note counterpoints. Notice that the melody is reduced to its essential structure with whole notes only.



FIGURE 25.17 Linear Approach to Reharmonization: Outer-Voice Frameworks


When comparing the structure of the lower counterpoint in Figure 25.17a to other counterpoints, notice that they exhibit more linear characteristics. For instance, the counterpoint in Figure 25.17b moves entirely by half steps starting on the root of the underlying Fmin7. The counterpoint in Figure 25.17c moves also by half steps, yet the opening pitch suggests a chord—scale relationship different from the original. A similar scenario occurs in Figure 25.17d where the opening note of the counterpoint begins on G3 forming the interval of a minor 9th with the melody. Figure 25.17e–f illustrates sequential counterpoints that complement the melody nicely. The former uses a minor 3rd sequence while the latter alternates between major and minor 2nds. Finally, Figure 25.17g–h demonstrates the use of an oblique motion utilizing two pedal points. The choice of tonic pedal point in Figure 25.17g suggests a more conventional reharmonization. The use of D3 as a pedal point in Figure 25.17h, however, implies a reharmonization outside of the conventional norms.

In “fleshing out” these outer-voice frameworks, the behavior of inner lines is restricted to stepwise motion in either direction or to common tones. For now, leaps are forbidden (except for those occurring in the melody). By adhering to these particular constraints, the voices are prevented from converging on to familiar harmonies. Even though dissonant formations are likely to occur, the larger point is to show how lines produce harmonies and how the flow of harmonic tensions is regulated and resolved.

Figure 25.18 provides eight reharmonizations of the outer-voice counterpoints from Figure 25.17.

These reharmonizations draw on some of the techniques discussed earlier in the chapter. For instance, the realization in Figure 25.18c uses the technique of melodic recontextualization as the opening chord renders the melodic note, A4, as a major 9th of Gmin11. In choosing the opening sonorities, familiar structures were avoided in order to experiment with linearly driven harmonic progressions. In a certain sense, the opening sonority sets the character for the entire reharmonization and, at the same time, offers a challenge to find satisfactory harmonic solutions. When comparing Figures 25.18a and 25.18e, the difference between the two is very striking. Whereas the former is more conventional because of the tonal framework, the latter is highly dissonant with largely unanalyzable harmonic formations.

“STELLA BY STARLIGHT”—A REHARMONIZATION




* * *



Written by Victor Young for the movie The Uninvited, “Stella By Starlight” has become a favorite standard tune in jazz. Its popularity among jazz musicians is indisputable; almost all of the great jazz artists of the 1950s and beyond recorded it at some point of their career.7 The lead sheet of the song is provided in Figure 25.19.

The selection includes three sets of changes: movie soundtrack, original, and jazz. By including these changes, we can compare the differences between them and appreciate the composer’s original harmonic intentions. Let me first clarify the labeling of the individual progression. The movie soundtrack changes refer to the progression that is heard in the movie. The song is performed in the key of D major with lavish orchestration and distinct chord progressions comparatively different from both the original and the jazz versions. The original chord changes—supposedly provided by the composer—were published in a fake book in the 1950s (of an uncertain origin) in the key of G major.



FIGURE 25.19 Lead Sheet—“Stella By Starlight”


The jazz changes are readily available in countless fake books and are the ones commonly used by jazz musicians.

What makes “Stella By Starlight” stand out among other standard tunes is its freely unfolding melody, an entity in and of itself that transcends the boundaries of the phrase structure. The melody is characterized by a relatively static rhythmic design and the inclusion of non-harmonic tones as essential melodic components. Suspended notes over the bar lines create tension with the underlying harmonies. Thus the pitch A4 at the beginning constitutes the major 7th of the original B° or the 11th of Emin7(5) of the jazz version. In m. 5, the same harmonic change in the original and jazz versions, F minor, supports the pitch G4, the major 9th. These dissonances usually underscore important words of the lyrics, lending them a particular poignancy. The climax of the tune, occurring in mm. 17–19, corresponds to the lyrics, “that great symphonic theme”; at this point, the melodic E5 becomes the 13th of G7 and F5 the 11th of Cmin11. Measures 20–23 continue to emphasize non-harmonic tones within the melody. Upon reaching in m. 19, the melody features a stepwise descent to in m. 25. This diatonic span, however, receives an unorthodox harmonic treatment: in m. 21, is the major 7th of Emin7 in the original version, or the 11th of A7 in the jazz version; and in m. 23, is supported as the 9th of BMaj7 in both versions.

At first glance, the comparison of the original and jazz changes seems to reveal significant differences between the two. Upon closer examination, however, the jazz changes are seen as a middleground elaboration of the original progression. Nowhere is the relationship between the background and middleground more evident than in mm. 1–8. The opening progression of the original version, B°–F7, stands out for its stylistic uniqueness and an ominous sound perfectly suited to a ghost story. Its connection to the jazz changes, Emin7(5)–A7–Cmin7–F7, is classified through common-tones relationships between Emin7(5)–A7 and B°, as the members of the B° triad are embedded within the structure of A7(9). Since it is common in the jazz idiom to precede the dominant 7th with its local predominant ii7 (provided that melodic notes agree with the harmony), the use of an Emin7(5)—A7 progression is a well-considered choice for the original B°. Similarly, the space occupied by F7 in the original version is expanded by an embedded ii7–V7 progression. Hierarchically, B° is inferior to F7, since the former, due to its unstable quality, is heard as a contrapuntal elaboration of the more stable F7.

The evolution of the jazz harmonic syntax from the popular song vocabulary cannot be more evident than in the treatment of IV–V or IV–I harmonic progressions. These are typical of common-practice tonality and the language of popular tunes draws extensively on this practice. There are specific instances pointing to this practice in “Stella By Starlight.” For instance, mm. 15–16 tonicize G7 in m. 17. The original version employs a local iv–V7 of G. In the jazz version, however, the focus is placed on the cycle of 5ths progression with substituting for iv. A similar scenario occurs in mm. 27–30 where local iv–V7 progressions in the original are changed to in the jazz version. Measures 21–24 in the original are governed by a iv–I harmonic motion. The relatively weak position of the plagal motion (further emphasized by a minor predominant) is replaced by a more idiomatic VII7 in m. 21. The use of the back-door VII7 is consistent with idiomatic jazz practices and anticipates the arrival of the tonic more forcefully. Again, the use of the jazz substitution stems from the original change; Emin may be interpreted as a “ii7” necessarily bringing its “V7,” A7.

The movie soundtrack and original changes are very much related to one another. The former, however, makes great use of chordal inversions and linear bass progressions. For instance, the preparation of the climax in m. 17 begins in m. 9 with the chordal 5th over the B triad. The bass voice subsequently descends to G in m. 17. During this span, it introduces some compelling harmonies, which are quite unexpected, yet masterfully woven into the framework of the progression. In m. 12, D7(5) nicely anticipates the F/C. The free standing B° in m. 14 offers convincing melodic support and foreshadows the arrival of Amin7(5).





FIGURE 25.20 “Stella By Starlight”—A Reharmonization


As a ghost movie theme, “Stella’s” dreamy and mysterious character is expressed in many different ways. The reharmonization of the song in Figure 25.20 attempts to capture its mood through the harmonic vocabulary derived from the hexatonic system discussed in Chapter 20. Remember, the hexatonic system includes major, minor, dominant, suspended, and intermediary categories, each of which features a pitch aggregate that furnishes material for voicings of different sizes and intervallic configurations. In general, the voice leading of the reharmonization is mostly stepwise and balances a mixture of contrary, parallel, and oblique motions occurring between the voices.

NOTES



* * *



1. A comparison of different harmonic settings of the same chorale melody enables one to appreciate J.S. Bach’s conception of harmony. An examination of larger compositions, such as Bach’s Goldberg Variations, BWV 988; Beethoven’s Diabelli Variations, Op. 120; Chopin’s Variations on “Lá ci darem la mano,” Op. 2; Brahms’s Variations and Fugue On a Theme By Handel, Op. 24; or Mompou’s Variations On a Theme By Chopin reveal how these composers exhausted the harmonic and contrapuntal potential of the melody with which they were working.

2. 178 Chorale Harmonizations of Joh. Seb. Bach—A Comparative Edition for Study, Volume I, by Donald Martino is an excellent publication that compiles multiple harmonic settings of chorale melodies that allow for easy comparison. This inexpensive publication is strongly recommended.

INTRODUCTION




* * *



“Line Up” is an overdubbed solo performed by Lennie Tristano with a pre-recorded rhythm section.1 The solo is a superb demonstration of an important style of improvisation, which, above all, is characterized by a highly innovative approach to rhythm and meter. The remarkable feature of the Tristano school, whose illustrious alumni include Lee Konitz, Warne Marsh, Billy Bauer, and others, is that it lends itself to improvisation as much as it does to composition. In fact, contrafacts such as “Lennie’s Pennies” and “317 East 32nd Street” composed by Tristano, “Subconscious-Lee” and “Kary’s Trance” written by Konitz, or “Marshmallow” and “See Me Now, If You Could” composed by Marsh, sound like improvisations worked out in advance.

“Line Up” exemplifies the essence of the “Tristano style” and, as such, constitutes a great pedagogical tool for summarizing various characteristics of jazz musical syntax discussed in this book. It also demonstrates how specific theoretical concepts work in practice. You will be surprised at the amount of information encoded in this solo and how much you can learn by cracking Tristano’s musical code. In the forthcoming analysis, the discussion focuses on the aspects of his playing that have practical applications and eventually leads to a broader codification of his style of improvisation.





ANALYTICAL ANNOTATIONS




* * *



Figure 26.1 shows a partially annotated transcription of Lennie Tristano’s “Line Up.” To facilitate comprehension, various analytical markings and symbols are used. Neighbor figures prepare chord tones or structural tones by step from below and/or above. In the transcription, UN indicates upper neighbor, LN lower neighbor, and DN double neighbor (which some jazz musicians also call pitch enclosure). Double-neighbor figures typically involve three- or four-note groupings, but in the case of longer gestures, they are designated EDN (extended double neighbor). The chord tone decorated with a neighbor figure is analyzed with an Arabic number written in parenthesis to show its chord membership. Somewhat related to neighbor figures is the escape note, EN, which leaves a chord tone with a step and resolves to another chord tone by a skip in the opposite direction. In addition to neighbor and escape notes, Tristano employs a variety of passing notes, PN. Those derived from bebop scales are designated BPN (bebop passing notes). In the score, passing and escape notes are placed in parenthesis and analyzed accordingly. Occasionally, D (diatonic) and C (chromatic) are written in front of LN, DN, PN, etc.: for instance, CUN stands for chromatic upper neighbor, DDN for diatonic double neighbor, etc. In the case of accented figures, A written in front of the symbol is used: ALN indicates accented lower neighbor, ACPN accented chromatic passing note, etc.

Neighbor figures often occur in the midst of a phrase, making them difficult to isolate from the surrounding notes; they are therefore marked by slurs in the score. Dashed slurs show various scalar passages, such as modes, bebop scales, pentatonics, chromatic segments, melodic patterns, and characteristic gestures. Dotted slurs indicate prolongation of notes across larger sections of music and a stepwise voice-leading connection between (with possible octave transfers) adjacent phrases. Brackets below the score are reserved for chord arpeggiations and harmonic substitutions, which are analyzed with additional chord symbols, scale degrees, and Arabic numbers. Chords written below the brackets represent harmonic departures from the underlying progressions. These departures are essential to Tristano’s style and include: superimposition of chromatic structures (three-, four-, or five-part), harmonic sequences, and chromatic sidesteppings. Chromatic sidesteppings are indicated with vertical arrows pointing to the direction of a departure from the structural harmony. For the purpose of readability, these departures are analyzed with enharmonic chord symbols, which do not coincide with the structurally appropriate spellings.

Scale degrees specify important tones in the tonic key and underscore structural melodic spans or motifs occurring at the background level. For instance, stands for the melodic span F–F♭–E♭ in the key of A♭ major. There is frequently a lot of melodic activity at the surface level between structural tones; therefore, these tones are marked with longer stems connected to a horizontal beam. Dashed stems indicate non-structural notes, such as local chord tones or melodic patterns connected to a horizontal beam. Arabic numbers are utilized for specific pitch successions occurring over local harmonies. For instance, a C:1–2–3–5 illustrates a C–D–E–G melodic pattern. Figure 26.1 contains the summary of all the abbreviations and symbols used in Figure 26.2.





AN ANALYSIS OF THE TRANSCRIPTION




* * *



When listening to the recording of “Line Up,” notice the inherent complexity of Tristano’s lines, their incessant drive, and their swinging quality. As had been the case with numerous instrumental contrafacts from the Bebop Era (and definitely was the prevalent compositional strategy of his school), Tristano borrowed the chord progression from the repertory of standard tunes. In this case he chose “All Of Me” by Gerald Marks and Seymour Simons. An interesting fact about “Line Up” is the absence of a clearly defined thematic statement at the outset of the piece. With each passing chorus, the music seems to build up a forward momentum, giving listeners numerous jolts by shifting to chromatic key areas or engaging in complex rhythmic displacements. With the exception of a few places (mm. 97–104 and 149), the solo employs a single-line texture, which makes it ideal for studying and performing by different instrumentalists. But what is truly fascinating about “Line Up” is that, in spite of the listener’s initial reaction to its complex nature, Tristano uses relatively simple melodic ideas that he effectively synchronizes with different structural patterns. He employs a variety of rhythmic devices that give the solo an innovative character and fully capitalizes on the relationship between melody and meter. The interplay between melody and meter occurring at various levels of the musical fabric is the driving force behind this solo, which demonstrates Tristano’s heightened awareness of musical discourse.





Rhythmic Displacement


The idea of rhythmic displacement is central to the “Tristano style” and is announced in the very first phrase of his seven-chorus tour de force solo. The line begins in m. 9 with an iambic rhythmic motive, which is immediately answered in m. 10 by an anapestic figure.2 The placement of the anapestic figure on beat 4, coupled with an accent on the first note, makes the entire phrase sound metrically ambiguous, almost as if the beat got turned around. By displacing the second half of the phrase by a beat, Tristano cleverly overrides the predictable phrase symmetry and, with relatively simple melodic means, begins his solo in a highly original manner. Play the opening phrase with a metronome and pay close attention to the way the accents and note placements influence the overall perception of the underlying meter. To compare how the phrase might have sounded if Tristano had retained the expected phrase symmetry without rhythmic displacement, start the second phrase on beat 1 in m. 11.





FIGURE 26.1 Analytical Symbols and Annotations





FIGURE 26.2 “Line Up”—Lennie Tristano (transcribed by Dariusz Terefenko)

Tristano explores the concept of rhythmic displacement using different improvisational strategies, such as phrase displacement, metric displacement, manipulation of phrase accents, and melodic interpolations. Phrase displacement occurs when the phrase is shifted by a beat (or more) and creates a dissonance with the underlying harmonic and metric structure. Probably the most effective use of this technique occurs in m. 77 where the line begins on beat 2 with a downward arpeggiation of the E major upper-structure triad over the structural B♭7 and is further emphasized with a strong accent on the first quarter note, E♮4. The manipulation of phrase accents shifts regular metrical accents, thereby creating metric ambiguity. This technique occurs when the phrase temporarily renders beats 2 and 4 as beats 1 and 3. The phrase in mm. 159–160 illustrates these features. Notice how beat 4 in m. 159 influences the perception of beat 2 in the next measure.

Metric displacement implies the use of cross rhythm to create a characteristic rhythmic jolt and increase in tension within the phrase. The phrase in mm. 81–83 displays these characteristics. The distribution of accents and phrase groupings in mm. 81–83 creates an interesting superimposition of 3/4, 3/8, 2/4, and 4/4 respectively. Notice how the use of 3/8 influences the metric location of sub-phrases in 2/4 and 4/4 in mm. 82–83, and how the perception of the meter in the ensuing measures is constantly being challenged.





Melodic Interpolation


Melodic interpolation is a relatively straightforward improvisational technique based on the addition and often repetition of a few notes in the midst of a phrase that results in subsequent rhythmic displacement. The two-note melodic interpolations in m. 57 and mm. 116–117 demonstrate the use of this technique.

The simplicity of Tristano’s melodic ideas is truly remarkable. These ideas vary from simple triadic arpeggiations (mm. 97–99), diatonic scalar patterns (mm. 13–15), and pentatonic scales with chromatic passing notes (mm. 65–67). Hand in hand with these simple devices goes the manner in which Tristano terminates his melodic lines. The repository of his melodic cadential gestures is quite impressive and includes various intervallic skips (mm. 95, 124, 156, 224), stepwise descents (mm. 147–148, 167), and neighbor figures (mm. 63, 177, 184).





Playing Outside


Along with rhythmic displacement, playing outside of the underlying tonality is another hallmark feature of Tristano’s style of improvisation and results in his highly original approach to chromaticism. In “Line Up,” the use of chromaticism is pervasive, yet the manner in which Tristano controls it deserves attention. Just like his use of rhythmic displacements, Tristano’s use of chromaticism is elegant and logical. When his lines temporarily leave the underlying tonal area and venture into a chromatic space, they retain strong melodic and harmonic identities and remain inside of the outside key areas. Figure 26.3 compares two phrases from mm. 25–27 and 63–68.





FIGURE 26.3 Playing Outside

Notice how similar these chromatic departures are. In the former, Tristano employs C♯3 (enharmonic D♭3) to access the chromatic neighboring area up a minor 2nd from the structural harmony D♭6/9. As a common tone between the two key areas, C♯3 functions as the root of D♭6/9 and the major 7th of DMaj7, and as such constitutes the ideal choice for connecting these key areas. During mm. 65–66, the chromatic upper neighbor harmony A6/9 embellishes the A♭6/9 harmony, capitalizing on a common-tone reinterpreta-tion and an intricate double-neighbor preparation. Although the top of chorus 3 begins with a chromatic neighbor harmony without prior preparation, the opening note E♮3 is a half step away from the previous note in m. 63 and thus establishes a smooth voice-leading continuation between adjacent phrases. In m. 65, what seems to be excessive chromaticism on beats 3 and 4, turns out to be an intricate pivot area where the two keys, A and At♭, converge and interact. This pivot area hovers around . On the one hand, the segment C4-D♭4-D♮4-C4 in m. 65 functions as a double-neighbor figure foreshadowing the occurrence of C♯4 on beat 1 in m. 66; on the other, it reminds us that the line is still in the key of A♭ major. Notice the overall melodic flow and phrase contour of these two measures. Beats 1 and 2 of m. 65 initiate a pentatonic segment in A major, beats 3 and 4 introduce a double-neighbor pivot area. Beats 1 and 2 of m. 66 return to the same pentatonic segment as m. 65 in the opposite direction, and continue onward, via a half-step re-entry, to a resolution in m. 67 with a double-neighbor figure encircling .





Structural Approach


Some of Tristano’s phrases, such as in mm. 13–15, 33–36, 105–112, 125–131 and others, have an intricate architecture and demonstrate what can be described as a structural approach to improvisation. These spans provide structural frameworks for surface melodic elaborations, thereby giving the solo remarkable coherence. When you consider that these spans can, and often do, contradict the predictable phrase symmetry and, in more advanced situations, can even disguise the formal boundaries, the benefits of using this approach in practice is evident. What transpires in mm. 13–15 is a basic illustration of a structural approach to improvisation. The melodic pattern controls the surface melodic elaborations, which basically consist of simple upper diatonic neighbors and a single escape note. A similar approach occurs in the context of a compound melody in mm. 33–36. Here, the span begins in the lower voice and is subsequently answered by the melodic pattern 8–♯7–♭7 from C7. At the same time, the upper voice of this seemingly polyphonic texture emphasizes the 5th of the corresponding chords with interesting note placements that create additional metric ambiguities. On the local level, the pitch C♭3 in m. 108 is the part of a chromatic double-neighbor figure flavoring the local submediant harmony with the characteristic ♭5. Concurrently, the same note also participates in the extended double-neighbor figure in mm. 105–112.

A far more advanced implementation of the structural approach to improvisation occurs in mm. 125–131, where the pattern cuts across the formal boundaries and connects choruses 4 and 5. The phrase reaches in m. 127 and embellishes it with an upper diatonic neighbor in m. 128; the phrase subsequently descends, via on beat 4 in m. 128, to in m. 129. While the structural span seems to have ended in m. 129, an upward registral shift to on beat 3 in m. 129 and its descent to in m. 131 replicate the upper-neighbor motion from mm. 127–128. Scale degree one, then, functions as a pivot note that connects the two double-neighbor figures: and .

In order to be successful with this approach to improvisation, it is necessary to imagine a structural line that moves mostly by step in larger note values and establishes a convincing chord-scale relationship. The creation of structural lines depends on the ability to hear and to isolate them from the underlying chord progressions, and, subsequently, to embellish them with different melodic ideas.





Advanced Techniques


Tristano employs more advanced techniques of improvisation, particularly in later choruses. These techniques include unprepared chromaticism, harmonic interpolations, manipulation of harmonic rhythm, superimposition of chromatic progressions, motivic parallelism, and compound melody. Unprepared chromaticism occurs in m. 185, where Tristano begins his line up a minor 2nd from the structural harmony D♭6/9. Although he does not prepare this passage immediately, Tristano anticipates it in the previous choruses. Harmonic interpolation expands the underlying chord structure with substitute chords or new chord progressions. In “Line Up” these interpolations are relatively easy to spot because Tristano clearly delineates them with straightforward arpeggiation or other easily recognizable melodic patterns. The most striking use of this technique occurs during mm. 201–206, where the succession, | Dmin(♯7)–C♯min(♯7)| C6/9| F♯min(♯7)| Fmin6–D♯ø7 | Dø7 | BMaj7 |, expands the underlying C7–Fmin7–B♭7 progression.

Tristano’s manipulation of harmonic rhythm is born out of his horizontal approach to improvisation and comes in two guises: harmonic displacement and harmonic omissions. The former is based on the placement of regularly occurring chords on metric locations different than expected. The latter omits certain structural chords altogether, giving priority to the independent nature of melodic lines. Some of Tristano’s lines are unconstrained by the predictable symmetry of chord progressions and display a fair amount of linear independence. In disregarding certain structural harmonies, Tristano demonstrates how lines influence the harmonic outcome and not the other way around. In m. 37, for example, the melodic line continues in the harmonic space of C7 begun in m. 35 and only gradually merges with the underlying harmony F7. The superimposition of chromatic progressions in place of structural chords is an effective technique that can be implemented to introduce controlled chromaticism into your own playing. It requires the use of simple melodic devices, such as in mm. 215–216, where the G♭7–C♭Maj7 and F7–B♭min7 progressions are clearly superimposed over the structural B♭min7 harmony.

Motivic parallelism is a technique that affects the musical surface and background. The use of motivic parallelism at the background level is quite common in composition, but when it happens in the context of improvised music it proves the advanced artistry of the improviser. On a more local level, an pattern in m. 138 is immediately answered by a pattern in the same measure. Scale degree three on beat 4 of m. 139 initiates an enlarged version of a half-step motive utilizing the blue 3rd on beat 4 of m. 140. These illustrate how salient intervallic gestures—in this case, a minor 2nd down—influence the unfolding of the melodic phrase. In mm. 189–190, Tristano introduces a background span, , and immediately repeats it in an incomplete form and with subtle metric displacements in mm. 191–192.

Motivic parallelism also indicates surface devices that reappear throughout the solo—one’s favorite melodic devices, so to speak. For instance, the four-note figure with two ascending half steps followed by a larger intervallic skip in m. 45, mm. 142–143, and m. 207 (slightly varied), or the 1–2–3–5 melodic patterns in mm. 27, 30, 69, 123, 163, 217, etc., show Tristano’s penchant for these types of surface device. Yet, in comparison to the more structural use of motivic parallelism, they seem like simple recurrences of familiar and well-internalized melodic patterns.

The use of compound or polyphonic melody adds another level of complexity to his solo and demonstrates Tristano’s contrapuntal approach to improvisation. This technique implies the use of two-voice texture in the context of a single-line melody. Figure 26.4 illustrates a voice-leading reduction of mm. 157–161.

The upper voice forms a melodic span that cuts across the formal boundaries. Scale degree two in m. 158 becomes temporarily suspended and the melodic activity is transferred to the lower voice with a diatonic scalar descent. In mm. 159–160, the lower voice forms a melodic ascent embellished with unfolding thirds, which also contributes to the polyphonic nature of the phrase. At the top of chorus 6, is restored and resolves down to on beat 2. The cadential gesture A♭3–E♭3 on beat 2 of m. 161 unifies the two melodic strands. One of the conditions for the use of the compound melody is a clear registral separation between the implied voices.





FIGURE 26.4 Compound Melody

The treatments of chromaticism and of voice leading are intimately related to one another and are essential elements of Tristano’s cultivated approach to improvisation. Notice how he introduces chromatic segments into his lines in mm. 16 and 41. In m. 16, Tristano arpeggiates D♭Maj9 as an upper structure of E♭7, which contains three diatonic extensions: 9th, 11th, and 13th. On the way down, he supplies chromatic versions of the two extensions, ♭13th and ♭9th, and resolves the perfect 11th down to a major 3rd. These linear connections occur in the same register. When the line enters the chromatic region in m. 41, Tristano uses an octave displacement preparation as the diatonic B♭2 from m. 40 foreshadows B3 at the outset of the chromatic departure in m. 41. Even though there is an upward octave leap in this preparation, it is perfectly justifiable from a voice-leading perspective.

Tristano’s lines are notoriously long; observe the one running uninterruptedly in mm. 81–91. Within this melodic stretch, Tristano creates a nicely balanced line that features the measured use of stepwise motion, arpeggiation, and chromaticism. In addition to all this, Tristano’s playing swings hard—a trait that anyone can (and should) admire.

INTRODUCTION




* * *



Twentieth-century music offers an amazing variety of styles, harmonic languages, and compositional techniques. As such, it can be used by jazz musicians to broaden their musical horizons, expand their harmonic and melodic vocabularies, and experiment with different compositional methods. Post-tonal theory encompasses numerous theoretical systems that seek to explain the nature of different kinds of twentieth-century music. Presently, we will concentrate only on one particular type of twentieth-century music, so-called atonal music, and its corresponding theory.1 The atonal period is usually identified with the composers of the Second Viennese School: Arnold Schoenberg, Anton Webern, and Alban Berg. Its golden age lasted for about 17 years, from ca. 1905 until 1922. Atonal music is characterized by unordered pitch relationships. The use of atonal music theory implies that the familiar topics of note names, intervals, chord formations, and others are recontextualized in order to convey the uniqueness of that system. For instance, triads are referred to as trichords, notes are labeled with integers (not by their traditional letter, scale-degree, or solfège names), and intervals are measured with numbers indicating semitone count. These nomenclatural changes are necessary to reflect the nature of atonal music, in which traditional tonal relationships are generally absent.





BASIC CONCEPTS




* * *





Integer Notation


Figure 27.1 shows the notes of the chromatic scale labeled as integers. The pitches A♯ and B use a “t” and an “e” to represent integers ten and eleven, respectively.

In atonal music, the difference in note spelling is not as crucial as it is in common-practice music. The concept of enharmonic equivalence enables us to use the same integer for different spellings of the same pitch. For instance, C♯ and D♭ are enharmonically equivalent and are both referred to as pitch class 1 or pc1; A♯ and B♭ are enharmonically equivalent and referred to as pct.





Pitch and Pitch Classes


In our study of post-tonal jazz, the designation “class” is frequently encountered. It signifies an abstract representation that combines shared characteristics of a pitch, an interval, or a chord. A pc3 combines all E♭s, D♯s, and F♭♭s, regardless of their location on the staff, timbre, or other musical characteristics. The differentiation between pitch and pitch class refers to the distinction between a literal sounding pitch and an abstract pitch class that combines all like-sounding pitches. Think of all the Gs on the piano, for instance: there are seven distinct pitches that are members of the class pc7. Figure 27.2 illustrates notes between C3 and C6, notated as pitches and pitch classes.



FIGURE 27.1 Integer Notation



FIGURE 27.2 Pitch and Pitch Classes





Intervals and Interval Classes


Intervals in atonal music are labeled and measured differently than they are in tonal music. Pitch intervals measure the distance between two pitches. There are two types of pc interval: ordered and unordered. An ordered pc interval occupies the distance between two pitch classes in ascending order or clockwise direction. For instance, an ordered interval between pc1 and pce is 10, and between pce and pc1 is 2. A formula pcy–pcx, where y stands for the second interval out of the two, helps to make those simple calculations. There are 12 ordered pc intervals.

An unordered pc interval is related to interval classes, which, as the designation “class” implies, represents a further abstraction of intervals. Since each pc interval can be inverted to generate its complement, there are only six interval classes, each combining an interval and its inversion. An unordered pc interval constitutes the smallest interval out of the two. The unordered pc interval between pc1 and pce is 2 because interval class 2, written as ic2, combines two intervals—10 and 2—with the smallest one being chosen. Figure 27.3 illustrates traditional interval names, 12 ordered pc intervals, and six unordered interval classes. We will use unordered pc intervals, or interval classes, when implementing concepts from the atonal music theory.



FIGURE 27.3 Ordered and Unordered Intervals





TRICHORDS




* * *



In tonal music, root position triads are considered as being organized in ascending order and in the most intervallically packed manner possible. To figure out the root position of the pitches, F♯, D, and A, for example, put the unordered collection in ascending order: D, F♯, A, or [269] using integers. For the purpose of representing atonal relationships changing the order in which pitches occur is allowed. In other words, a trichord in root position is analogous to the most packed arrangement of pitches of that trichord in ascending order, or any other trichord or pitch-class set (henceforth, pc set) of any cardinality. Cardinality refers to the number of pitches, without pitch duplicates, occurring within the set. The trichord [269] is said to be in the normal form, which represents the unordered collection of pitches: F♯, A, and D. The normal form refers to the most intervallically packed arrangement of pitches in ascending order of a pc set of any cardinality.

When examining the intervallic content of [269], notice the interval classes 4 and 3 between the adjacent pairs of pitches: pc6–pc2=ic4 and pc9–pc6=ic3. What does the intervallic content of a pc set tell us? It tells us whether the pc set is symmetrical or not and whether the trichord [269] has an inversional partner or not. The intervallic content of [269] can be written as ic<43>. Note that square brackets are used to represent the normal form of a pc set and pointed brackets to represent the intervallic content of a pc set. The trichord [269] comprises two different interval classes: ic4 and ic3, which means that [269] is asymmetrical and has an inversional counterpart. How do we determine which trichord is inversionally related to [269]? The easiest and quickest way is to reverse the order of interval classes from ic<43> to ic<34>. When we represent ic<34> as a pc set starting on pc4, for instance, the result yields the following set: E, G, and B or [47e]. Notice that [47e] is a minor triad and the original set [269] is a major triad. In atonal music theory, these two normal forms: [269] and [47e] belong to the same set class. This conclusion is based on the fact that the intervallic content of two sets [269] and [47e] is exactly the same. Remember that in atonal music, the order in which intervals and pitches occur within a set does not affect the interpretation of that set.

In atonal music theory the difference between major and minor qualities is of little significance, simply because major and minor triads, as well as other formations—dominant 7th and half-diminished 7th chords—are inversionally equivalent and belong to the same set class. When the adjacent intervals of [269], ic<43> and [47e], ic<34> are compared, it is immediately evident that these two trichords are identical in terms of their unordered intervallic content. To figure out the next and final level of abstraction of a pc set called the prime form, (1) put an unordered pitch collection in the normal form, and (2) calculate the intervallic content of that set. Based on this information, examine whether a pc set has an inversional partner or not. If it does, compare their intervallic content to determine which one is the most packed. Finally, select the most packed set and transpose it to pc0. Prime form or set class always starts on pc0 and its pc content is written in parenthesis.

The pc set [47e] is more intervallically compressed than its inversional partner, [269]. When the [47e] is transposed to pc0, the prime form is obtained. When we speak of (037) as the prime form, we are referring to an abstract entity—a set class—that contains 24 distinct normal forms: 12 transpositionally related [037]s with ic<34> and 12 inversionally related [047]s with ic<43>. Each one starts on a different pitch of the chromatic scale, known as the aggregate. Think about 12 unique major and minor triads as belonging to a single set (037). In the case of symmetrical trichords, such as (024), whose intervallic content yields ic<22>, the set class (024) contains only 12 distinct [024]s built on each note of the aggregate. The (024) is symmetrical and the inversion in pitch-class space yields the same pc set.





Methodology for Figuring Out Normal and Prime Forms


1.Translate any unordered collection of pitches to pitch classes.

2.Put pitch classes in ascending order in the most packed arrangement (i.e. root position formation).

3.The resulting pc set is in the normal form, which accounts for the actual sounding, yet unordered pitches of that set.

4.Figure out the unordered intervals (i.e. interval classes) between adjacent pitch classes and determine whether that set has an inversional partner or not.

5.If the answer is yes, select the one that is the most packed in ascending or descending direction.

6.Transpose the most packed set to pc0.

7.The resulting set is in prime form.

8.The prime form is synonymous with set class.

9.Depending on the intervallic content of a pc set, the prime form might include 24 transpositionally and inversionally pc sets, or 12 transpositionally related pc sets only.





“Clock Face” as a Visual Aid to Identify Sets


Figure 27.4 shows a “clock face” that expedites the process of calculating normal and prime forms. Since the clock face has 12 positions corresponding to the 12 pitch classes, it can be quickly drawn and used to locate the pitch classes of a set.

Given pc7, pc2, and pc6, for instance, it is easy to determine the most packed arrangement of these notes simply by visually examining the set. When examining the collection clockwise (ascending order), notice that by starting at two o’clock, pc2, then moving to six o’clock, pc6, and finally to seven o’clock, pc7, we get the normal form: [267] with ic<41>. Counterclockwise examination (descending order) starting at seven o’clock, pc7, however, reveals an even more packed intervallic arrangement: the unordered interval between pc7 and pc6 yields ic1, and between pc6 and pc2 is ic4. To calculate the prime form, then, we basically assign pc0 to pc7 and count counterclockwise to determine the integers of the remaining pitch classes: pc6 becomes pc1, and pc2 becomes pc5. Set class (015) is the prime form of [267]. That method is much faster and, with some practice, it speeds up the translation of any pc set to normal or prime forms. To generate the prime form, then, assign a movable pc0 to the first note of the most packed arrangement of pitch classes and figure out the position of the remaining pitches. Figure 27.5 demonstrates this process on a clock face.



FIGURE 27.4 The “Clock Face”



FIGURE 27.5 Prime Form on the “Clock Face”





FAMILIES OF TRICHORDS




* * *



One of the most remarkable things about set classes is their reductive power and ability to represent a vast array of harmonic structures using only one set class. This means that endless configurations of three unordered pitches can be reduced to the 12 distinct transpositionally and inversionally related set classes shown in Figure 27.6.





FIGURE 27.6 Families of Trichords: Integer Notation



These set classes are compartmentalized into four unique families of trichords that share certain intervallic features and suggest a possible membership in specific harmonic environments. The “diatonic” family of trichords comprises two pc sets: (025) and (027). In addition to their independent status, these and other trichords are thought of as subsets of larger supersets, such as pentatonic, hexatonic, modal, and octatonic scales, which in itself is an important characteristic that may be explored in improvisation and composition. Even though they are labeled as “diatonic,” (025) and (027) can intersect with more chromatic supersets as well. The whole-tone family includes three set classes: (024), (026), and (048), all of which intersect with the whole-tone scale. The “triadic” family of trichords features two set classes: (036) and (037). The most complex family of trichords is the semitone family. The label “semitone” indicates that these set classes include ic1 in their pitch structure. The presence of ic1 in the semitone family of trichords makes them very attractive in jazz. The semitone family includes five set classes: (012), (013), (014), (015), and (016).

Figure 27.7 translates the integers from Figure 27.6 into pc sets (written in bold), analyzes the intervallic structure of each trichord, and shows inversionally related sets (written in square brackets).





HARMONIC POTENTIAL OF TRICHORDS




* * *



There are 12 transpositionally and inversionally related set classes. When transpositionally related trichords are the only consideration, the number of available trichords expands to 20, as shown in Figure 27.8. The top row compiles 12 transpositionally and inversionally related trichords; the top and bottom row combines 20 transpositionally related trichords.

This section demonstrates the harmonic interpretation of 20 pc-set complexes. A pc-set complex includes one of 20 transpositionally related trichords and demonstrates how it can function as rootless/incomplete and upper-structure formations. The resulting formations bridge the gap between upper-structure triads discussed in Chapter 14 and other three-note collections.





FIGURE 27.7 Families of Trichords: Pitch Notation





FIGURE 27.8 Transpositionally and Inversionally Related Trichords





“Diatonic” PC-Set Complexes


Figure 27.9 demonstrates four pc-set complexes—[025], [035], [027], and [057]—as complete and upper-structure formations. Since each trichord has two rotations, one can freely experiment with them to produce different chord voicings. In the forthcoming examples, accidentals apply only to the note to which they are attached and do not carry across the measure.

The number of chords that can use “diatonic” sets as upper structures is truly impressive. Because these sets are closely related to one another—[025] and [027] share two pitches in common—they often participate in similar harmonic environments. Frequently used as a quartal structure, [027] constitutes a neutral formation that participates in three pairs of dominant 7th chords, with each pair belonging to a different minor 3rd cycle. Rarely is such a pliable upper structure found. As mentioned before, [025], [035], [027], and [057]—and all the remaining trichords—are very effective as rootless formations. Making them work as such requires an understanding of their functionality. For instance, [025] in B♭Maj9 exhibits different characteristics than it does in A♭Maj13(♯11). In the former, [025] functions as a major 9th, a major 3rd, and a perfect 5th; in the latter, it functions as a major 3rd, a ♯11th, and a major 13th.





FIGURE 27.9 “Diatonic” PC-Set Complexes





Whole-Tone PC-Set Complexes


Figure 27.10 illustrates four pc-set complexes—[024], [026], [046], and [048]—as complete and upper-structure formations.

The whole-tone family of trichords shows an impressive collection of chords, particularly in the dominant 7th category. Since the whole-tone trichords are subsets of the whole-tone scale, the [024], [026], and [048] trichords participate in some form or another in every dominant 7th chord built on each scale degree of the corresponding whole-tone scale. The [046] trichord can even function as an upper structure in dominant 7th chords, which is derived from two different whole-tone scales, thus showing even greater harmonic flexibility.





FIGURE 27.10 Whole-Tone PC-Set Complexes





“Triadic” PC-Set Complexes


Figure 27.11 illustrates three pc-set complexes—[036], [037], and [047]—interpreted as complete and upper-structure formations.





FIGURE 27.11 “Triadic” PC-Set Complexes

In the case of [037]s and [047]s, you may have recognized the familiar upper-structure triads from Chapter 14. Here, however, the situation is reversed: a single “triadic” trichord functions as an upper structure of different dominant 7ths as opposed to a single dominant 7th supporting different upper-structure triads. By investigating how a single triad can support different chord types, their flexibility and function may be fully appreciated in jazz harmony.





Semitone PC-Set Complexes


Figure 27.12 demonstrates nine pc-set complexes—[012], [013], [023], [014], [034], [015], [045], [016], and [056]—analyzed as complete and upper-structure formations.

In the case of [012], which constitutes the most chromatic trichord, there are far fewer harmonic options than there are for the other types of semitone trichord. The [012] trichord can function as an embellishing formation that inflects different chords chromatically. Because of the highly chromatic nature that [012] projects, successful implementation of the trichord depends on the way it is articulated or orchestrated. With [013]s, so-called add note chords are introduced; they typically include notes that, under normal circumstances, are excluded from the structure of chords. The A♭Maj7(add4) chord, for instance, includes a perfect 4th, a note that is usually avoided in common jazz harmonic practice. The [045] trichord implemented as an upper structure of min7(♭5) chords has very interesting properties. Whereas in Dmin9(♭5), [045] functions in a traditional manner in Amin7(♭5), it creates a lot of chromatic tension and requires a resolution to more stable tones. Because of their unique intervallic structure, [016] and [056] are more fitting in the context of dominant 7th chords rather than other chords. In fact, [056] can occur in as many as ten different dominant 7ths. The pitch content of these dominant 7ths contains two “forbidden” notes: a perfect 4th and a major 7th.



FIGURE 27.12 Semitone PC-Set Complexes

In semitone (as well as other) pc-set complexes, conceptions of what constitutes consonance and dissonance are highly fluid, contextual, and subjective. Even though some of the chords do not sound syntactic in the tonal jazz sense, a Persichetti-esque caveat that “any note can sound simultaneously with any other note” can be invoked to justify the structure and sound of these formations.





MODAL POTENTIAL OF TRICHORDS




* * *



Figure 27.13 illustrates selections of trichords derived from the diatonic and chromatic modes. Not only do these trichords project the sound of the mode, they can also be horizontalized as motives and developed using different techniques of motivic transformations.



FIGURE 27.13 Trichords in Diatonic and Chromatic Modes





TRANSPOSITION AND INVERSION OF SETS




* * *



The [025] and its inverse [035] are related by T5I, which means that if you want to map the members of the first set on to the members of the second, a compound transformation called an inversion (TnI) must be used. The operation first inverts [025] around 0, and then transposes each member by +5. When using a mirror inversion you basically flip members of a pc set to the other side of the clock face. Pitch class 0 inverts on to itself; pc2 inverts on to pct; and pc5 inverts on to pc7. The inverted pitch classes are subsequently transposed clockwise by the so-called index number—5, in the present example—to arrive at [035]. Therefore, pc0 becomes pc5 of [035]; pct (inverted pc2) becomes pc3 of [035]; and pc7 (inverted pc5) becomes pc0 of [035]. Inversion is a compound operation that involves two steps: (1) the inversion around 0, and (2) clockwise transposition of the inverted set by a specific index number.

When comparing [025] and [035], notice the first member of [025] or pc0 maps on to the last member of [035] or pc5, the second member of [025] or pc2 maps on to the second member of [035], and the last member of [025] or pc5 maps on to the first member of [035]. These mappings are the consequence of mirror inversion. Given the two sets [025] and [035], or any pair of inversionally related sets, it is easy to determine the index number simply by figuring out the sum between integers of two sets: 0+5=5, 2+3=5, and 5+0=5. When comparing two inversionally related sets, the first member of the first set is added to the last member of the second, the second member to the second, and the third to the first.

Transposition (Tn) is a single-step operation that maps the first member of the set on to the first member of the second set, second to second, etc. When you compare two transpositionally related sets to determine the level of transposition or index number, subtract members of the first set from the members of the second. For instance, [247] and [t03] are members of (025) and are related by transposition. To calculate the level of transposition (index number), subtract 2 from t=8, 4 from 0=(‒4) 8, and 7 from 3=(‒4) 8. Notice that, in two instances, negative integers are obtained: 0‒4=‒4 and 3‒7=‒4. In these cases, apply the mod 12 operation that brings integers less than 0 and greater than 11 to the pitch-class space between 0 and e.





AURAL IDENTIFICATION OF TRICHORDS




* * *



Aural identification of pc sets helps to develop a more abstract way of hearing melodic and harmonic trichords. It removes them from the confines of tonality and places them in a tonally neutral environment without any recourse to familiar tonal traits (such as the role of the governing tonic or the referential sound of scale degrees with their functional implications). The prerequisite for pc-set recognition is the ability to identify intervals and interval classes. The correct recognition of interval classes within a pc set helps to figure out the normal form. This step rearranges unordered pitches and translates them into pitch classes. The next step is more abstract and involves translating normal forms to prime forms. As a practice routine, select a trichord and experiment with different pitch configurations of that trichord, which might include a transposition, reordering, and/or octave displacements, etc. You will be amazed at the number of possibilities and how different all these configurations sound.

In the online WORKBOOK, you are asked to identify melodic and harmonic trichords. Given the pitches C♯5, F4, E4, for instance, the following steps are recommended:

1.Identify interval classes between adjacent pitches. The interval class between the first and second pitch is ic4 and between the second and third pitch is ic1. Remember that you might hear the interval between C♯5 and F4 as a descending major 6th and between F4 and E4 as a descending minor 2nd. As ordered intervals they yield int4 and int11, but as unordered intervals (i.e. interval classes) they yield ic4 and ic1. We are interested in the latter.

2.Notate pitches: C♯5, F4, and E4 as integers: C♯5=pc1, F4=pc5, and E4=pc4.

3.With unordered pitch classes: pc1, pc5, and pc4, put them in ascending order: pc1, pc4, and pc5. That is the normal form [145], written in square brackets.

4.Based on the interval content of pc set [145], ic<31>, you can see that the set can be inverted and that the inversional partner is more intervallically packed, ic<13>.

5.Assign pc0 to the first pitch of the most packed arrangement (i.e. start at pc5 and move counterclockwise).

6.The prime form of a [145] is (014).

To expedite the process of pc-set recognition, locate the pitch classes on the clock face. You will immediately see that the counterclockwise arrangement of pitches counting from pc5 produces the prime form (014).

When played simultaneously, the pitches C♯5, F4, and E4 produce a certain harmonic sound that is unique to (014). Similarly, other set classes exhibit harmonic characteristics that are unique across the multitude of diverse pitch configurations that can occur within the boundaries of a particular set class. The ability to identify that unique sound greatly improves your ear and sharpens your overall harmonic sensitivity.
