My exercise ‘Jody, Donna, Four Brothers and Koko’ is the second in a series of exercises including licks from ‘Donna Lee’ (the first, ‘Midnight Donna and Reets in Paris’ is in an earlier post.) Besides ‘Donna Lee’, other sources I used for this exercise include Horace Silver’s The Jody Grind, Jimmy Giuffre’s Four Brothers, and Charlie Parker’s ‘Koko’ (one of his solos on the changes to ‘Cherokee’.) My intent is to show how the voicings for dominant chords most commonly used by jazz pianists – i.e. those built ‘off the third’ or ‘off the seventh’ – are equally useful as both melodic fragments and as harmonic structures. The exercise uses a harmonic rhythm of one chord per bar; although this is not the harmonic rhythm seen in the uses of the dominant cycle mentioned above, it is the harmonic rhythm in the first two bars of ‘jazz blues‘ progressions such as ‘Billie’s Bounce‘ and ‘Tenor Madness’.
Practicing this exercise will make more sense if you first practice a one bar pattern of seventh scales ascending or descending in eighth notes (i.e. seven up or seven down only) around the circle of ascending fifths/descending fourths in the RH with three note rootless voicings for dominant chords in the LH as shown in Degreg p. 87:
I would then suggest practicing the rootless voicings doubled in both hands (i.e. LH plays treble clef voicings from p. 87 while RH doubles an octave above.) Once you can play doubled voicings at a moderate, steady tempo, you should be ready to move on to the ‘parallel patterns‘ exercise, where the RH plays patterns derived from the voicings that the LH is playing simultaneously. Below the parallel patterns exercises I have shown the ways that the two patterns can be combined contrapuntally. Below the exercise are some reflections on the circle of descending fifths, both in music history as a whole and in jazz tunes.
When the first keyboard instruments with a twelve-note chromatic scale were introduced around the beginning of the 14th century, they entered a world where years had twelve months and days were measured with a twelve-hour clock. In addition to the number twelve being an important unit of measurement in this era, it also figured prominently in two major wisdom traditions: the Christian tradition, founded on the Gospels and their stories of Jesus’ twelve apostles, and the Zodiac signs, which divide the year up into twelve periods, each named after a different animal or mythical figure and each aligned with a constellation of stars or a planetary movement. The recurrence of the number twelve in so many foundations of Western culture (including the twelve-bar blues) suggests that while it may occur naturally in some kinds of measurements, scientific, artistic and religious thinkers have also deliberately or subconsciously chosen it in some cases for its association with beauty, symmetry, and truth.
I believe an association between twelve and the pursuit of harmonic symmetry can be heard in C.P.E. Bach’s Solfeggietto, composed at a time in the 18th century when a debate was still raging between different approaches to tuning keyboard instruments. The approaches to tuning that were prevalent at the time (such as ‘mean-tone temperament’) rendered some intervals and key signatures more consonant and others more dissonant, while a newer approach called ‘equal temperament’ allowed composers greater freedom to modulate through multiple keys within a single piece. In Temperament: How Music Became a Battleground For the Great Minds of Western Civilization, Stuart Isacoff writes that C.P.E. Bach ‘wanted equal temperament but was confused about how to get it.’ The conclusion of Solfeggietto uses all twelve tones of the chromatic scale in the space of four measures, through a progression of five dominant seventh chords sequenced through the circle of descending fifths followed by a diminished seventh chord. This passage, which may have tested the limits of a tuning where not all major keys were equally consonant, suggests that Bach’s interest in equal temperament may have been related to an interest in using wide-ranging modulations in his compositions. C.P.E. Bach’s progressions and melodic shapes, and their relationship to the pop song structures on which bop players based their improvisations and compositions, caught the ear of Bud Powell, who made ‘Solfeggietto‘ the introduction to his remarkable hybrid piece Bud on Bach. The dominant cycle can also be heard in the Mazurka in G Minor Op. 67, No. 2 by Chopin. Among the bop players who used Chopin’s melodic ideas in their improvising was Charlie Parker, whose use of the Military Polonaise and the Minute Waltz is documented on a fascinating webpage devoted to Bird’s use of quotes.
In many jazz standards from the swing and bop eras, dominant seventh chords moving through the circle of fifths are used in extended harmonic rhythms. The bridges of ‘Stompin’ At the Savoy’ and ‘I Got Rhythm’ move through a four-chord sequence along the circle of fifths, spending two measures on each chord. and the first half of the progression in ‘Sweet Georgia Brown’ moves through a three-chord sequence in the dominant cycle, spending four measures on each chord before resolving to the I chord. In addition to being often-played jazz standards, the chord progressions of these tunes have been used as the basis for many jazz compositions: Charlie Parker based his ‘Relaxin’ With Lee’ on ‘Stompin’, and was one of many jazz players to base multiple tunes, including his ‘Anthropology (a.k.a. Thrivin’ On A Riff)’ on the chord progression from ‘I Got Rhythm’. Monk’s ‘Bright Mississippi’, J.J. Johnson’s ‘Teapot’ and Jackie McLean’s ‘Dig’ are based on ‘Sweet Georgia Brown’.
In contrast to the relatively expansive use that Tin Pan Alley and swing-era composers made of the dominant cycle, composers in the bop era and afterwards used dominant cycles with a more accelerated harmonic rhythm (two beats per change) to reharmonize standard progressions; Thelonious Monk’s ‘Humph’ is a dominant cycle reharmonization of ‘I Got Rhythm’; and the heads of Barry Harris’ ‘Save Some For Later’ and Benny Golson’s ‘Blues March’ use the dominant cycle to reharmonize different phrases of the twelve bar blues progression. Monk’s tune ‘Skippy‘ is based on his dominant cycle reharmonization of ‘Tea for Two’ (although the ‘Tea for Two’ reharm was not recorded until a number of years after ‘Skippy’).
Jazz composers also have used the dominant cycle as a building block of new progressions, rather than just as a means of reharmonizing existing ones. Duke Ellington and Billy Strayhorn deftly interpolated the dominant cycle into a number of ballads, using the tritone substitution on ‘Prelude to A Kiss‘ and using altered dominants on ‘A Flower Is A Lovesome Thing’, and Duke Jordan based the bridge of his tune ‘Jordu’ on the dominant cycle. (Two lesser known tunes, John Lewis‘ ‘Three Windows‘ and Vince Guaraldi’s ‘Like A Mighty Rose’, also make interesting use of the dominant cycle in their bridges.) Dominant 7th chords moving through the circle of descending fifths also are used in Blossom Dearie’s intro to her version of ‘I Hear Music’ (which moves all the way around the circle). McCoy Tyner’s ending to ‘The Days of Wine and Roses‘ and Hank Jones‘ ending to ‘When There is Love‘ (from his album of the same name with Abbey Lincoln) move halfway around the circle. (Cycles of this type have also found their way into a number of keyboard-driven rock tunes. In The Doors’ tune ‘Light My Fire‘, Ray Manzarek’s intro includes a sequence of major chords moving around the circle of fifths and far afield of the tonic key of the chorus (D) . In some live versions of his tune ‘Such A Night’, Dr. John includes a dominant cycle in his solo piano break.)
As always, I welcome all kinds of comments on this blog entry, but I would be particularly interested in hearing about other culturally significant uses of the number twelve, or in other examples of pieces that include dominant-cycle modulation. I encourage musicians reading this to try composing a twelve-bar blues melody following the Barry Harris scale outline discussed in an earlier post and incorporating some of the dominant seventh chord patterns from this post.
