- The use of chromatic passing diminished chords (B°7, C#°7) creates a smooth stepwise bass movement between the Bb6, Cm7, and Bb/D landmarks.
- The inclusion of Ab7#11 functions as a tritone substitution for D7 (V7/vi), providing a chromatic approach to the G9 secondary dominant.
- A secondary ii-V (Am7b5 - D7b9) marks a brief functional modulation to the relative minor (Gm), contrasting the bright tonic major sections.
- Rapid turnaround cycles (G7b13 - Cm7 - F7) utilize altered extensions to facilitate sophisticated voice leading back to the tonic.
Improvisation Focus The Bb Major Bebop scale, as it provides the necessary chromatic passing tones to fluidly connect the frequent diminished and secondary dominant substitutions.
Difficulty Rating 3/5: The fast harmonic rhythm and frequent chromatic transitions demand precise linear navigation and a solid grasp of non-diatonic voice leading.
