- The sequence bVIImaj7 - bIImaj7 - V7 (Dbmaj7 - Bmaj7 - Bb7) provides a striking chromatic approach to the dominant, characteristic of post-bop harmony.
- Upper structure triads over an Eb pedal point (E/Eb, D/Eb) create sophisticated modal colors and harmonic ambiguity.
- The inclusion of a minor ii-V-i (Dm7b5 - G7#9 - Cm7) temporarily tonicizes the relative minor with a strong altered dominant.
Improvisation Focus: Melodic Minor modes, particularly the Altered Scale and Lydian Augmented, for navigating the sophisticated chromatic and altered sonorities.
Difficulty Rating: 4 (Advanced). The frequent chromaticism, pedal point upper structures, and altered dominants require a deep understanding of advanced harmonic concepts.
