Harmonic Highlights:
- Prominent use of the half-step chromatic shift, exemplified by the Cm7 to Bmaj7#11 progression, creating a bright Lydian sound directly following a diatonic ii chord.
- Extensive application of dominant 7 sus chords (Bb7sus, A7sus, F#7sus, Eb7sus, C7sus), indicating a preference for open, ambiguous harmony over traditional V7 resolutions.
- Non-functional descending sus chord sequence (A7sus, F#7sus, Eb7sus, C7sus), demanding adaptability to rapid, often tritone-related harmonic shifts.
Improvisation Focus: Chord-scale improvisation with an emphasis on Lydian and Mixolydian modalities over rapidly changing chromatic centers.
Difficulty Rating: 5 (Advanced). Its non-functional harmony, frequent modulations, and use of extended chord voicings challenge traditional improvisational approaches.
