Harmonic Highlights:
- Features a striking descending chromatic minor chord sequence (G#m7, Gm7, F#m7), creating unique voice leading.
- Employs multiple rapid ii-V-I modulations, notably to Ab major (Bbm7-Eb7-Abmaj7) and Bb major (Cm7b5-F7-Bbmaj7), moving through non-adjacent key centers.
- Utilizes various altered dominant chords such as C7#5, F7b9#5, Eb7b9, and A7b13, adding significant harmonic tension and color.
Improvisation Focus: Navigating altered dominant scales (e.g., Altered Scale, Lydian Dominant) for the frequent V7#5, V7b9#5, and V7b13 chords.
Difficulty Rating: 5 (Advanced) – The frequent, often non-diatonic modulations and complex altered dominants demand highly sophisticated harmonic understanding and execution.
