Harmonic Highlights:
- Extensive use of II-V-I progressions, notably tonicizing F major (Gm7-C7-Fmaj7).
- Frequent employment of dominant 7b9 chords (D7b9, C7b9, E7b9), creating strong harmonic tension and implying altered dominant scales.
- Sequential II-V movements (e.g., Am7-D7b9 to G, Bm7-E7b9 to Am) drive the progression through multiple transient key areas.
Improvisation Focus: Bebop Scales
Difficulty Rating: 5 (Advanced) – Requires mastery of rapid II-V-I changes, altered dominant scales, and navigating quick transient modulations characteristic of bebop.
