Harmonic Highlights:
- Employs frequent minor ii-V-i progressions (e.g., Fm7b5-Bb7#9 to Ebm) as a core harmonic device.
- Features extensive use of altered dominant chords (e.g., D7#9, C7#9, Bb7#5) to create sophisticated tension and resolution.
- Incorporates fully diminished chords (C07) and chromatic dominant cycles (e.g., Ab7-Db7-Gb7-B7) for harmonic color and unexpected voice leading.
Improvisation Focus: Melodic Minor scale and its modes (especially Altered/Super Locrian).
Difficulty Rating: 4 (Advanced Intermediate). The rapid, non-diatonic chord changes and frequent altered dominants require a deep understanding of advanced harmony.
