Harmonic Highlights:
- Dominant use of bII7sus-bII7 and bVII7sus-bVII7 progressions, often functioning as tritone substitutes and blues dominants within a G# minor context.
- Frequent descending whole-step dominant movements (e.g., Ab7 to Gb7), creating a characteristic fusion sound and implying a cycle of modal dominants.
- Chromatic alterations (G7, B7, Db7) introduce momentary shifts in tonal gravity, moving beyond simple diatonicism and enhancing harmonic unpredictability.
Improvisation Focus: Mixolydian mode with strong blues inflections.
Difficulty Rating: 4 (Advanced-Intermediate) โ The harmonic ambiguity from constant dominant tension and chromaticism requires sophisticated melodic and rhythmic navigation.
