Harmonic Highlights:
- Initial progression immediately targets Fm (iiø-V7b9-i), a minor subdominant relative to C minor, setting a darker, bebop tone.
- Frequent minor iiø-V7b9 progressions (Dm7b5-G7b9) are interspersed with unexpected major key tonicizations (Cmaj7, Bbmaj7).
- Features a chromatic dominant Ab7 leading to G7 (V of C), adding a sophisticated harmonic detour before returning to the main cycle.
- Employs altered dominant chords (C7b9, G7b9) throughout, characteristic of bebop harmony.
Improvisation Focus:
- Navigating Melodic Minor modes and their derivatives over the various minor and altered dominant chords.
Difficulty Rating:
- 5 (Advanced). Requires sophisticated understanding of minor harmony, multiple modulations, and altered dominant scales for effective improvisation.
