Harmonic Highlights:
- Prominent use of minor iiø7-V7b9-iMaj7 progressions, particularly the opening Gm7b5-C7b9-Fm/maj7, establishing a bittersweet minor tonic.
- Frequent and rapid tonicizations to C major (Dm7b5-G7b9-Cmaj7) and Bb major (Cm7-F7b9-Bbmaj7) sequences, creating constant harmonic motion.
- Strategic use of altered dominants (e.g., C7b9, G7b9) and tritone substitution (Ab7b9 for D7b9) enhances tension and chromatic resolution.
Improvisation Focus: Precise chord-scale application using altered scales for V7b9 chords and melodic minor for minor tonics across frequent modulations.
Difficulty Rating: 4 (Advanced Intermediate). This standard demands fluid improvisation over rapidly shifting key centers and a high comfort level with altered dominant and minor major 7 sonorities.
