Harmonic Highlights:
- Features frequent minor ii-V progressions, often targeting non-tonic scale degrees (e.g., Am7b5-D7b13 leading towards Gm).
- Employs a striking chromatic dominant movement (F7-B7-Bb7), showcasing a tritone substitution (B7 for F7) before the tonic dominant.
- Utilizes a characteristic minor plagal cadence with the recurring Abm6 resolving to Ebmaj7, adding a sophisticated melancholic color.
Improvisation Focus: Navigating altered dominant harmony.
Difficulty Rating: 4 (Advanced Intermediate) because it demands fluent navigation of numerous non-diatonic ii-V progressions, altered dominants, and chromatic substitutions.
