Harmonic Highlights:
- Rapid modulations are prevalent, driven by sequential ii-V progressions that resolve to G major (Am7-D7-Gmaj7) and F major (Gm7-C7-Fmaj7).
- Features a tritone substitution dominant (A7b5) following Em7, creating an altered sound that resolves deceptively to Abmaj7 (IV).
- Incorporates a minor iv - bVII progression (Abm7-Db7), adding a characteristic “backdoor” dominant flavor or a temporary tonicization.
Improvisation Focus: Adaptive chord-scale navigation over sequential ii-V changes.
Difficulty Rating: 4/5. The numerous, quick modulations and non-diatonic alterations demand advanced harmonic understanding and improvisational agility.
