Harmonic Highlights:
- Frequent tonicization of the IV chord (Abmaj7) through characteristic ii-V-I progressions (Bbm7-Eb7-Abmaj7).
- Prominent “backdoor” ii-V progression (Abm7-Db7) resolving directly to the tonic Ebmaj7, adding sophisticated color.
- Employs a descending sequence of ii-V changes (e.g., Am7-D7, Gm7-C7) creating fluid, often modulating, harmonic movement away from the tonic.
Improvisation Focus: Arpeggios and guide tones over ii-V-I progressions.
Difficulty Rating: 4 (Advanced Intermediate). The blend of standard ii-V-I movements with less common “backdoor” resolutions and descending ii-V cycles requires significant harmonic understanding.
