Harmonic Highlights:
- Frequent tonicization of the vi minor chord (
Cm7 - G7b9) establishing a clear V/vi secondary dominant function. - Characteristic chromatic minor chord descent (
Cm7 - Bm7 - Bbm7) preceding a ii-V-I progression to the IV chord (Abmaj7). - Inclusion of
Dbmaj7#11(bVImaj7#11), introducing a Lydian color, often acting as a pre-V or backdoor dominant substitute.
Improvisation Focus: Arpeggio Superimposition.
Difficulty Rating: 3 (Intermediate). The blend of diatonic functions with chromatic descents and modal interchange requires precise melodic navigation.
