Harmonic Highlights:
- Frequent secondary dominant function, exemplified by D7 (V7/ii) leading to Gm7.
- Temporary tonicization of the subdominant (Bbmaj7) via a ii-V progression (Cm7-F7).
- Extended descending cycle of dominant 7ths (A7#5-D9-G7#5-C9) building strong forward motion towards the tonic.
- Incorporation of iv minor to bVII7 (Bbm7-Eb7), offering a ‘backdoor’ dominant flavor or parallel minor exploration.
Improvisation Focus: Mixolydian scales and their common alterations (e.g., altered, Lydian dominant) to navigate the prevalent V7 chords.
Difficulty Rating: 4. The rapid harmonic rhythm, extensive dominant cycles, and frequent altered chord extensions demand an advanced understanding of improvisation.
