Harmonic Highlights:
- The E7#5 (V/vi) resolving to Amaj7 (VImaj7) showcases an altered dominant tension with modal interchange.
- C7 (V/IV) extends the tonic’s dominant function before resolving to Fmaj7, adding color and drive.
- A prominent chromatic side-slip occurs with Ebm7-Ab7 (ii-V of Db) directly leading into Dm7-G7 (ii-V of C).
Improvisation Focus: Altered Dominant Scale
Difficulty Rating: 4/5. The frequent use of altered dominants, chromatic ii-V movements, and modal interchange requires advanced harmonic understanding.
