- Frequent use of altered dominant chords (C7b13, C7b9, D7b9) creating tension and implying specific voice leading resolutions.
- Clear tonicization of the iii minor chord (Gm7) via a iiø7-V7 progression (Am7b5-D7b9).
- Repetitive ii-V movements (Fm7-Bb7) reinforce the Eb major key center, often preceded by secondary dominant functions (e.g., C7 to Fm7).
Improvisation Focus: Altered Dominant scales over V7 chords.
Difficulty Rating: 4 (Intermediate-Advanced). The numerous altered dominant chords and secondary tonicizations require a solid grasp of complex harmonic substitution and modal application.
