No obvious ii-V patterns detected.
- Distinctive D9-Fm6 vamp creates a non-diatonic oscillation between a V7/G and the bIII minor 6, establishing modal ambiguity.
- Rapid descending chromatic dominant sequence (B7-Bb7-A7) generates tension through successive secondary dominants before resolving to V/F.
- Extended V7 progressions (D7-G7) function as a V/G to V/C chain, providing strong forward motion and cyclic harmonic movement.
Improvisation Focus: Dominant 7th arpeggios and altered scales.
Difficulty Rating: 5 (Advanced) due to the rapid, non-diatonic harmonic shifts and the need to navigate complex altered dominant chord changes.
