Harmonic Highlights

  • Employs a minor line cliché (Dm–Dmb6–Dm6–Dm7), utilizing chromatic internal voice leading over a static D minor tonic.
  • Incorporates a ii-V interpolation (Cm7–F7) that functions as a secondary tonicization of the IV chord (Bbmaj7).
  • Features a dense chromatic turnaround (B7#5#9 to Bb7#11 to A7#5#9) creating high-tension dominant substitutions that resolve to the tonic.

Improvisation Focus D Melodic Minor to navigate the shifting 6th and 7th degrees and the specific altered dominant tensions.

Difficulty Rating 4/5. The fast 3/4 feel and rapid-fire altered dominants require advanced modal fluency and precise navigation of non-diatonic changes.
