Harmonic Highlights

  • Prolonged tonicization of D minor via static Dm7 vamps and A7#9 dominant connectors.
  • A minor ii-V-i progression (Am7b5 โ€“ D7b9 โ€“ Gm7) targeting the subdominant area.
  • Functional modulation from the D minor tonality to a parallel F Major ii-V-I (Gm7 โ€“ C7 โ€“ Fmaj7).
  • Cyclic reliance on minor-key turnarounds (Em7b5 โ€“ A7b9 โ€“ Dm7) to reinforce the dark, modal character.

Improvisation Focus D Melodic Minor for navigating both tonic minor stability and altered dominant tensions.

Difficulty Rating 3/5; while the changes are functionally standard, the frequent shifts between parallel major and minor centers at high tempos require significant harmonic agility.
