Harmonic Highlights:

  • Employs a standard ii-V-i progression in D minor (Gm6, A7#9, Dm7) as a primary harmonic movement.
  • Features a chromatic passing dominant (Db7) that sets up a ii-V-I modulation to Bb major (bVI of D minor).
  • Utilizes the maj7#11 chord (Bbmaj7#11), suggesting a Lydian quality within the bVI section.
  • Incorporates a temporary tonicization of A minor (v) via its V7 chord (E7b13 leading to Am7).

Improvisation Focus: Navigating the D Dorian mode as a foundation, while adapting to temporary modulations like Bb Lydian.

Difficulty Rating: 4 (Advanced Intermediate). Its slow tempo belies a complex harmonic progression with multiple temporary modulations and chromatic passing chords, requiring precise melodic contouring.
