Harmonic Highlights:

  • Strong emphasis on the relative major (Fmaj7 as bIIImaj7), often treated as a temporary tonic throughout the form.
  • Chromatic dominant F7 (V7/bVI) leads to Bbmaj7 (the bVImaj7 chord in D minor), adding a distinct major-key dominant function.
  • Rich minor tonic variations (Dm, Dm/maj7, Dm7, Dm6) at the final cadence showcase different minor scale influences on the tonic.
  • Secondary dominant E7 (V7/Am7) briefly resolves to the minor dominant (v), adding chromatic tension and a short detour.

Improvisation Focus: Navigating the interplay between D natural minor (F major) and D harmonic minor scales.

Difficulty Rating: 3. The frequent shifts between D minor and its relative major F, combined with secondary dominants and various minor tonic qualities, require intermediate harmonic understanding.
