Harmonic Highlights

  • Frequent interplay between Fmaj7 (relative major) and Dm7 (tonic minor) establishes a rich modal ambiguity.
  • Prominent Em7b5-A7 progressions firmly resolve to Dm7, characteristic of minor key ii-V-i cadences.
  • Chromatic alterations like Db7 (bII7 of C) and the descending minor sequence Am7-Abm7-Gm7 introduce unexpected color and movement.
  • A significant, late-occurring modulation with Amaj7, A#07, and Bm7-E7 (a ii-V to A major) creates strong temporary tonicizations.

Improvisation Focus Navigating minor ii-V-i progressions and their chromatic extensions.

Difficulty Rating 4 (Advanced). Frequent chromaticism and non-diatonic modulations, especially in the B section, demand advanced harmonic understanding.
