Harmonic Highlights

  • Frequent deployment of altered minor ii-V progressions (e.g., Em7b5-A7b13, Dm7b5-G13b9) leads to various temporary tonicizations.
  • Prominent use of altered dominant chords (A7b13, G13b9) introduces significant chromatic tension and extended harmonic color.
  • A clear tonicization of the relative minor (Am) is established through the Fmaj7-E7-Am7 progression.
  • Dynamic shifts in ii-V chord qualities and target resolutions are evident, such as Em7b5-A7b13 (to Dm) followed by Dm7-G7 (to C).

Improvisation Focus Altered scale application over dominant chords.

Difficulty Rating 3 (Intermediate): Requires understanding of altered dominant scales and navigating complex minor ii-V progressions.
