Harmonic Highlights:

  • Employs frequent minor ii-V-i progressions (e.g., Fm7b5-Bb7#9 to Ebm) as a core harmonic device.
  • Features extensive use of altered dominant chords (e.g., D7#9, C7#9, Bb7#5) to create sophisticated tension and resolution.
  • Incorporates fully diminished chords (C07) and chromatic dominant cycles (e.g., Ab7-Db7-Gb7-B7) for harmonic color and unexpected voice leading.

Improvisation Focus: Melodic Minor scale and its modes (especially Altered/Super Locrian).

Difficulty Rating: 4 (Advanced Intermediate). The rapid, non-diatonic chord changes and frequent altered dominants require a deep understanding of advanced harmony.
