Harmonic Highlights:

  • Prominent use of the bVII chord (Eb6, Bb7), often functioning as a ii-V to the bVII of F minor (Eb major).
  • Strong resolution to the relative major (Abmaj7) via an explicit Bbm7-Eb7-Abmaj7 ii-V-I progression.
  • Incorporation of altered dominant harmony, exemplified by the C7#9, for the V7 of the tonic minor.
  • Brief modulation through a Cm7-F7 progression, hinting at a V7/bVII movement.

Improvisation Focus: Targeting chord tones and navigating ii-V-I progressions across related key centers.

Difficulty Rating: 4. Requires navigating multiple minor and relative major key centers and understanding altered dominant harmony.
