Harmonic Highlights

  • Employs interlocking minor ii-V progressions, specifically utilizing a ii-V of iv (Cm7 to D7b9) to transition from D minor to G minor.
  • Features descending diatonic and chromatic bass lines (Cm7/Bb, Gm7/F) to provide linear smooth motion through minor functional harmony.
  • Utilizes a distinctive turnaround (Bm7b5 to Em7b5 to A7b9) that functions as a chromatic/sequential approach to the primary dominant.

Improvisation Focus Minor ii-V-i vocabulary and D harmonic minor.

Difficulty Rating 3/5: Requires navigating frequent minor-key modulations and managing altered dominant tensions within a traditional bebop framework.
