Harmonic Highlights

  • Starts on the subdominant (IVmaj7), delaying tonic resolution to create an expansive, “wide” melodic feel.
  • Employs a comprehensive circle-of-fifths sequence (iii-VI-ii-V-I) that drives the primary harmonic motion toward Ab major.
  • Utilizes a G7b9 as a secondary dominant (V/iii), introducing harmonic tension that resolves to the mediant minor (Cm7).
  • Frequent ii-V7/IV (Ebm7-Ab7) interpolations facilitate smooth transitions back to the subdominant.

Improvisation Focus Ab Major Scale and its related modes (Dorian and Mixolydian) to navigate the dense ii-V-I progressions.

Difficulty Rating 2/5 - The piece relies on highly predictable functional harmony and standard jazz cycles, making it an ideal study for intermediate players.
