Harmonic Highlights:

  • Features frequent ii-V-I progressions, often departing from the F minor key center, including a brief ii-V-I in Ab major (Bbm7-Eb7#5-Abmaj7).
  • Employs a signature, extended sequence of descending major ii-V-I cycles (e.g., C#m7-F#7-Bmaj7 through Dm7-G7-Cmaj7).
  • Incorporates blues-inflected V/iv movements (F7 to Bbm7) and passing diminished chords (C#07) for harmonic tension.

Improvisation Focus: Navigating rapid, sequential ii-V-I changes across multiple, quickly shifting key centers.

Difficulty Rating: 4 (Advanced Intermediate). The constant, fast-moving harmonic rhythm and frequent key changes demand strong harmonic recall and dexterity.
