Harmonic Highlights

  • The progression features a sophisticated I–iii–VI–ii–V turnaround, using the D7#9 as a secondary dominant (V/ii) to create tension before resolving to Gm7.
  • Extensive ii–V7 oscillations (Gm7–C7) establish a strong cadential flow, characteristic of the “patter” style of the A-section.
  • Tonal stability is maintained through frequent returns to Fmaj7 and F6, providing a clear diatonic anchor despite the secondary dominant alterations.

Improvisation Focus F Major Bebop scale (F, G, A, Bb, C, C#, D, E) to emphasize chord tones on downbeats while navigating the frequent ii–V cycles.

Difficulty Rating 2/5: The changes are largely diatonic and predictable, making it an ideal study for mastering secondary dominants and standard ii-V resolutions.
