Harmonic Highlights

  • Dominant Prolongation: The A-section features a prolonged ii-V cell (Gm7–C7) that delays resolution to the tonic F6, creating a repetitive, “vamping” harmonic tension characteristic of swing-era standards.
  • Secondary Dominant Cycling: The bridge utilizes a V7/V (G7) to V7 (C7) progression, employing a circle-of-fifths movement that provides a clear directional drive back to the primary key.
  • Subdominant Shift: The transition to Bb6 (IV) via F7 (V7/IV) introduces blues-inflected subdominant coloring, common in “rhythm changes” variations.

Improvisation Focus F Major Bebop Scale.

Difficulty Rating 2/5 — The predictable AABA structure and repetitive ii-V sequences make it an ideal vehicle for mastering basic swing phrasing and voice leading.
