Harmonic Highlights

  • Utilizes standard ii-V-I cadences (Cm7–F7–Bb6) and iii-VI-ii-V turnarounds throughout the A sections.
  • The bridge features a sequential “circle of fourths” chain of dominant 7th chords (III7–VI7–II7–V7), specifically D7–G7–C7–F7.
  • Relies on secondary dominants to create functional tension that resolves predictably back to the Bb major tonic.

Improvisation Focus Chord-tone arpeggiation to navigate the cycling dominant 7th chords in the bridge.

Difficulty Rating 2/5 — The progression follows highly predictable swing-era formulas and standard diatonic resolutions, making it an ideal entry point for learning functional jazz harmony.
