Harmonic Highlights

  • The A section utilizes a characteristic stepwise diatonic motion (I–ii–iii–IV), creating a smooth, linear bass movement typical of early swing ballads.
  • The bridge features a sudden modulation to the bVI key area via a repeated ii-V sequence (Ebm7–Ab7), providing a dark, subdominant minor contrast to the F major tonic.
  • Harmonic stability is maintained through standard ii-V-I cadences (Gm7–C7–F6) that resolve the chromaticism of the bridge back to the home key.

Improvisation Focus F Major Diatonicism for the A sections, shifting to Ab Mixolydian to navigate the bridge’s temporary modulation.

Difficulty Rating 2/5; the song is largely diatonic and usually performed at a slow tempo, requiring only basic proficiency in navigating one significant key center shift.
