Harmonic Highlights

  • The #I°7 (F#°7) functions as a chromatic passing chord connecting the tonic (Fmaj7) to the supertonic (Gm7), creating a smooth ascending bass movement common in early jazz ballads.
  • Frequent ii-V-I cycles tonicizing the subdominant (Cm7-F7-Bbmaj7) shift the tonal center temporarily to IV, providing a soulful, gospel-influenced lift.
  • The transition from IVmaj7 to ivm7 (Bbmaj7 to Bbm7) employs modal interchange from F minor, introducing a poignant “darkening” effect before resolving back to the tonic.
  • Secondary dominants, specifically the VI7 (D7) acting as a V/ii, facilitate a strong harmonic pull into the recurring Gm7-C7 turnaround.

Improvisation Focus F Major Bebop Scale.

Difficulty Rating 2/5: The progression consists of foundational jazz cliches and predictable resolutions, making it highly accessible for intermediate soloists to practice melodic phrasing.
