Harmonic Highlights

  • Frequent use of I-vi-ii-V (F6-Dm7-Gm7-C7) cycles establishes a consistent diatonic framework in F major.
  • A ii-V cell (Cm7-F7) provides a clear tonicization of the subdominant (Bbmaj7) during the transition to the bridge.
  • Chromatic voice leading is achieved through the descending diminished connector (Am7-Ab°7-Gm7), a common substitute for the III-VI-ii-V turnaround.
  • The inclusion of the bVII7 (Eb7) functions as a backdoor dominant, adding non-diatonic color before returning to the tonic F6.

Improvisation Focus F Major Bebop scale (incorporating the chromatic passing tone between the 5th and 6th) to navigate the frequent ii-V-I turnarounds.

Difficulty Rating 2/5: The progression’s reliance on standard diatonic patterns and predictable modulations makes it highly accessible for intermediate improvisers.
