Harmonic Highlights

  • The A section utilizes a relentless I-vi-ii-V cyclical progression (F6-Dm7-Gm7-C7), a hallmark of “rhythm changes” style diatonic harmony.
  • Transitions to the bridge are facilitated by secondary dominants, specifically A7 acting as $V/vi$ to lead into the relative minor (D minor) and subdominant (Bb major) areas.
  • The bridge employs a tonal shift to G major via a ii-V-I sequence (Am7-D7-Gmaj7) before utilizing a Gm7-C7 turnaround to return to the home key of F major.

Improvisation Focus F Major Bebop Scale (utilizing the chromatic passing tone between the 5th and 6th degrees).

Difficulty Rating 2/5: The predictable harmonic rhythm and standard ii-V-I patterns make it highly accessible for intermediate improvisers practicing guide-tone connectivity.
