Harmonic Highlights

  • The progression employs a #io7 (F#o7) passing chord to provide chromatic bass movement (Fโ€“F#โ€“G) between the Imaj7 and iim7.
  • The bridge initiates a temporary modulation to the subdominant (IV) using a secondary ii-V (Cm7โ€“F7) leading to Bbmaj7.
  • The Eb7 in the bridge acts as a bVII7 (backdoor dominant), creating a smooth chromatic transition toward the Am7 (III) through a cycle-of-fifths sequence.
  • Standard III-VI-II-V turnarounds (Am7โ€“D7โ€“Gm7โ€“C7) reinforce the F major tonality while providing harmonic motion through the circle of fourths.

Improvisation Focus Functional voice leading through guide tones (3rds and 7ths) to highlight chromatic transitions and secondary dominant resolutions.

Difficulty Rating 2/5; the structure relies on standard functional cycles and common jazz tropes, making it highly accessible for intermediate soloists.
