Harmonic Highlights:

  • Frequent use of V/ii (D7) moving to Gm7 creates strong functional forward motion toward the F major tonic.
  • A “backdoor” ii-V progression (Bbm7-Eb7) effectively transitions from the IV chord (Bbmaj7) back toward the home key.
  • The structure employs an extended cycle of fourths using dominant chords (A7-D9-G7-C9), demanding precise resolution targeting.
  • Parallelism and sudden ii-V shifts (Cm7-F7) facilitate brief tonicizations of the subdominant (Bb).

Improvisation Focus: Guide tone navigation through the rapid cycle of fourths and dominant chains.

Difficulty Rating: 3/5. The harmonic rhythm accelerates significantly during the turnarounds, requiring fluid transition between dominant scales at typically bright tempos.
