Harmonic Highlights

  • The use of a #I°7 (F#°7) passing chord provides a chromatic bridge between the tonic (Fmaj7) and the supertonic (Gm7), typical of swing-era voice leading.
  • The progression employs a backdoor dominant resolution (Eb7 to Am7), utilizing the bVII7 chord to reach the iii chord via parallel motion.
  • A direct modulation occurs via a ii-V-I sequence (Am7–D7–Gmaj7), shifting the tonal center from F Major up a whole step to G Major.

Improvisation Focus

Diatonic guide-tone navigation focusing on the 3rds and 7ths to highlight the frequent ii-V-I transitions.

Difficulty Rating

2/5. The harmonic rhythm is predictable and the modulations follow standard functional patterns, making it accessible for those familiar with basic jazz vocabulary.
