Harmonic Highlights

  • Frequent diatonic ii-V-I progressions (Gm7-C7 to Fmaj7) firmly establish and reinforce the F major key center.
  • The Bbm7-Eb7 sequence functions as a backdoor dominant (ii-V of Ab, resolving to F), providing an effective bVII7-I movement.
  • Chromatic voice leading is evident in the Am7-Abm7-Gm7 descent, creating smooth tension before the subsequent ii-V.
  • The Abmaj7 chord (bIIImaj7) introduces modal interchange, temporarily borrowing from F minor before resolving to the ii-V.

Improvisation Focus Precise Chord-Scale Navigation.

Difficulty Rating 4 (Advanced). Its incorporation of backdoor dominants, chromatic voice leading, and modal interchange requires advanced harmonic understanding and agile improvisation.
