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.
