Harmonic Highlights:
- Features a clear ii-V-I progression in F major (Gm7-C7-Fmaj7), reinforcing the tonic.
- Incorporates a secondary dominant (D7) functioning as V/ii, creating a temporary pull to Gm7.
- Employs a distinct backdoor ii-V-I progression (Bbm7-Eb7-Fmaj7), adding a sophisticated modal interchange color.
- Utilizes Ab07 as a passing diminished chord, building chromatic tension before resolving to Gm7.
Improvisation Focus: F Major scale and its associated modes, adapting to the secondary and backdoor dominant functions.
Difficulty Rating: 4 (Advanced Intermediate). The blend of standard ii-V-I, secondary dominants, passing diminished, and a backdoor ii-V requires a solid understanding of functional harmony and modal improvisation.
