Harmonic Highlights:
- Establishes F major through a standard ii-V-I (Gm7-C7-Fmaj7).
- Features a prominent modulation to Ab major via Bbm7-Eb7b9-Abmaj7, followed by Dbmaj7.
- Includes another clear modulation to Bb major with Cm7-F7-Bbmaj7 progressions.
- Utilizes a secondary dominant (D7b9) functioning as a V/ii leading to Gm7.
Improvisation Focus: Navigating the successive key center modulations (F, Ab, Bb).
Difficulty Rating: 3 (Intermediate) Requires a solid understanding and execution of melodic and harmonic approaches across multiple key changes.
