Harmonic Highlights:
- Establishes F major through recurring II-V-I progressions (Gm7-C7-Fmaj7).
- Employs D7 as a consistent secondary dominant (V/ii) to cycle back to Gm7.
- Features a direct, abrupt modulation to Ab major via a Bbm7-Eb7-Abmaj7 (II-V-I) progression.
- Includes an Am7-D7 sequence, functioning as a II-V leading to the ii chord (Gm7), briefly tonicizing the supertonic.
Improvisation Focus: Navigating II-V-I progressions across changing tonalities.
Difficulty Rating: 4 (Challenging) - The abrupt modulation to Ab major requires significant harmonic awareness and quick melodic adaptation.
