Harmonic Highlights:
- Initial sections firmly establish F major through recurring Imaj7 and ii-V progressions.
- Significant tonicization of A minor is introduced, departing from the initial F major key center.
- Heavy reliance on the minor iiø-V7(b9)-i progression (Bm7b5-E7b9-Am7) extensively reinforces the A minor tonality.
Improvisation Focus: Navigating distinct major and minor key centers.
Difficulty Rating: 3 (Intermediate). Requires recognition and adaptation to two distinct key centers (F major and A minor) and their respective II-V progressions.
