Harmonic Highlights:
- Extensive use of the ii-V-I progression (Gm7-C7-Fmaj7) establishes the F major key center repeatedly.
- Inclusion of a secondary dominant G7 (V7/V) that resolves to the ii chord (Gm7), creating a V7/V - ii - V motion.
- Utilization of the vi-ii-V-I progression (Dm7-G7-C7-Fmaj7), a common jazz turnaround.
Improvisation Focus: F Major scale and its diatonic modes (Dorian for Gm7, Mixolydian for C7).
Difficulty Rating: 2 (Intermediate) - The harmony is primarily diatonic with standard jazz extensions, requiring solid command of functional harmony and modal changes within the key.
