Harmonic Highlights:
- Establishes a clear F major tonality through common diatonic progressions like Imaj7-iim7-iiim7-IVmaj7.
- Features recurring ii-V-I movements (Gm7-C7-F6) anchoring the progression within the tonic key.
- Introduces a significant harmonic departure with the Ebm7-Ab7 (ii-V of Db major), creating a strong temporary tonicization or modulation distant from the tonic.
Improvisation Focus: Understanding and navigating ii-V progressions across different key centers.
Difficulty Rating: 3 (Intermediate) because while it features straightforward diatonic harmony, the Ebm7-Ab7 sequence requires navigating a sudden, distant key change.
