Harmonic Highlights
- Establishes key with a foundational III-VI-II-V-I progression (Am7-Dm7-Gm7-C7-Fmaj7), expanding beyond typical ii-V-I movements.
- Frequent use of diatonic descending perfect fourths (e.g., Am7-Dm7), creating smooth voice leading.
- Features recurring ii-V movements (Cm7-F7) that tonicize the IV chord (Bbmaj7), adding secondary dominant function.
- The C7sus chord provides temporary dominant suspension, adding harmonic color and delaying resolution.
Improvisation Focus Focus on the F major scale and its diatonic modes, adapting to the temporary tonicization of Bb major via Cm7-F7.
Difficulty Rating 3 (Intermediate) - The chord changes feature common jazz progressions but introduce clear temporary tonicizations requiring harmonic flexibility.
