Harmonic Highlights:
- Frequent ii-V-I progressions are employed to tonicize the subdominant (F major) and the relative minor (A minor).
- Utilizes secondary dominants like Am7-D7 (V/V) to build tension and lead towards the dominant.
- Features a sophisticated minor ii-V (Am7b5-D7) directly targeting the dominant (Gm7).
- Incorporates Bbmaj7 (bVIImaj7), indicating modal interchange or a backdoor dominant function.
Improvisation Focus: Navigating diverse ii-V-I progressions and tonicizations.
Difficulty Rating: 3 (Intermediate). The frequent tonicizations and secondary dominant movements require a solid understanding of chord-scale theory beyond simple diatonic improvisation.
