Harmonic Highlights:
- Frequent deployment of ii-V-I progressions, notably targeting the tonic (Am7-D7-G) and the IV chord (Dm7-G7-C).
- Strong temporary tonicization of the relative minor via F#m7b5-B7-Em7.
- Recurring use of the bluesy IV7 (C7) in place of Cmaj7, creating a dominant pull to the subdominant.
- Inclusion of the secondary dominant A7 (V7/ii) adds further harmonic color and direction.
Improvisation Focus: Navigating ii-V-I changes with appropriate chord-scales and arpeggios.
Difficulty Rating: 4 (Advanced Intermediate) - Requires facility in applying specific chord-scales over numerous ii-V-I progressions and temporary tonicizations.
