Harmonic Highlights:
- Frequent tonicization of the subdominant (Cmaj7 as IV), often approached by G7 (V/IV), establishing strong temporary resolutions to the IV chord.
- Extended chain of secondary dominants and related ii-V progressions (e.g., F#m7b5-B7-E7-Am7-D7), showcasing intricate movement through temporary key areas.
- Prominent use of ii-V-I/IV cadences (Dm7-G7-Cmaj7), utilizing standard jazz vocabulary to resolve to the subdominant.
Improvisation Focus: Navigating ii-V-I progressions and secondary dominants effectively.
Difficulty Rating: 4 (Advanced Intermediate). The frequent tonicization of the subdominant and extended secondary dominant chains demand sophisticated chord-scale awareness and quick harmonic anticipation.
