- Harmonic Highlights:
- Extensive use of diatonic ii-V-I progressions, frequently resolving to the tonic (Cmaj7, Am7, Dm7, G7).
- Prominent secondary dominant function, notably A7 (V7/ii) leading to Dm7 and D7 (V7/V) leading to G7.
- A strong iiø7-V7b9 progression (Bm7b5-E7b9) explicitly targets the relative minor (Am7), adding harmonic tension and resolution.
- Improvisation Focus: Navigating ii-V-I changes and secondary dominant resolutions through arpeggios and appropriate modes.
- Difficulty Rating: 3 (Intermediate). It requires familiarity with functional harmony and common jazz chord substitutions beyond basic diatonic movement.
