Harmonic Highlights:
- Prominent use of secondary ii-V-I progressions, exemplified by Em7b5-A7b9 resolving to Dm7 (iiø7-V7 to vi).
- Frequent tonicization of related key centers through ii-V movements, like Dm7-G7 targeting the V (C major) and Cm7-F7 targeting the IV (Bb major).
- The A7b9 functions as a V7b9 secondary dominant, adding a characteristic jazz tension before resolving to Dm7.
Improvisation Focus: Chord tone outlining and navigating frequent secondary ii-V changes.
Difficulty Rating: 3 (Intermediate). Requires solid recognition and execution of multiple secondary ii-V progressions beyond the diatonic key.
