Harmonic Highlights:
- Initiates on the relative major (Ebmaj7, bIII), establishing a characteristic minor key entry.
- Features multiple robust ii-V progressions (e.g., Dm7-G7 to Cm, Fm7-Bb7 to Eb), driving strong harmonic motion.
- Incorporates chromatic dominants like Db7 (bII7, tritone sub for G7) and C7b9, adding sophisticated tension.
- The unexpected Cmaj7 resolution suggests a Picardy third or a significant shift in tonic quality.
Improvisation Focus: C Harmonic Minor scale and its derived modes are paramount for navigating the V7 chords and minor tonality.
Difficulty Rating: 4 (Advanced Intermediate). The combination of frequent ii-V changes, chromatic dominants, and unexpected major tonicization requires advanced harmonic understanding.
