Harmonic Highlights:
- The Eb07 functions as a chromatic passing diminished chord, leading smoothly to Dm7.
- Features recurring borrowed ii-V-I progressions (Dm7-G7-C6), creating temporary tonicizations of C major.
- Utilizes strong secondary dominants (A7 for D minor, D7 for G) to direct the harmony and create movement.
- Includes altered dominants like F7#11, adding modern jazz color and tension.
Improvisation Focus: Adapting to transient modulations and secondary dominants.
Difficulty Rating: 4 (Proficient). The frequent shifts between temporary key centers and the use of chromatic passing chords demand a solid grasp of jazz harmony and chord-scale theory.
