Harmonic Highlights:
- Prominent use of the bIII major (Ebmaj7) and v minor (Gm7) as temporary tonic centers, departing from the C minor tonic.
- Frequent deployment of iiø7-V7b9 progressions (Am7b5-D7b9) and secondary dominants (C7b9 to Fm7) to create tension and resolution.
- Includes a tritone substitution (Ab7#11 for D7) leading to Gm7, adding an advanced harmonic color and tension.
Improvisation Focus: The Altered Scale, particularly over the D7b9, C7b9, and the Lydian Dominant quality implied by Ab7#11.
Difficulty Rating: 4 (Advanced Intermediate). The piece requires navigating numerous temporary tonicizations, altered dominants, and a tritone substitution within a dynamic minor key framework.
