Harmonic Highlights:
- Prominent use of C7b13 (V7/iv) as a secondary dominant, leading directly to Fm7.
- Frequent i-V7b9 progressions (Cm7-G7b9) firmly establish the C minor tonality.
- A sudden, distant modulation via Ebm7-Ab7 (ii-V of Db major), characteristic of bebop chromaticism.
Improvisation Focus: Melodic Minor scale and its modes.
Difficulty Rating: 4 (Advanced). The harmonic complexity involving altered dominants and distant modulations demands advanced theoretical and improvisational proficiency.
