Harmonic Highlights:
- The prominent use of C9#5 (V/iv) resolving to Fm7 (iv), showcasing an altered dominant quality and secondary dominant function within the C minor key.
- The distinctive Db7 (bII7) chord which deceptively resolves to C9#5 (V/iv) rather than the expected Cm7, creating an extended tension-release cycle.
- A clear iiø7-V7b9-i minor progression (Dm7b5-G7b9-Cm7) firmly establishes the C minor tonic and features the characteristic b9 alteration.
- The chromatic dominant sequence F7-B7-Bb7, particularly the B7, introduces significant chromaticism and a brief departure from conventional dominant resolutions.
Improvisation Focus: Altered scale (Super Locrian) on dominant chords.
Difficulty Rating: 4 - Features numerous altered dominant chords, non-standard resolutions, and a sophisticated harmonic structure demanding advanced conceptual understanding.
