Harmonic Highlights
- The progression firmly establishes a C minor tonality (Cm6, Fm7, Dm7b5-G7b9-Cm6) despite the stated C major key center, indicating prevalent modal interchange.
- Extensive use of altered dominant chords (G7b9, D7#9, G13b9) creates rich tension and implies harmonic or melodic minor scalar choices for resolution.
- A brief ii-V to the dominant minor (Am7b5-D7#9 implying G minor) adds a momentary departure from the tonic minor, enhancing harmonic movement.
Improvisation Focus C Harmonic Minor scale, especially for navigating the V7b9 chords.
Difficulty Rating 4 (Advanced) - The consistent minor tonality with frequent altered dominants and modal interchange requires a sophisticated harmonic understanding.
