Harmonic Highlights
- The core progression establishes a static C minor tonality, repeatedly cycling through distinct Cm chord qualities (Cm, Cm/maj7, Cm7, Cm6) over a pedal C.
- The prominent Cm/maj7 (C minor major seven) chord introduces a characteristic minor sound with a major seventh, often implying C melodic minor harmony.
- A classic iiø-V7b9 (
Dm7b5, G7b9) resolves directly to C minor, reinforcing the tonic and providing traditional jazz dominant tension.
Improvisation Focus: C Melodic Minor Scale.
Difficulty Rating: 3 (Intermediate). While the form is a repeating vamp, effectively navigating the nuanced minor chord qualities and the iiø-V7b9 requires a solid understanding of minor harmony and altered dominant scales.
