Harmonic Highlights
- The prominent bVII7 (Db7) resolving to the vi minor (Cm7) creates a distinctive “backdoor” sound, frequently repeated for a vamp feel.
- Inclusion of a I7 (Eb7) on the tonic indicates a strong blues influence within the Eb major key center.
- A sophisticated dominant chain (D7b13 -> G7b9) functions as a V/V/vi -> V/vi progression, leading to the relative minor (Cm7) with altered dominant voicings.
Improvisation Focus C Minor Blues Scale
Difficulty Rating 4 (Advanced). The blend of sophisticated dominant alterations and an unconventional repeated vamp requires an advanced understanding of functional harmony and modal interchange.
