Harmonic Highlights
- The primary vamp cycles between Eb minor (i) and Bbm7 (v7), establishing a persistent modal quality without strong functional dominant resolution.
- A Bmaj7 (bVImaj7) chord introduces a chromatic mediant relationship, providing a distinct color shift from the Eb minor tonic.
- The Abm6 (ivm6) functions as a subdominant minor, enriching the minor key palette before resolving to the v7.
Improvisation Focus Eb natural minor scale (Aeolian).
Difficulty Rating 3 (Intermediate). While the core harmony is relatively static, the consistent 5/4 meter presents a significant rhythmic challenge for improvisers.
