- Oscillation between the minor
v9chord (Cm9) and a dominantbVI9chord (Db9). - The
Db9functions as a Neapolitan dominant, creating a distinctive, unresolved tension within the F minor key center. - A modal vamp structure prioritizes rhythmic groove and harmonic color over traditional functional progression.
- The continuous cycle challenges conventional tension-release expectations, demanding an ear for sustained mood.
Improvisation Focus: C minor blues scale for its ability to unify the minor v and add tension over the dominant bVI.
Difficulty Rating: 3 (Intermediate) – The two-chord vamp is harmonically simple yet demands creative melodic and rhythmic invention to navigate the unique tension of the bVI9 and maintain interest.
