Harmonic Highlights:
- The initial four-bar Cm7 vamp strongly establishes a modal minor sound, defining the tune’s core tonality.
- The i-iv progression (Cm7 to Fm7) is foundational to its minor blues structure, characteristic of the genre rather than traditional minor key harmony.
- The Ab7 leading to G7b13 (bVI7 to V7b13) provides characteristic chromatic tension and resolution common in minor blues cadences.
Improvisation Focus: C Minor Blues Scale.
Difficulty Rating: 2 (Intermediate Beginner) - The underlying minor blues form is straightforward, offering clear harmonic targets for improvisers.
