G7b13 -> Cm7Resolution (Minor)1

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.
