B7b9b13 -> Em7Resolution (Minor)2

Harmonic Highlights:

  • The progression establishes a strong E minor modal center (Em7) for two measures, creating a stable, contemplative mood.
  • The C6 chord (bVI) provides a momentary major quality before the dominant, adding a distinct color within the minor key.
  • The B7b9b13 is a highly altered dominant, generating strong tension and a clear resolution to Em7, reinforcing the E minor tonality.
  • The two-measure duration for each chord type creates a slow-moving, deliberate harmonic rhythm characteristic of the tune’s groove.

Improvisation Focus: E Harmonic Minor scale.

Difficulty Rating: 4 (Advanced). The altered dominant chord (B7b9b13) and the specific quality of the C6 require precise scale knowledge and careful voice leading for effective improvisation.
