- 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.
