Harmonic Highlights:
- The core Am7 - Bm7/E vamp establishes a distinctive modal A minor center, where Bm7/E functions as a sustained dominant (Esus4 with added notes) or a ii/V, avoiding traditional V7-i resolution.
- The Bm7/E chord (B-D-F#-A over E) notably features an F#, strongly indicating the A Dorian mode as the prevailing harmonic flavor.
- The extended absence of a standard E7 (V7) chord contributes to an open, floating harmonic rhythm, prioritizing modality over strong functional pulls.
- The Dm7 - Am7 progression provides a classic iv-i minor resolution, reaffirming the tonic within the established modal framework.
Improvisation Focus: A Dorian scale.
Difficulty Rating: 2 (Beginner-Intermediate). The consistent modal vamp and repetitive chord changes make the primary scale choice straightforward despite the slightly nuanced Bm7/E chord voicing.
