Harmonic Highlights
- The progression is a static i7 – IV7 vamp, alternating between Bbm7 and Eb7 to create a consistent rhythmic groove.
- It utilizes a Bb Dorian modal framework, as the Eb7 chord introduces the characteristic natural 6th (G natural) against the minor tonality.
- The harmony avoids traditional functional cadences like the ii-V-I, relying instead on cyclical movement that lacks a dominant V7 resolution.
- The syncopated synthesizer bassline acts as the primary harmonic anchor, defining the tonal center through repetitive root-position movement.

Difficulty Rating
2/5. The two-chord structure is harmonically simple for beginners, but the primary challenge lies in maintaining rhythmic precision and melodic inventiveness over an extended period.
