Harmonic Analysis

This progression moves through F♯ (Tonic) → F♯ (Tonic) → B (Subdominant) → F♯ (Tonic).

This four-bar phrase lingers on the tonic before briefly visiting the subdominant and returning. It reflects the opening bars of a 12-bar blues and works as a standalone vamp or riff foundation.
