Harmonic Analysis

This progression moves through D♭ (Tonic) → D♭ (Tonic) → G♭ (Subdominant) → D♭ (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.
