Harmonic Analysis

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

A plagal cadence enhanced by modal mixture, darkening the major IV to minor iv before resolving to the tonic. The chromatic lowering of the sixth scale degree creates a poignant, ♭ittersweet quality beloved by Romantic-era composers.
