Harmonic Analysis

This progression moves through D♭ (Tonic) → G♭ (Subdominant) → A♭ (Dominant) → Fm (Mediant) → Bbm (Submediant).

A Classical-era progression that begins with a standard cadential setup but diverts through iii to vi, creating a deceptive resolution followed by a mediant color. This technique extends harmonic journeys in sonata and rondo forms.
