Harmonic Analysis

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

The IV–I–V–I progression pairs a plagal cadence (IV–I) with an authentic cadence (V–I), creating a double resolution. Each half provides its own satisfying arrival at the tonic, making this a powerful closing gesture. It is common in hymns, gospel music, and classical finales.
