Harmonic Analysis

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

The ♭VII–IV–I progression chains two plagal (IV–I) motions together, descending by fourths from the borrowed ♭VII through IV to the tonic. This creates a powerful, grounded resolution that avoids dominant-function harmony entirely. It is a hallmark of classic rock and Britpop.
