Harmonic Analysis

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

The I–♭VII–IV–I turnaround chains two plagal cadences together, descending by fourths from the borrowed ♭VII through IV back to the tonic. This plagal double descent avoids dominant harmony entirely, giving it a modal, earthy quality. It is a signature pattern in Britpop and classic rock.
