Harmonic Analysis

This progression moves through B♭ (Tonic) → A♭ (Subtonic) → E♭ (Subdominant).

The I–♭VII–IV progression draws from the Mixolydian mode, using the flatted seventh degree to create a bluesy, rock-oriented sound. It avoids the traditional dominant-tonic pull, giving it a laid-back, groovy character. This pattern is a staple of classic and Southern rock.
