Harmonic Analysis

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

The I–♭VII progression borrows the flat-seven chord from Mixolydian mode, giving a major-key vamp a bluesy, rootsy character. Its simplicity makes it a favorite in classic rock and folk-rock. The ♭VII adds a gritty tension that avoids the pull of a dominant V chord.

Song Examples

Sweet Child O' Mine (chorus), Guns N' Roses
