The I–bVII–IV progression borrows the bVII from the parallel minor — Mixolydian territory — to give rock its swaggering, stadium-sized sound. The bVII (D) slips outside the major scale for a bluesy, grounded color that the IV then amplifies before returning home. That single borrowed chord separates this from standard major-key rock and supplies the anthemic, slightly dangerous edge of hard rock and Southern rock.
