Rock Music

The harmony of 'Rock Music' is built on foundational power-pop and punk-rock structures, specifically the i-VI-III-VII progression. This sequence is distinctive for its lack of a major V chord (G# major), instead opting for the natural minor's VII (B major). This choice removes the 'classical' tension of the leading tone, resulting in a driving, modal sound that aligns with the song's aggressive electronic production and industrial-rock aesthetic.
