Rock

Originating in the 1950s from American rhythm and blues, country, and gospel, rock music is defined by its reliance on the amplified electric guitar, a propulsive rhythm section, and vocal-centric delivery. It evolved from dance-oriented singles to album-length statements, exploring themes from teenage rebellion to complex social critiques. Its primary format shifted to the album, and its medium to the live concert, establishing a potent connection between artist and audience. Through this emphasis on authenticity and performance, rock became a primary engine of youth culture and a dominant commercial and cultural force globally.
