Rock music emerged in the 1950s from a fusion of rhythm and blues, country, and other American styles. It is characterized by a strong backbeat, electric guitars, bass, and drums, and a spirit of youthful energy and rebellion that has taken many forms over the decades.

Early rock and roll gave way to the diverse styles of the 1960s and beyond: hard rock, progressive rock, punk, alternative, and countless subgenres. The electric guitar, often played with distortion, became the genre’s signature instrument. Song structures are usually verse-chorus based, though many bands have experimented with longer forms.

Rock has been both a commercial force and a vehicle for social commentary. Live performance, often at high volume, remains central to its identity. Despite repeated predictions of its decline, rock continues to evolve and to attract new generations of players and listeners.
