Lore & Background
Rock music originated as rock and roll in the United States during the late 1940s and early 1950s, melding black musical genres such as rhythm and blues and gospel with country and western. Debate surrounds which recording is the first rock and roll record, with contenders including Sister Rosetta Tharpe's "Strange Things Happening Every Day" (1944), Arthur Crudup's "That's All Right" (1946), and Wynonie Harris' "Good Rocking Tonight" (1948). The genre spread to much of the rest of the world and developed into a range of styles by the mid-1960s.
Rock is typically centered on the amplified electric guitar, supported by electric bass guitar and drums, often complemented by keyboards. The basic instrumentation derived from the electric blues band. Rock music traditionally uses simple syncopated rhythms in 4/4 meter with a repetitive snare drum back beat on beats two and four. Melodies often originate from older musical modes such as Dorian and Mixolydian, as well as major and minor scales. Rock lyrics have dealt with themes including romantic love, sex, rebellion, social concerns, and lifestyles.
Rock musicians in the mid-1960s began to advance the album ahead of the single as the dominant form of recorded music expression, with the Beatles at the forefront. By the late 1960s, distinct subgenres emerged including blues rock, folk rock, psychedelic rock, progressive rock, heavy metal, and glam rock. In the second half of the 1970s, punk rock reacted with stripped-down social and political critiques. From the 1990s, alternative rock dominated in forms such as grunge, Britpop, and indie rock. Since the 2010s, rock has lost its position as the pre-eminent popular music genre but remains commercially successful.
Reader's Guide
Rock music's significance lies in its role as both a dominant commercial force and a vehicle for cultural and social movements. From the 1960s to the 2010s, it was the most popular genre in the U.S. and much of the western world, shaping youth culture and subcultures including the hippie movement, punk, goth, and emo. Rock has been associated with political activism, changes in social attitudes to race, sex, and drug use, and is often seen as an expression of youth revolt against adult conformity. The genre's emphasis on musicianship, live performance, and serious themes distinguished it from pop music, with an ideology of authenticity. Rock's legacy includes its influence on later genres such as hip-hop and electronic dance music, and its continued commercial success despite losing pre-eminence after the 2010s. The genre's eclecticism and stylistic diversity make it difficult to bind to a rigid musical definition, as it has borrowed from many other musical and cultural forms.
