Rock music is a genre of popular music that originated as `` rock and roll '' in the United States in the early 1950s , and developed into a range of different styles in the 1960s and later , particularly in the United Kingdom and the United States . It has its roots in 1940s and 1950s rock and roll , a style which drew heavily on the African-American genres of blues and rhythm and blues , and from country music . Rock music also drew strongly on a number of other genres such as electric blues and folk , and incorporated influences from jazz , classical and other musical styles . Musically , rock has centered on the electric guitar , usually as part of a rock group with electric bass and drums and one or more singers . Typically , rock is song-based music usually with a 4/4 time signature using a verse-chorus form , but the genre has become extremely diverse . Like pop music , lyrics often stress romantic love but also address a wide variety of other themes that are frequently social or political .   By the late 1960s `` classic rock '' period , a number of distinct rock music subgenres had emerged , including hybrids like blues rock , folk rock , country rock , raga rock , and jazz-rock , many of which contributed to the development of psychedelic rock , which was influenced by the countercultural psychedelic and hippie scene . New genres that emerged included progressive rock , which extended the artistic elements ; glam rock , which highlighted showmanship and visual style ; and the diverse and enduring subgenre of heavy metal , which emphasized volume , power , and speed . In the second half of the 1970s , punk rock reacted by producing stripped-down , energetic social and political critiques . Punk was an influence in the 1980s on new wave , post-punk and eventually alternative rock . From the 1990s alternative rock began to dominate rock music and break into the mainstream in the form of grunge , Britpop , and indie rock . Further fusion subgenres have since emerged , including pop punk , rap rock , and rap metal , as well as conscious attempts to revisit rock 's history , including the garage rock/post-punk and synth-pop revivals at the beginning of the 2000s -LRB- decade -RRB- .   Rock music has also embodied and served as the vehicle for cultural and social movements , leading to major subcultures including mods and rockers in the UK and the hippie counterculture that spread out from San Francisco in the US in the 1960s . Similarly , 1970s punk culture spawned the goth and emo subcultures . Inheriting the folk tradition of the protest song , rock music has been associated with political activism as well as changes in social attitudes to race , sex and drug use , and is often seen as an expression of youth revolt against adult consumerism and conformity .
