Rock music is a genre of popular music that entered the mainstream in the 1960s. It has its roots in 1940s and 1950s rock and roll, rhythm and blues, country music and also drew on folk music, jazz and classical music. The sound of rock often revolves around the guitar back beat laid down by a rhythm section of electric bass guitar, drums, and keyboard instruments such as organ, piano, or, since the 1970s, synthesizers. A group of musicians specializing in rock music is called a rock band or rock group. Chick is slang for woman.
