Rock and roll is a genre of music that evolved in the United States in the late 1940s and became popular in the early 1950s. It later spawned the various sub-genres of what is now called simply rock. Rock music is a form of popular music with a prominent vocal melody accompanied by guitar, drums, and bass. Many styles of rock music also use keyboard instruments such as organ, piano, or synthesizers.
