Rock and roll originated in the United States in the late 1940s and early 1950s. It was heavily influenced by jazz, blues, and country music, taking several elements from these genres to become a completely revolutionary style. One of the most important changes brought on by rock and roll was the idea of replacing the traditional big jazz band by a small group of performers, however different from the traditional solo artists playing blues, with a vocalist carrying a simple and catchy melody, with the intent of making the audience dance.
