English music has its origins in folk music, with songs from the Middle Ages still being popular today. In medieval times, choral music was most popular. Some influential early English composers included John Dunstable and Henry Purcell. In the 20th century, Benjamin Britten and Ralph Vaughan Williams composed choral works and solo songs. Musical theater flourished with composers like Noel Coward, Lionel Bart, and Andrew Lloyd Webber writing famous musicals. Rock music also emerged as a dominant genre in England with bands like The Beatles, The Rolling Stones, and solo artists such as Elton John, Freddie Mercury, and Sting achieving great success.
