The Beatles were an English rock band, formed in Liverpool in 1960. With members John Lennon, Paul McCartney, George Harrison and Ringo Starr, they became widely regarded as the foremost and most influential act of the rock era. Rooted in skiffle, beat, and 1950s rock and roll, the Beatles later experimented with several genres, ranging from pop ballads and Indian music to psychedelia and hard rock, often incorporating classical elements in innovative ways. The group was inducted into the Rock and Roll Hall of Fame in 1988, with all four being inducted individually as well. None of The Beatles could read sheet music, but they could apparently write it - all of them learned to play by ear.
