The Bo Diddley beat is a syncopated musical rhythm that is widely used in rock and roll and pop music. The beat is named after rhythm and blues musician Bo Diddley, who introduced and popularized the beat with his self-titled debut single, "Bo Diddley", in 1955. The beat is essentially the Afro-Cuban clave rhythm or based on the clave or a variation thereof.

Rock and roll is a genre of popular music that evolved in the United States during the late 1940s and early 1950s. It originated from African American music such as jazz, rhythm and blues, boogie-woogie, electric blues, gospel, jump blues, as well as country music. While rock and roll's formative elements can be heard in blues records from the 1920s and in country records of the 1930s, the genre did not acquire its name until 1954.
