Be-Bop is an instrumental jazz standard with no lyrics, composed by Dizzy Gillespie, who is credited as its sole writer. The tune is dated to 1945, when the Dizzy Gillespie Sextet recorded it. The recording was issued on the 78-rpm single "Salted Peanuts / Be-Bop", where the tune appears on the B side. It is considered a bebop tune that helped define the style, and it is commonly called a bebop reference standard. Later performances include a 1946 version by the Howard McGhee Quintet and a 1956 recording by Stan Getz and Sonny Stitt, released on the album For Musicians Only in 1958. Its title and its role in the repertoire make it one of the most frequently cited examples of the bebop idiom.
