Kwela is a pennywhistle-based street music from southern Africa with jazzy underpinnings and a distinctive, skiffle-like beat. It evolved from the marabi sound and brought South African music to international prominence in the 1950s. The music has its roots in southern Africa but later adaptations of this and many other African folk idioms have permeated Western music (listen to the albums A Swingin' Safari by the Bert Kaempfert Orchestra (1962) and Graceland by Paul Simon (1986)), giving modern South African music, particularly jazz, much of its distinctive sound and lilting swagger.
