Latin jazz has two main varieties: Afro-Cuban and Brazilian jazz. Afro-Cuban jazz was played in the U.S. directly after the bebop period, while Brazilian jazz became more popular in the 1960s. Afro-Cuban jazz began as a movement in the mid-1950s as bebop musicians such as Dizzy Gillespie and Billy Taylor started Afro-Cuban bands influenced by such Cuban and Puerto Rican musicians as Xavier Cugat, Tito Puente, and Arturo Sandoval. Brazilian jazz such as bossa nova is derived from samba, with influences from jazz and other 20th century classical and popular music styles. Bossa is generally moderately paced, with melodies sung in Portuguese or English.
