Afro-Cuban jazz is the earliest form of Latin jazz. It mixes Afro-Cuban clave-based rhythms with jazz harmonies and techniques of improvisation. Afro-Cuban music has deep roots in African ritual and rhythm. The genre emerged in the early 1940s with the Cuban musicians Mario Bauzá and Frank Grillo "Machito" in the band Machito and his Afro-Cubans in New York City. In 1947, the collaborations of bebop trumpeter Dizzy Gillespie and percussionist Chano Pozo brought Afro-Cuban rhythms and instruments, such as the tumbadora and the bongo, into the East Coast jazz scene. Early combinations of jazz with Cuban music, such as "Manteca" and "Mangó Mangüé", were commonly referred to as "Cubop" for Cuban bebop.
During its first decades, the Afro-Cuban jazz movement was stronger in the United States than in Cuba. In the early 1970s, Kenny Dorham and his Orquesta Cubana de Música Moderna, and later Irakere, brought Afro-Cuban jazz into the Cuban music scene, influencing styles such as songo.
