Latin jazz is a jazz strand that combines African and Latin melodies. The two main Latin Jazz categories are the Brazilian and the Afro-Cuban. The Brazilian Latin Jazz includes bossa nova and the samba. The Latin Jazz originated in the late 1940s when Dizzy Gillespie and Stan Kenton began to combine the rhythm and structure of the Afro-Cuban jazz, which included salsa, merengue, songo, son, mambo, bolero, charanga and cha cha cha. Afro-Cuban music, exemplified by Machito and his Afro-Cubans, with jazz instruments. Compared to American Jazz, Latin Jazz uses a fixed rhythm, similar to the swung rhythm. Latin Jazz rarely uses a compass played in four, but uses a key form. The conga, the timbal, güiro, and keys are instruments of percussion that contribute to the Latin sound. The Samba originates in the Afro-Brazilian music of century XIX like the Lundu. Use a modified form of the key. Bossa Nova is a hybrid music that uses some of the rhythm of the Samba but influenced by European and American music from Debussy to US jazz. The Bossa Nova originates in the 60's, mainly due to the efforts of Brazilians Antonio Carlos Jobim, João Gilberto, and the American Stan Getz. His most famous song is Garota de Ipanema (The Girl from Ipanema), sung by Gilberto and his wife, Astrud Gilberto.
