Latin jazz
Latin jazz is a genre of jazz with Latin American rhythms. Although musicians continually expand its parameters, the term Latin jazz is generally understood to have a more specific meaning than simply jazz from Latin America. Some Latin jazz typically employs rhythms that either have a direct analog in Africa, or exhibit an African influence.
The two main categories of Latin jazz are:
Afro-Cuban jazz—jazz rhythmically based on Cuban popular dance music, often with a rhythm section employing ostinato patterns and/or a clave.
Afro-Brazilian jazz—includes bossa nova and jazz samba.

"Spanish tinge"—The Cuban influence in early jazz and proto-Latin jazz
African American music began incorporating Afro-Cuban musical motifs in the 19th century, when the habanera (Cuban contradanza) gained international popularity. The habanera was the first written music to be rhythmically based on an African motif. The habanera rhythm (also known as congo,tango-congo, or tango ) can be thought of as a combination of tresillo and the backbeat. Wynton Marsalis considers tresillo to be the New Orleans "clave," although technically, the pattern is only half a clave.
