Salsa is a lively Latin dance of quick hip movement. Dance salsa, a salsa class, salsa music.
It came together in New York in the 1960s and 70s among Cuban and Puerto Rican musicians rather than in any one country. The basic step is quick-quick-slow over eight beats. The word is the Spanish for sauce, and it names the dip too.
