Salsa is the Spanish word for "sauce" denoting a "spicy" and "hot" flavor to this popular dance style to a complex mix of many different rhythms. There are indications the term Salsa was coined by radio disc jockeys in Puerto Rico as early as the 1960's. Later associated with a New York sound developed by Puerto Rican musicians, Salsa is considered the national music and dance of Puerto Rico. The fusion of an Afro-Cuban beat with enhanced jazz textures results in an aggressive high energy pulse which has become popular everywhere. Many of the patterns are closely related to those of the Mambo and Cha-Cha.
