Salsa is a Latin dance form with origins from the Cuban Son and Afro-Cuban dance (specifically Afro-Cuban rumba). The Afro-Cuban ritual dances form a huge group of Cuban dances and reflect the four main groups of Africans that were transported to Cuba. It is generally associated with the salsa music style, although it may be danced under other types of Latin music.Salsa is normally a partner dance, although there are forms such as a line dance form "Salsa suelta", where the dancers dance individually and a round dance form "Rueda de Casino" where multiple couples exchange partners in a circle. Salsa can be improvised or performed with a set routine.Salsa is a popular social dance throughout Latin America as well as in North America, Europe, Australia, and some countries in Asia and the Middle East.
