Salsa dance movements originate from the Cuban Son dancing of the 1930s more specifically through the beat of Son Montuno with strong influences from the dance of Danzon, Mambo, Guaguanco and other Afro-Cuban folkloric dancing. Salsa is typically a partner dance, although there are recognized solo forms (Floor Shines/ Shines), line dancing (suelta), and Rueda de Casino, where groups of couples exchange partners in a circle. Women traditionally wear short/skirted latin outfits and men wear tight fitting shirts and pants.
