Salsa refers to a fusion of informal dance styles having roots in the Caribbean (especially in the US, Cuba and Puerto Rico), Latin and North America. Salsa is danced to Salsa music. There is a strong African influence in the music and the dance.

Salsa is usually a partner dance, although there are recognized solo steps and some forms are danced in groups of couples, with frequent exchanges of partner. Improvisation and social dancing are important elements of Salsa but it appears as a performance dance too.
