Salsa is a syncretic dance form with origins from Cuba as the meeting point of Spanish (European) and African cultures. Salsa is normally a partner dance, although there are recognized solo forms such as solo dancing "suelta" and "Rueda de Casino" where multiple couples exchange partners in a circle. Salsa can be improvised or performed with a set routine. Salsa is popular throughout Latin America as well as in North America, Europe, Australia, and some countries in Asia and the Middle East. It is fast becoming a global phenomenon.
