Rueda de Casino (Rueda, Casino Rueda, Salsa Rueda) is a particular type of round dancing of Salsa. It was developed inHavana, Cuba in the late 1950s and early 1960s by the famous group Guaracheros de Regla and one of its main choreographers and creators was Jorge Alfaro from San Miguel del Padrn, a soloist of a comparsa.
Pairs of dancers form a circle, with dance moves called out by one person, a caller (or Lder or cantante in Spanish). Many moves have hand signs to complement the calls; these are useful in noisy venues, where spoken calls might not be easily heard. Many of the moves involve the swapping of partners. Ref: Wikipedia
