exhibition swimming in which the movements of one or more swimmers are synchronized with a musical accompaniment. Because of a similarity to dance, it is sometimes called water ballet, especially in theatrical situations. The sport developed in the United States in the 1930s. Synchronized swimming is an organized amateur sport in many areas of the world under the general supervision of the Fédération Internationale de Natation Amateur (FINA; International Amateur Swimming Federation), which publishes a list of stunts (movements or figures) accepted in competition. The FINA recognized synchronized swimming in 1954. Swimmers in solo, duet, or team (four to eight persons) competition perform several required stunts together with several of their own choice. At the Olympics and in world competition, they are scored by two panels of five judges on execution and style, both of the individual stunts and of their musical routine as a whole.

Synchronized swimming for women was admitted as Olympic (Olympic Games) competition in 1984. The competition originally consisted of solo and duet events, but both events were dropped at the 1996 Games in favour of a single eight-member team event. The duet event returned to the Olympic program in 2000. Swimmers were judged on both compulsory and optional figures.
