Social dances are dances that have social functions and context. Social dances are intended for participation rather than performance. They are often danced merely to socialise and for entertainment, though they may have ceremonial, competitive and erotic functions.
Many social dances of European origin are in recent centuries partner dances (see Ballroom dance) but elsewhere there may instead be circle dances or line dances.
Dance is an art form, consisting of sequences of body movements with aesthetic and often symbolic value, either improvised or purposefully selected. Dance can be categorized and described by its choreography, by its repertoire of movements or by its historical period or place of origin. Dance is typically performed with musical accompaniment, and sometimes with the dancer simultaneously using a musical instrument themselves.
Two common types of group dance are theatrical and participatory dance. Both types of dance may have special functions, whether social, ceremonial, competitive, erotic, martial, sacred or liturgical. Dance is not solely restricted to performance, as dance is used as a form of exercise and occasionally training for other sports and activities. Dance performances and dancing competitions are found across the world exhibiting various different styles and standards.
Concert dance (also known as performance dance or theatre dance in the United Kingdom) is dance performed for an audience. It is frequently performed in a theatre setting, though this is not a requirement, and it is usually choreographed and performed to set music.
By contrast, social dance and participation dance may be performed without an audience and, typically, these dance forms are neither choreographed nor danced to set music, though there are exceptions. For example, some ceremonial dances and baroque dances blend concert dance with participation dance by having participants assume the role of performer or audience at different moments.
