Dance is a performing art form consisting of purposefully selected sequences of human movement. Dance can be categorized and described by its choreography, by its repertoire of movements, or by its historical period or place of origin. This movement has aesthetic and symbolic value, and is acknowledged as dance by performers and observers within a particular culture.
An important distinction is to be drawn between the contexts of theatrical and participatory dance, although these two categories are not always completely separate; both may have special functions, whether social, ceremonial, competitive, erotic, martial, or sacred/liturgical.
Indian classical music provides accompaniment and dancers of nearly all the styles wear bells around their ankles to counterpoint and complement the percussion. Most classical forms are centred upon dance alone, but performance dance may also appear in opera and other forms of musical theatre.
