Dance

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.

Dance may also be participated in alone as a form of exercise or self expression. Dancing is common human behaviour, and does not necessarily require specific choreography.

Theatrical dance, also called performance or concert dance, is intended primarily as a spectacle, usually a performance upon a stage by virtuoso dancers. It often tells a story, potentially using mime, costume and scenery, or it may interpret the musical accompaniment, which is often specially composed and performed in a theatre setting but it is not a requirement. Examples are Western ballet and modern dance, Classical Indian dance such as Bharatanatyam, and Chinese and Japanese song and dance dramas, such as the dragon dance. Most classical forms are centred upon dance alone, but performance dance may also appear in opera and other forms of musical theatre.

Participatory dance, whether it be a folk dance, a social dance, a group dance such as a line, circle, chain or square dance, or a partner dance, such as in Western ballroom dancing, is undertaken primarily for a common purpose, such as social interaction or exercise, or building flexibility of participants rather than to serve any benefit to onlookers. Such dance seldom has any narrative. A group dance and a corps de ballet, a social partner dance and a pas de deux, differ profoundly. Even a solo dance or interpretive dance may be undertaken solely for the satisfaction of the dancer. Participatory dancers often all employ the same movements and steps but, for example, in the rave culture of electronic dance music, vast crowds may engage in free dance, uncoordinated with those around them. On the other hand, some cultures lay down strict rules as to the particular dances people may or must participate.

Archaeological evidence for early dance includes 10,000-years-old paintings in Madhya Pradesh, India at the Rock Shelters of Bhimbetka, and Egyptian tomb paintings depicting dancing figures, dated c. 3300 BC. It has been proposed that before the invention of written languages, dance was an important part of the oral and performance methods of passing stories down from one generation to the next. The use of dance in ecstatic trance states and healing rituals (as observed today in many contemporary indigenous cultures) is thought to have been another early factor in the social development of dance.

References to dance can be found in very early recorded history; Greek dance (choros) is referred to by Plato, Aristotle, Plutarch and Lucian. The Bible and Talmud refer to many events related to dance, and contain over 30 different dance terms. In Chinese pottery as early as the Neolithic period, groups of people are depicted dancing in a line holding hands, and the earliest Chinese word for "dance" is found written in the oracle bones. Dance is described in the Lüshi Chunqiu. Primitive dance in ancient China was associated with sorcery and shamanic rituals.

During the first millennium BCE in India, many texts were composed which attempted to codify aspects of daily life. Bharata Muni's Natya Shastra (literally "the text of dramaturgy") is one early text. It mainly deals with drama, in which dance plays an important part in Indian culture. A strong continuous tradition of dance has since continued in India, through to modern times, where it continues to play a role in culture, ritual, and the Bollywood entertainment industry. Many other contemporary dance forms can likewise be traced back to historical, traditional, ceremonial, and ethnic dance.
