Ireland

Ireland is the third-largest island in Europe and the twentieth-largest island in the world. It lies to the northwest of continental Europe and is surrounded by hundreds of islands and islets. To the east of Ireland is Great Britain, separated from it by the Irish Sea. 

Irish dance is a group of traditional dance forms originating in Ireland which can broadly be divided into social dance and performance dances. Irish social dances can be divided further into céilí and set dancing. Irish set dances are quadrilles, danced by 4 couples arranged in a square, while céilí dances are danced by varied formations (ceili) of couples of 2 to 16 people. In addition to their formation, there are significant stylistic differences between these two forms of social dance. Irish social dance is a living tradition, and variations in particular dances are found across the Irish dance community; in some places, dances are deliberately modified and new dances are choreographed.

Irish performance dancing is traditionally referred to as stepdance. Irish stepdance, popularized in 1994 by the world-famous show "Riverdance", is notable for its rapid leg movements, body and arms being kept largely stationary. Most competitive stepdances are solo dances, though many stepdancers also perform and compete using céilí dances. The solo stepdance is generally characterized by a controlled but not rigid upper body, straight arms, and quick, precise movements of the feet. The solo dances can either be in "soft shoe" or hard shoe".
