The Duffy School of Irish Dance

Irish dances come in several forms, which can broadly be divided into social dances and performance dances. Irish social dancing can be divided further into céilí and set dancing. Irish set and céili dances are usually danced by couples arranged into formations (sets); frequently squares of four couples, but many other formations are found, also. Irish social dance is a living tradition, and variations in the way a particular dance is danced 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, notable for its rapid leg movements while body and arms are kept largely stationary (it has been popularized since 1994 by the world-famous show "Riverdance"). Aside from public dance performances, there are also stepdance competitions. Most competitive stepdances are solo dances, though many stepdancers also perform and compete using traditional set and céilí dances. When performed as a solo dance, it is generally characterized by a controlled (but not rigid) upper body, straight arms and the quick and precise movements of the feet.

The dancing traditions of Ireland probably grew in tandem with traditions of Irish traditional music. The very first roots were in Pre-Christian Ireland, but Irish dance was also partially influenced by dance forms on the Continent, especially the quadrille dances. Travelling dancing masters taught all over Ireland as late as the early 1900s.

Two types of shoes are worn in step dancing: hardshoes and softshoe. The hardshoe ("heavy shoe", "jig shoe") is unlike the tap shoe, in that the tips and heels are made of fiberglass, instead of metal. The soft shoes, which are called ghillies, resembles a ballet shoe minus the hard toe and the ribbons for laces. Ghillies are only worn by girls while boys wear a black leather shoe which resembles a black jazz shoe with a hard heel. Boys soft-shoe dancing features audible heel clicks.

Irish Dancing schools, like the Duffy School of Irish Dance, have team dresses. However, dancers only need to purchase dresses once they reach higher competition and performance levels.
