Stepdancing as a modern form is descended directly from old-style step dancing. There are several different forms of stepdancing in Ireland (including sean-nós dancing and old style stepdancing), but the style most familiar to the public at large is the Munster, or southern, form, which has been formalised by An Coimisiún le Rincí Gaelacha—the Irish Dancing Commission.
Irish stepdancing is primarily done in competitions, public performances or other formal settings.
Sean-nós dancing in the Irish diaspora
As Irish people emigrate all over the world, they take their cultural traditions with them. Many people theorise[who?] that Sean-nós dancing has influenced various other forms of traditional solo dance, especially those found in areas with strong Irish communities. Historically, it is likely that sean-nós dance influenced the development of many American and Canadian traditional percussive dance forms, such as buck dancing, flatfooting, clogging, and tap dancing. Sean-nós dancing in the United States and Canada is most commonly seen at folk festivals, although dance workshops are beginning to introduce the style more widely.
Old-Style step dancing
Old-style step dancing is a tradition related to, yet distinct from, sean-nós dancing, though it is sometimes called "Munster-style sean-nós". Old-style step dancing evolved in the late 18th and early 19th century from the dancing of traveling Irish dance masters. The dance masters slowly formalised and transformed both solo and social dances. Modern masters of old-style step dancing style can trace the lineage of their steps directly back to 18th century dancers.
The Irish dance masters refined and codified indigenous Irish dance traditions. Rules emerged about proper upper body, arm, and foot placement. Also, dancers were instructed to dance a step twice—first with the right foot then with the left. Old-style step dancers dance with arms loosely (but not rigidly) at their sides. They dance in a limited space. There is an emphasis on making percussive sound with the toes. The Irish dance masters of this period also choreographed particular steps to particular tunes in traditional music creating the solo set dances such as the Blackbird, St. Patrick's Day, and the Job of Journey Work, which also persist in Modern Irish Step Dancing. In this context, "set dance" signifies a separate tradition from the social dance tradition also called set dance.
