Sean-nós dance

Sean-nós dance (/ˈʃænoʊs/ SHAN-ohss; Irish: damhsa ar an sean nós [ˈd̪ˠəusˠə ɛɾʲ ə ˈʃan̪ˠ n̪ˠoːsˠ], lit. 'old style dancing') is an older style of traditional solo Irish dance. It is a casual dance form, as opposed to the more formal and competition-oriented form of Irish stepdance.

Sean nós in Irish means "old style", and is applied to the dance form as well as sean-nós singing. These now less-common forms of Irish dance and traditional Irish singing have been documented in Irish history and by ethnomusicologists, but are still alive in parts of the Irish music scene.
