The Celtic harp is a triangular frame harp traditional to the Celtic nations of northwest Europe. It is known as cláirseach in Irish, clàrsach in Scottish Gaelic, telenn in Breton and telyn in Welsh. In Ireland and Scotland, it was a wire-strung instrument requiring great skill and long practice to play, and was associated with the Gaelic ruling class. It appears on Irish and Britishcoins, the coat of arms of the Republic of Ireland, Montserrat, the United Kingdom and Canada as well as the flag of Montserrat.
