Turlough O'Carolan was a blind Celtic harper, composer and singer in Ireland whose great fame is due to his gift for melodic composition.

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 coins, Guinness products, and the coat of arms of the Republic of Ireland, Montserrat, Canada and the United Kingdom.
