A triangular frame harp developed in Ireland and the Scottish Highlands. Referred to as the Gaelic harp, Irish harp, cruit, cláirseach or clàrsach, and wire-strung harp. It differs in several respects from both early harps in the rest of Europe, and modern harps, as it is played on the left shoulder and its strings are traditionally made of metal.
