Celtic Harp (Clàrsach or Cláirseach; depends on the pronunciation of Irish or Scottish Gaelic) is a medieval musical instrument similar to a harp, whose body consists of one piece of wood with usually 30 bronze strings with a smaller spacing.
The present form of the Celtic harp is based on the reconstruction of the original Scottish harp Queen Mara or Irish Trinity, which can be seen at Trinity College.
