What is a harp indicative of when it is located on a gravestone? Sometimes, it is a nod to the Irish heritage of the deceased. The harp has become associated with Ireland because of the prominence of harp use among musicians and poets in the Celtic and Gaelic cultures. Harps are also a symbol of praise to God, in the Christian tradition. The angels and saints are often portrayed playing a harp for God, since they are the most holy and able to sing Gods praises. On a gravestone, a harp may suggest that a person was very active in the church.
