Contemporary with Sydney Owenson, this example of an Irish harp was made by John Egan in Dublin in 1820. It is a frame harp (the other two types are the bow, or arched, harp and the angle harp). The structure, basically the same in all harps, consists of strings of unequal length which run from the neck of the instrument to the sound box. The Irish harp features a curved pillar and seven ditals (levers), which are depressed by the fingers in order to change the pitch of the notes.
