This venerable instrument, the least impaired Gaelic Harp existing, is known as Queen Mary's Harp.

It is small, being only 31 inches high and 18 inches from back to front. It was played resting upon the left knee and against the left shoulder of the performer, whose left hand touched the upper strings. The comb is from 2½ to 3¼ inches high. It is inserted obliquely in the sound chest, and projects about 14 inches.
