This instrument, as its name implies, consists of a bar of steel bent in triangular form with one angle open. It is hung by a cord to a music stand or any suitable bracket and is struck with a small steel rod. It produces a bright, tinkling sound, without definite pitch, and is used to enhance light, fairy-like movements by marking the rhythm. The trill is of frequent occurrence and is executed by alternately striking two sides of the triangle.
