A musical instrument of the wind kind: the earliest, from which the instrument derived its name, were the horns of animals, and these are still used extensively in remote or uncivilized districts. Considered as a modern musical instrument, they are chiefly made of metals, and of various kinds or forms. The French horn is a long tube, narrow at the top, and increasing in diameter to the end, where its mouth is very wide. It is curled up in several rings, for the convenience of carriage and performance. The trumpet and the bugle horn are noticed under their respective heads.
