HORN is also a sort of musical instrument of the wind kind; chiefly used in hunting, to animate and bring together the dogs and the hunters. The term anciently was, wind a horn; all horns being in those times compassed: but since straight horns are come in fashion, they say blow a horn, and sometimes found a horn.—There are various lessons on a horn; as the recheat, double recheat, royal recheat, running or farewell recheat, &c. See RECHEAT.
