Horn may refer to a number of quite different musical instruments.The earliest horns were still made of real animal-horn or seashells, while later they could also be made from metal or wood.However all types still retained at last to some degree the original horn or shell form.Other later instruments such as trumpets very much were still built on the same idea.
Other cultures which used horn-instruments included the Easterlings, Eriadorians, gondorians, Haradrim, northmen, Númenóreans and hobbits.Bovine horn instruments were associated with Oromë's folk and mountain fays while seashell hor s or conches were traditionally associated with the Merfolk.
