The cowhorn is one of the oldest instruments in the history of music. Maybe because the raw material was so easily accessible. The cowhorn has a very strong sound which can be heard from far far away. You could say it was the cell phone of the past.

Horn (=nails) is a natural material which stays intact for a very long time. Some horns have been found which have been dated to the 10th century, using pollen analysis. They still look exactly like today's horns.
