The horn is a brass instrument that consists of tubing wrapped into a coiled form, now with finger-operated valves to help control the pitch but originally without valves to control the pitch (this kind of horn is now called a natural horn, which is a retronym since at that time, all French horns had were natural horns.) The instrument was first developed in England as a hunting horn in about 1650. The French refer to the modern valved instrument as the horn of harmony, the Germans call it the hunting horn, and the English and Americans call it the French horn.
