Horn

1. A noisemaker (as at parties or games) that makes a loud noise when you blow through it. Each party goer received a small plastic horn.
2. One of the bony outgrowths on the heads of certain animals such as deer and goats. Deer shed their horns every year.
3. A noise made by the driver of an automobile to give warning. Honk your horn when you back up.
5. A brass musical instrument with a brilliant tone; has a narrow tube and a flared bell and is played by means of valves. My son plays the French Horn.
