French Horn

The French Horn is a brass instrument made of tubing wrapped into a coil with a flared bell. You get a single or double French Horn. The double horn in F/B♭ is most often used by players in professional orchestras and bands. Three valves control the flow of air in the single horn, which is tuned to F or less commonly B♭. The more common double horn has a fourth, trigger valve, usually operated by the thumb, which routes the air to one set of tubing tuned to F or another tuned to B♭ which expands the horn range to over four octaves and blends with flutes or clarinets in a woodwind ensemble.
