The bombard is a small, double-reed instrument, the length one would expect for its key. Some 15th century religious sculptures and paintings depict the bombard as the instrument of the devil.
The bombard is usually used to accompany the bagpipe but it has also been used in some orchestral works and in concerts with the organ on account of its tone and musical quality. Bombards are still used in some celtic music. They are quite loud, despite their small size. They are best used outdoors; their tone is high and penetrating.
