The snare drum
has a crisp untuned sound that is used by the military and in marching
bands. Sometimes called the side drum, the snare drum has two
heads made of skin stretched over a hollow metal frame.
The top head
is struck with wooden drumsticks, and is called the batter-head. The
bottom head, or snare-head, has catgut or metal strings called snares
stretched tightly across it.
The snares produce
a rattling sound as they vibrate against the head. The snare drum
joined the orchestra nearly 200 years ago in the early 19th century.
