A bell is a simple idiophone percussion instrument. Although bells come in many forms, most are made of metal cast in the shape of a hollow cup whose size form a resonator which vibrates in a single tone upon being struck. The strike may be made by a âclapperâ or âuvulaâ suspended within the bell, by a separate mallet or hammer, or â in small bells - by a small loose sphere enclosed within the body of the bell.
Historically, bells were associated with religious rituals and before mass communication were widely used to call communities together.
