A bell is a simple musical instrument. Most bells are made of metal. An object shaped like a cup that makes a ringing sound when hit.

he striking implement can be a tongue suspended within the bell, known as a clapper, a small, free sphere enclosed within the body of the bell or a separate mallet.

Bells are usually made of cast metal, but small bells can also be made from ceramic or glass. Bells can be of all sizes: from tiny dress accessories to church bells weighing many tons.

Bells are made to exact formulas, so that given the diameter it is possible to calculate every dimension, and its musical note, or tone. The frequency of a bell’s note in Hz varies with the square of its thickness, and inversely with its diameter. Much experimentation has been devoted to determining the exact shape that will give the best tone. The thickness of a church bell at its thickest part, called the ‘sound bow’ is usually one thirteenth its diameter. If the bell is mounted as cast, it is called a “maiden bell” while “tuned bells” are worked after casting to produce a precise note.
