Campanology Word of the Day: Clapper
A violin is a lovely instrument, but to hear its vibrating soul, it must be played with a rosined bow. A marimba, that most percussive of keyboards, cannot sound without at least one mallet. So too is a bell reliant upon a striking agent: the clapper.
The clapper hangs inside a bell, swinging back and forth to make a bell ring. A clapper is composed of a metal shaft terminating in a solid sphere. It is this sphere that strikes the inner sound bow to send reverberations throughout the bell – giving us those rich, resonant tones.
