Keyboard (Bell)

(n.)
any of several different devices which permit one person to play all the bells in an instrument by hand, with one key per bell. The key size and arrangement vary according to the mechanism used:
* baton keyboards, found in all traditional carillons and some chimes, have keys that are shaped somewhat like batons, have direct mechanical linkage to the clappers of the bells, and are usually arranged in two rows like the black and white notes of a piano;
* "pumphandle"
(American) or "barrow-handle"
(French) keyboards are found in chimes with direct mechanical actions much heavier than those of carillons, and the handles are usually in a single straight line;
* electric keyboards are similar to those of an organ, and typically use relays to control hammer solenoids, which may strike the bells on the inside or the outside.
Baton keyboards are played by striking a key gently or briskly with the partially-closed fist; pumphandle keyboards are played by grasping a handle and pushing down with a full arm stroke; and electric keyboards are played with the fingers.
