Anotations

Scope note:

Sets of stationary hanging bells, normally for outdoor use in an open tower chamber or on a high frame, played manually from a keyboard, automatically by clockwork, or electronically by pneumatic mechanism. More extensive than chimes, their range covers two octaves or more, with all but the lowest notes forming a fully chromatic scale. They are typically played with a keyboard, by which keys mechanically activate levers and wires that connect to metal clappers that strike the inside of the bells. They are often housed in the bell tower of a church or other municipal building.
