Bell

Bell

A small, flattened bell in a clock, watch or alarm that is struck with a hammer. In a repeater-watch, bells are replaced by gongs which are strips of tempered steel, firmly secured at one end. The hours are struck on a low note; the quarter-hour is struck on two notes, one low and one high.
A chime uses three notes.
