A bell is a hollow resonator — typically a cast-metal cup or chamber — designed to produce a sustained, characteristic tone when its exterior is struck. Its parameters are: (1) a resonant body (metal, ceramic, wood, or other rigid material) shaped to amplify sound at a preferred frequency, (2) a striker (internal clapper, external mallet, or the bell itself swung against a fixed frame), and (3) a mounting system that allows the body to vibrate freely. The bell persists through casting or fabrication practice passed across generations, and through its embedded role in cultural traditions — from temple and church towers to maritime signals and timekeeping.

Bells are designed and maintained for the purpose of signaling — summoning, warning, marking time, or calling attention. Per Law 8d: the servant (bell) points at the master (signaling). Remove bells and signaling capacity diminishes significantly; the designed purpose of bells is to signal.
