Definition

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. [formal: campana | substrate: behavior | horizon: hours | explicit: yes | epoch: 0.01]

Why it is in scope

A human-made hollow resonator — typically a cast-metal cup or chamber — struck to produce a sustained tone. Built to persist through manufacturing practice and cultural tradition as an instrument of signaling, timekeeping, and ritual.

    A bell IS a specific kind of instrument — a struck idiophone (per Hornbostel-Sachs classification) that produces sound by the vibration of its own body. Per Law 9: a competent speaker calls a bell 'an instrument.' Files against nearest kind instrument.

    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.
