A bell () is a directly struck idiophone percussion instrument. Most bells have the shape of a hollow cup that—when struck—vibrates in a single strong strike tone, with its sides forming an efficient resonator. The strike may be made by an internal "clapper" or "uvula", an external hammer, or—in small bells—by a small loose sphere enclosed within the body of the bell (jingle bell).
A bell is a percussion instrument made from a hollow cup-shaped object that produces sound when struck, either by an internal clapper, an external hammer, or a loose sphere inside it. Bells matter because their curved design creates an efficient resonator that vibrates to produce a strong, clear tone when struck.

Bells are usually cast from bell metal (a type of bronze) for its resonant properties, but can also be made from other hard materials. This depends on the function. Some small bells (such as ornamental bells or cowbells) can be made from cast or pressed metal, glass or ceramic, but large bells (such as a church, clock, and tower bells) are normally cast from bell metal.
