Chimes are ordinarily produced mechanically by the strokes of hammers against a series of bells, tuned agreeably to a given musical scale.

The hammers are lifted by levers acted upon by metallic pins or wooden pegs stuck in a large barrel, which is made to revolve by clockwork, and is so connected with the striking part of the clock mechanism that it is set in motion by it at certain intervals of time, usually every hour or every quarter of an hour.

The chime mechanism is sometimes so constructed that it may be played like a piano, but with the fist instead of the fingers.
