Tubular bells (also known as chimes) are musical instruments in the percussion family. Their sound resembles that of church bells, carillons, or a bell tower; the original tubular bells were made to duplicate the sound of church bells within an ensemble. Each bell is a metal tube, 30–38 mm (1+1⁄4–1+1⁄2 in) in diameter, tuned by altering its length. Its standard range is C4–F5, though many professional instruments reach G5. Tubular bells are often replaced by studio chimes, which are smaller and usually less expensive instruments. Studio chimes are similar in appearance to tubular bells, but each bell has a smaller diameter than the corresponding bell on tubular bells.
Tubular bells are usually struck on the top edges of the tubes with a rawhide- or plastic-headed hammer. A sustain pedal may be attached to the instrument to allow damping and un-damping of all the bells at once. Very loud high-pitched overtones can be produced by vibrating the bottoms of the tubes with a violin bow.
