Tubular bells (also known as chimes) are musical instruments in the percussion family. Each bell is a metal tube, 30–38 mm (1¼–1½ inches) in diameter, tuned by altering its length. Its standard range is from C4-F5, though many professional instruments reach G5 (see photo). Tubular bells are often replaced by studio chimes, which are a smaller and usually less expensive instrument. 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 sometimes struck on the top edge of the tube with a rawhide- or plastic-headed hammer. Often, a sustain pedal will be attached to allow extended ringing of the bells. They can also be bowed at the bottom of the tube to produce a very loud, very high-pitched overtone.

Tubular bells have been popularized in western culture by the song "Carol of the Bells",^{[citation needed]} and the Mike Oldfield album Tubular Bells and its sequels, the latter best known as the opening theme from The Exorcist.^{[citation needed]}

The tubes used provide a purer tone than solid cylindrical chimes, such as those on a mark tree.
