Tubular bells

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.
