The instr. are divided into those of definite pitch—kettledrum, tubular bells, glockenspiel, vibraphone, xylophone, marimba—and those of indefinite pitch—triangle, gong, castanets, whip, rattle, anvil, bass drum, ten. drum, side-drum, tabor, tambourine, bongo, and cymbals. Various unusual devices such as iron chains, motor horns, tin sheet, come into the perc. section of an orch.

They are divided into two groups: ideophones, in which the whole object vibrates when struck (such as cymbals and xylophones); and membranophones, in which a stretched skin or membrane vibrates a column of air (this group includes all drums).
