Instruments commonly part of the percussion section of a band or orchestra. These three groups overlap heavily, but inclusion in any one is sufficient for an instrument to be included in this list. However, when only a specific subtype of the instrument qualifies as a percussion instrument, only that subtype is listed here.
A cymbal is a common percussion instrument. Often used in pairs, cymbals consist of thin, normally round plates of various alloys. The majority of cymbals are of indefinite pitch, although small disc-shaped cymbals based on ancient designs sound a definite note (see: crotales).
A gong (from Malay: gong; Chinese: 鑼; pinyin: luó; Japanese: 鑼, translit. ra; Khmer: គង - Kong; Thai: ฆ้อง Khong; Vietnamese: cồng chiêng) is an East and Southeast Asian musical percussion instrument that takes the form of a flat, circular metal disc which is hit with a mallet.
The tambourine is a musical instrument in the percussion family consisting of a frame, often of wood or plastic, with pairs of small metal jingles, called "zils". Classically the term tambourine denotes an instrument with a drumhead, though some variants may not have a head at all.
When classifying instruments by function it is useful to note if a percussion instrument makes a definite pitch or indefinite pitch. For example, some percussion instruments (such as the marimba and timpani) produce an obvious fundamental pitch and can therefore play melody and serve harmonic functions in music.
The triangle is an idiophone type of musical instrument in the percussion family. It is a bar of metal, usually steel but sometimes other metals such as beryllium copper, bent into a triangle shape. The instrument is usually held by a loop of some form of thread or wire at the top curve.
