Triangle (musical instrument)

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.[1] While the triangle theoretically has a definite pitch, it is obscured by the overtones that are produced when struck.[2]
