How the triangle makes its sound

In the Hornbostel–Sachs system, which classifies instruments by how they produce sound, the triangle belongs to the struck idiophones: the body is struck directly – bells, gongs, xylophones and cymbals.

More broadly it is one of the idiophones, where the solid body of the instrument itself vibrates, without strings or a stretched membrane.

Players shape its sound through technique and materials; the resonating body filters the raw vibration, boosting some harmonics and damping others.

From Wikipedia

The triangle, or musical triangle, is a musical instrument in the percussion family, classified as an idiophone in the Hornbostel-Sachs classification system. Triangles are made from a variety of metals including aluminum, beryllium copper, brass, bronze, iron, and steel. The metal is bent into a triangular shape with one open end. The instrument is usually held by a loop of some form of thread or wire at the top curve to enable the triangle to vibrate, and it is struck with a metal rod called a "beater". The triangle theoretically has indefinite pitch, and produces a plurality of overtones when struck with an appropriate beater.
