Triangles

A triangle is a triangular-shaped percussion instrument, usually made of steel. The triangle is hung from a thin string or wire so that it resonates freely. A blow with a metal mallet causes vibrations that create the characteristic sound of a triangle. The intensity and length of the tone can be influenced by the force of the blow and where the mallet lands. In the 18th century, the triangle became a popular instrument in European orchestral music, where its pure and bright tone added sparkle and liveliness to compositions. Today, the triangle is used in various musical genres, from classical to jazz to contemporary popular music.
