Triangle (instrument)
From Wikipedia, a free encyclopedia written in simple English for easy reading.
The triangle is a musical instrument with three sides and curved corners. Sometimes there is a corner which the metal is not joined. This is so different tones can be emitted.
To hold it you need to hold a string above the triangle and when you hit the metal, it vibrates and makes a sound.
Depending on the size of the triangle, the sound will vary.
