They wanted to understand the physical properties of the triangle instrument, test assumptions about the contribution of the triangle shape, and capture clear documentation through pictures of the ...

"The triangle is such a simple instrument," he tells NPR's Tamara Keith. "I mean it doesn't even have a name. Its name is its shape. But it's that simplicity that can exacerbate the details in one ...

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 like beryllium copper, bent into a triangle shape.
