Would a Musical Triangle of Any Other Shape Sound as Sweet?
The surprising proof of resonance in the open-ended musical triangle could exist in circles and squares too.
For the triangle, researchers captured proof that resonance occurs even with the notched, open corner, and it may occur in other instrument shapes as well. Credit: Risako Tanigawa
WASHINGTON, May 6, 2025 – The triangle is a small instrument made of a metal rod bent into a triangle shape that is open at one corner. While small, its sound is distinct, with multiple overtones and nonharmonic resonance. But what causes the surprisingly powerful sound?
“The triangle instrument produces enchanting and beautiful tones, raising deep and profound questions about the connection between music and physics,” author Risako Tanigawa said. “Optical sound measurement has…click to read more
