“…Here’s a lovely clip of musician/writer/producer Tara Busch shattering a wine glass with her bare voice! Filmed by Maf Lewis.
“How does this happen?” you may ask?
The tone that the glass makes when you lightly strike it is its natural frequency. If you then sing a note that is at that EXACT same pitch, the glass will vibrate as well.
