I was practising a newly-acquired soprano sax this morning and hit a rather impressive high D which I sustained.

Suddenly there was a terrific explosion in the kitchen. A one-pint glass had shattered into little pieces none bigger than 1/4 inch. My wife says the individual fragments continued to vibrate furiously for a while afterwards.

I've heard of shattering glass with your voice and found the following on the Net: "The likelihood of the glass shattering increases with the Q value for the resonance of interest. You can tell what the resonant frequencies are by just hitting the glass with a fork (I do this at parties all the time) and the Q value would be determined by the length of time the tone the glass makes takes to decay till you cannot hear it any more."

I know about the G-spot on a soprano (that's where Kenny plays) but don't have a clue about Q value or resonance of interest.

The glass hadn't been in a microwave and was last used about 2 hours before. It had no cracks or chips.

Could the sax have shattered it?
