Here are a handful of random music-related links for your browsing this weekend.
Can you shatter a wine glass with your voice?
A human voice can shatter a glass. Every object has a resonant frequency – the natural frequency at which something vibrates. Wine glasses, because of their hollow shape, are particularly resonant. If you run a damp finger along the rim of a glass, you might hear a faint, ghostly hum – the resonant frequency of the glass. Or you can simply tap the glass and hear the same frequency. To shatter the glass, a singer’s voice has to match that frequency, or pitch, and the glass must have microscopic defects.
The Mirror Duet is usually attributed to Mozart, although there is some question about that. If you’re not familiar, it’s a duet where the two players stand facing each other, reading the same page of sheet music. And it works.
I have no idea who Helen Amvroseva and George Shakhnin are/were, and no way to embed this video of them performing Csárdás on trumpet, trombone, and piano. It’s both impressive and funny.
