Her music actually sounds awful. im sure she can play good music too but this subharmonics stuff sounds like how i started, just press down on all the strings and bow. Miri Ben-Ari is much better

Is this to your liking?

Why not? It obviously isn't just your average example of this effect (with two strings at once), but it could certainly be something like a nuanced way in which a single violin string produces two mathematically compatible tones that isn't obvious, but is actually just the same thing.

The violin is acting as a Helmholtz resonator or Helmholtz oscillator -- a container of gas (usually air) with an open hole (or neck or port). The wavelength of the sound produced is much longer than the dimensions of the resonator. Blow on a bottle -- the sound produced has a wavelength of a few meters. For a 1 liter bottle, the frequency is 130 Hz, which is about the C below middle C. So the wavelength is 2.6 metres, which is much bigger than the bottle. When do I get my Nobel prize?

"Adding two sine waves produces a third sine wave with a frequency equal to the difference between the frequencies of the original two."In a linear system, this is absolutely not true. You will however get periodicity in the summed waveform at a frequency equal to the difference, but that does not always mean you will perceive a pitch at that difference frequency. You often don't, for example if you play a major third interval you're not going to perceive the difference frequency as a pitch.Guitar amplifiers are of course generally highly nonlinear :-)

You're right, I didn't word it correctly. You won't get a sine wave, but you will get a wave (of some sort) that contains a frequency equal to the difference.

...sigh. You ruined the internet. Get ready for four more paragraphs of suck from stupidumb.

Interesting. Check out a violin design concept. the squidolin<a class="user" href="http://digg.com/design/Electric_Violin_Design">http://digg.com/design/Electric_Violin_Design</a>hope you like.
