Illuminati (33rd Degree)

The subharmonics that are produced are probably caused by hetrodyning which causes two tones to form a second pair of tones, one being a difference between the two and the other being the sum.

Here's a link about the Theramin, which also uses this property. Of course, the Theramin is an electronic device and the violin is acoustic, but the underlying process applies to both.
