@harpbloke the classic theramin circuit uses a beat frequency oscillator.
early metal detectors used the same system to give audio alerts to the operator through the metal affecting the frequency of a coil.
just like tuning a guitar-if one string is not quite in tune to the next-you hear the difference between them-you know that wah wah wah sound when its close but not quite on.
so if one is 440hertz and the other is 441 hertz you hear the 1 hertz between.
The theremin was NOT used in "Good Vibrations."

I had read that someplace. Looked it up tonight. Wikipedia has "Good Vibrations" and mentions that Wilson used an electro-teremin.

cool-did you know you can do metal detection with a theramin circuit?

thats the beat frequency.
