PHOTO-THEREMIN

The Photo-theremin is a bit different than a traditional theremin in that it is controlled by light. This particular Photo-theremin is different than most because it uses 2 photo-transistors instead of a photocell. Because it uses light it actually responds differently with different types of light. For example, with a traditional light bulb it produces a square wave sound like a more harsh traditional theremin, and under a flourescent light the sound is more noisy and thin. It also responds different to effects lights, such as strobes. What you get is a unique sound and more playability because you can vary the types light into two different photo-transistors for amazing results! The range of the Photo-theremin is also much greater than any I have heard it ranges from extreme lows to highs that actually extend above the audible range!
