June 30 Let's Get Theremined

Leon Theremin invented the first electronic musical instrument in 1919. It's named after him. It used the principle of heterodyne down conversion, invented only a year before. Heterodyne conversion is used in every radio in the solar system today, and in the fastest parts of the Internet. Yes, there are several heterodyne converters working right now in your mobile phone.

You have heard the theremin, it's a continuously variable tone common in scifi soundtracks, and occasionally even pop. It's pretty easy to play,

Rob Schwimmer, co-director of The NY Theremin Society, visits Portland for a free short performance and demonstration tonight. And after you can try your hand at the instrument. If you can't make it tonight, Control Voltage has theremins you can stop by anytime to audition.

Theremin demonstration at Control Voltage 3742 NE Mississippi. All ages. 7PM-8 Free
