No, it's not a new anti-anxiety medication. I just learned about this AMAZING instrument called a theremin. It's got two antennas and you move your hands in between the antennas, but never touch them.
Taken from wikipedia:
The theremin uses the heterodyne principle to generate an audio signal. The instrument's circuitry includes two radio frequency oscillators. One oscillator operates at a fixed frequency. The other is a variable frequency oscillator, the frequency of which is controlled by performer's distance from the frequency control antenna. The performer's hand acts as the grounded plate (the performer's body being the connection to ground) of a variable capacitor in an L-C (inductance-capacitance) circuit. The difference between the frequencies of the two oscillators at each moment generates a beat frequency in the audio frequency range, resulting in audio signals that are amplified and sent to a loudspeaker.
Now watch this dude play one.
I want one but a top of the line one is like 400 bucks. Still cheaper than a nice traditional instrument. They are supposed to be easy to play but hard to master.
