Odd things around the world: Theremin

Theremin is a musical instrument almost unknown by most people, is characterized by a strange sound and different way to play it.
It was created by Léon Theremin (Russian: Lev Sergeivitch Termen), which was a Soviet inventor
At the beginning of his career Léon created weapons of spying for the Russian military, but to see the horrors of war left this life and decided to focus on his true passion, music.
The Theremin was the only instrument not requiring any physical contact to produce music and was, in fact, the first musical instrument designed to be played without contact, it is performed by moving hands in the air to produce sounds used by some "spooky".
