Today I am going to talk about Theremin. Theremin originally known as the aetherphone/etherophone, Thereminphone or termenvox/thereminvox. It is an instrument played without touching the instrument. professor,  Leon Theremin who patented the device in 1928. The controlling section usually consists of two metal antennas which sense the position of the player’s hands and control oscillators for frequency  with one hand, and amplitude volume with the other, so it can be played without being touched. The electric signals from the Theremin are amplified and sent to a loudspeaker.

History of Theremin

The theremin was originally the product of Russian government-sponsored research into proximity sensors. Later In 1922,  Lev Sergeyevich Termen, better known in around the world as Leon Theremin. He invented many different devices, but it is the instrument that bears his name that has assured his memory in the collective minds of musicians, engineers..

How to play

The Theremin is almost unique among musical instruments in that it is played without physical contact. The musician stands in front of the instrument and moves his or her hands in the proximity of two metal antennas. The distance from one antenna determines frequency pitch, and the distance from the other controls amplitude volume. Most frequently, the right hand controls the pitch and the left controls the volume, although some performers reverse this arrangement. However, it is easy to learn but difficult to master, Theremin performance presents two challenges: reliable control of the instrument’s pitch with no guidance (no keys, valves, frets, or finger-board positions), and minimizing undesired portamento that is inherent in the instrument’s continuously-variable-pitch design.

Where does it used?

Theremins are popular instruments among avant-garde and new music artists because of their perceived freedom from traditional compositional structures. It is also performed as a classical instrument, and is occasionally used jazz improvisation. Jimmy Page of Led Zeppelin used a variation of the Theremin minus the loop during performances of “whole Lotta love” and “no quarter ” throughout the performance history of Led Zeppelin is one example of Theremin use. Led Zeppelin.

And here is the video, that shows what kind of sound comes out of Theremin and how do they play it without touching it.
