Lucky for him, the Russian leader, Vladimir Lenin, ‘adored’ the invention and made Léon set sail at once, on a world tour, to show off Russia’s newly acquired technology. Soon enough, electronic music found its way all over Europe and the rest of the world, with the theremin at its core.

It was invented a Russian, Leon Theremini in 1928 and is one of the oldest electric instruments in the world. To play it, the player doesn’t require any physical touch whatsoever, instead players’ hand position between two antennas is utilised to create amazing tunes. In the volume-control circuit, one or two high-frequency oscillators are used, whose combined signal is routed first through another nonlinear mixer before being sent to a filter. A band-pass filter is sometimes used instead of a low-pass filter because the former gives the instrument a greater dynamic range and makes the volume response more sensitive to smaller hand motions. Theremins uses the phenomenon with a slight modification, as it holds one plate of the capacitor in its antenna while the other capacitor plate is the musician’s hands, which gives the musician full control of oscillating the current and hence, the tunes. When the musician moves the capacitor plate, i.e. his hand close to the antenna, the plates store more charge, and consequently the current oscillates at a lower frequency; vice versa when he moves the hand away.
By making small rapid movements with the hands, an expert theremin player can generate soulful music. Unlike earlier electromechanical musical instruments, the theremin was conceived from the beginning as an apparatus whose sound would be generated entirely electronically. Working in the laboratory of famed theoretical physicist Abram Ioffe, Theremin had developed an early wireless motion-detection alarm system and a device to measure the density and dielectric constant of gases. Both projects explored capacitance changes in circuits, which led Theremin to notice that the position of his hand in an electromagnetic field affected the pitch of the sound emitted by an electric oscillator. That observation inspired him to create a musical instrument, originally marketed as the etherophone and the thereminvox, that could play melodies based on the performer’s hand position relative to an antenna.

Check out a few of the examples below for more information, or just a bit of easy listening. The instrument itself is a fascinating oddity that’s gained a niche in the offbeat music world. Most remarkable is that it’s an instrument you can play without touching. The thereminist in action resembles a conductor waving his or her hands in the air in front of the instrument, which looks like a podium with two protruding antennae. It may be a bizarre spectacle, but there’s a method to this madness. The reference standard used by both builders and performers to evaluate the tone quality of a theremin is the sound emitted by the first model manufactured by RCA.
The Basics of Playing the Theremin
Demonstrated by the Russian physicist, inventor, and musician Leon Theremin in 1920, the unique device came to carry its creator’s name. It was brought to market by RCA in 1929 and was the first commercially available electronic instrument. Clara Rockmore (1911–1998) a virtuoso performer of the theremin playing the instrument. Below are three of the most prominent players in theremin history and provide a glimpse into this instrument’s past. Of course, you could debate whether the sound being produced is music or noise to your ears, but that is a purely subjective decision.

Silvia Alonso-Pérez ( ) is a professor in the department of industrial engineering at the University of La Laguna in the Canary Islands, Spain. Her research combines engineering with her passion for electronic music. Despite the obscurity and unknown to many, millions of listeners have heard the instrument through popular bands of the 60z and 70s, such as Led Zepplin, The Beach Boys, and the Rolling Stones.
Why People Keep Throwing Sticks at The Stikhokken
- But digital circuitry makes the sound of those theremins more stable and less harmonically complex.
- Analog and digital theremins differ significantly in their tonal character.
- Although it may take years of practice before you master the instrument, some believe the theremin is worth the time and effort.
- Termen also ran his own companies, which were fronts for industrial espionage.
- He was sent to the Gulag in Siberia where he was put to work at a secret laboratory where he created an incredibly advanced bugging device that was used successfully to spy upon British, French and US embassies in Moscow.
The theremin was originally developed in the USSR by researcher Leon Theremin, while he was hard at work developing a high-frequency oscillator capable of measuring electric force through gases. As he experimented, he discovered that he could change the pitch of an audio signal generated by this oscillator by changing the position of his body in relation to the electromagnetic field he was attempting to measure. When your hands alter the theremin’s surrounding electromagnetic fields, the interference causes an audible sound.
- The theremin typically consists of a box with two metal antennas—one vertical and one horizontal.
- Close to the resonant frequency of the antenna circuit, the effective inductance is small, and the effect on the oscillator is greatest; farther from it, the effective inductance is larger, and fractional change on the oscillator is reduced.

- Still, if you’re interested in electronic instruments, synthesizers, and electric circuits, the theremin is a great topic to research, even if you don’t end up trying to play it yourself.
Hollywood composers began to adapt the theremin to create atmospheric background scores for psychological thrillers and science-fiction movies—Music out of the Moon, It Came from Outer Space, The Lost Weekend, The Day the Earth Stood Still, Mars Attacks! After a meeting with Vladimir Lenin, who was at the https://p1nup.in/ time the Chairman of Russia’s new Bolshevik government, Termen was sent across Russia to show off his instrument and promote the electrification of the country. Lenin then sent Termen on a tour of Europe and the USA to showcase Russian technology and his performances received wide admiration. As Termen gathered his fellow scientists around this incredible noisemaker for a demonstration, Termen realized he had a new instrument in front of him.
If the pitch hand is moved between notes, without first lowering the volume hand, the result is a “swooping” sound akin to a swanee whistle or a glissando played on the violin. Small flutters of the pitch hand can be used to produce a vibrato effect. To produce distinct notes requires a pecking action with the volume hand to mute the volume while the pitch hand moves between positions. The theremin is an instrument that typically consists of a wooden box with two antennae; one controls pitch, and the other controls amplitude (loudness).

We uncover the secrets of the phantom fundamental, a spooky audio illusion that has us hearing pitches that may not actually exist. Not long after adapting the device to harness this capability, Theremin had the opportunity to show it off to Lenin, who was so taken with his new instrument that he recruited him to gather intelligence on a US tour.
A theremin-like instrument sometimes called the electro-theremin is used for one of the signature parts of “Good Vibrations” by The Beach Boys. Even if you’re not familiar with the musical instrument called the theremin, chances are you’ve heard its ghostly sound. What’s more, even if you don’t have access to a theremin, that doesn’t need to stop you from incorporating its unique sound into your music.
Termen’s sudden departure aroused controversy and many suspected he was kidnapped by the KGB. In the hands of a master, a theremin will sing with mellifluous precision and the depth of a seasoned mezzo-soprano. Operated by a novice, however, you might beg to Lord invoke his wrath on the perpetrator’s dissonant blats and squawks coming from the insensitive movements of their fingers.
The theremin is distinguished among musical instruments in that it is played without physical contact. The thereminist stands in front of the instrument and moves their hands in the proximity of two metal antennas. While commonly called antennas, they are not used as radio antennae for receiving or broadcasting radio waves, but rather act as plates of capacitors. The distance from one antenna determines frequency (pitch), and the distance from the other controls amplitude (volume). Higher notes are played by moving the hand closer to the pitch antenna. Louder notes are played by moving the hand away from the volume antenna.
With the antenna circuit disconnected, the oscillator is tuned to a frequency slightly higher than the stand-alone resonant frequency of the antenna circuit. At that frequency, the antenna and its linearisation coil present an inductive impedance; and when connected, behaves as an inductor in parallel with the oscillator. Thus, connecting the antenna and linearising coil raises the oscillation frequency. Close to the resonant frequency of the antenna circuit, the effective inductance is small, and the effect on the oscillator is greatest; farther from it, the effective inductance is larger, and fractional change on the oscillator is reduced. The instrument’s controlling section usually consists of two metal antennas that function not as radio antennas but rather as position sensors. Each antenna forms one half of a capacitor with each of the thereminist’s hands as the other half of the capacitor.
Obviously, playing a song with this quirky instrument takes coordination and practice. Termen also ran his own companies, which were fronts for industrial espionage. Theremin also developed a prototype drum machine and an instrument that responded to a dancer’s movements, alarm systems and an electric door opener, but none of his inventions proved a commercial success, and he ended up in debt. When Termen married a young black American ballet dancer, Lavinia Williams, in 1938, his sponsors drew away their support, compounding his financial problems. With his financial and social affairs in tatters, Termen fled back to the Soviet Union leaving his wife behind.
Specifically, the change in capacitance—typically only a few picofarads—changes the frequency of a variable oscillator. That oscillator and one of fixed frequency form the pitch-control circuit. Both oscillators typically consist of a capacitor and an inductor connected in parallel.
Even setting up multiple theremins on one stage can cause problems—since electromagnetic fields aren’t visible, theremins can be finicky to troubleshoot. In 1919, the young Russian physicist Lev Sergeyevich Termen, or Léon Theremin, as he is known in the west, was working on a high-frequency oscillator he built to measure the dielectric constant of gases. When Termen decided to add an audio circuitry to the device so that it emitted an audible tone when it took a reading, he discovered that the machine was not only responding to the dielectric constant of gases but of people around the machine as well. By changing the position of his hands or by moving around the device, Termen discovered that he could make his machine emit strange noises. This amazing instrument is called the Theremin, etherphone or thereminophone.
