In such systems, when the antenna is removed, the oscillator moves up in frequency. 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.
The classic analog theremin design incorporates vacuum tubes or discrete transistors in the oscillators, mixers, and amplifiers. Those components shape the harmonic coloration and the overall timbre of the tone produced. The instrument’s tone, linearity, and sensitivity are influenced by the types of capacitors and inductors used, differences in the physical layout of the circuit components, and even the ambient environmental temperature. The theremin is an eerie-sounding instrument that you can play by using your hands to disturb an electromagnetic field created by its two antennae. Though many people see it as a novelty primarily used to create horror-movie soundtracks, you can play many styles of music on the theremin. If you learn to orient your body properly, identify key notes, and position your fingers to manipulate melody, you’ll be on your way to making your own beautiful music with this unusual instrument.
- The first time a new player approaches a theremin, his performance is more likely to sound drunken and atonal than distinguished or adept.
- Music researchers estimate that there are more than 1,500 musical instruments in the world.
- The mixer produces the audio-range difference between the frequencies of the two oscillators at each moment, which is the tone that is then wave shaped and amplified and sent to a loudspeaker.

With only two antennae to manipulate, the theremin seems like it would be a breeze to play. In the hands of a master, the theremin can sing with the precision, vibrato and depth of a seasoned mezzo-soprano. When operated by a novice, on the other hand, it produces little more than earsplitting blats and squawks. In 1967, Paul Tanner invented electrotheremin, an instrument that mimics the sounds of the theremin, and is responsible for the high-pitched sound on “Good Vibrations” by the Beach Boys. Below, we’ll list three of the most important players in theremin history.
Silvia Alonso-Pérez ( ) is a professor in the department of industrial engineering at the University of La Laguna in the Canary Islands, Spain. Endlessly eerie and magnificently mysterious, the theremin has inspired musicians, scientists, makers and artists for generations — and will, no doubt, continue to do so for generations to come. With no complicated chords or fingerings, at first glance, the theremin seems like it should be a cinch to play. So why do many enthusiasts consider it the world’s most difficult instrument? The theremin was the product of Soviet government-sponsored research into proximity sensors.

With royalty-free sample packs like Theremin Explorations with hYrtis, you can take lyrical melodies, layered arrangements, and effected atmospheres created with the instrument and use them in your own productions. Roughly four decades before Stevie Wonder and the Doors began incorporating electronic synthesizers into their music, another electronic instrument took the world by storm. 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.

Rockmore worked with Theremin to further the possibilities of the instrument, and their time together led to the inventor falling in love with her. Thereminists appear to play their instruments almost like invisible strings, employing techniques such as vibrato on held notes. Although skilled players might make it look easy, playing it requires great musical coordination and serious technical ability.
Were it not for its two prominent antennae, the RCA theremin would have seemed at home in almost any parlor. Most frequently, the right hand controls the pitch and the left controls the volume, although some performers reverse this arrangement. Some low-cost theremins use a conventional, knob-operated volume control and have only the pitch antenna. Various pop and rock stars have had their dalliances with the instrument, including Simon and Garfunkel, Led Zeppelin’s Jimmy Page and The Rolling Stones’s Brian Jones – and the instrument’s influence on electronic music was considerable. Contrary to popular myth, the theremin does not appear on the Beach Boys’ 1966 single Good Vibrations or anywhere on the soundtracks to Doctor Who or Star Wars. But it does have a big role in Clangers, the children’s TV series about a family of mouse-like creatures who live on a small moon-like planet.
Use the sound of the theremin in your own music
As the hand approaches the antenna, the capacitance increases, which changes the frequency of the alternating current in a circuit and results in a higher pitch. 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.
The theremin works by harnessing the power of electromagnetic interference. The human body is a capacitor; our bodies conduct electricity, and can store electric charges (as you might know if you’ve ever tried to pet your fluffy cat after shuffling your feet along a carpet while wearing socks). Learn about the Shepard tone, a popular auditory illusion that tricks your brain into thinking a sound is always rising or falling in pitch. Although volume technique is less developed than pitch technique, some thereminists have worked to extend it, especially Pamelia Kurstin with her “walking bass” technique24 and Rupert Chappelle. In fact, the theremin is notorious as one of the hardest instruments to master. Start a conversation with us and an ever-growing community of other music creators via the Splice Discord.
Theremin, electronic musical instrument invented in 1920 in the Soviet Union by Leon Theremin (also called Lev Termen). It consists of a box with radio tubes producing oscillations at two sound-wave frequencies above the range of hearing; together, they produce a lower audible frequency equal to the difference in their rates of vibration. Pitch is controlled by moving the hand or a baton toward or away from an antenna at the right rear of the box. Harmonics, or component tones, of the sound can be filtered out, allowing production of several tone colours over a range of six octaves.
Variations on a Theremin
Theremin’s first prototype for his device consisted of a wooden box that housed electronic circuits, a vertical antenna for pitch control, and a pedal for volume control. He soon replaced the pedal with a horizontal loop antenna, which resulted in the design that is commonly used today. The instrument’s pitch circuitry includes two radio frequency oscillators set below 500 kHz to minimize radio interference.
- “Make music with the wave of a hand! Sound like an opera star! So easy, anyone can do it!” Such were key selling points of the first commercially available theremin.
- 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.
- As fate would have it, meeting Theremin resulted in her adopting this new instrument, and with time, becoming its most recognizable face thanks to her controlled performances.
- He offers kits for sale as well as detailed instructional articles, including schematics, on constructing vacuum tube powered theremins.

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 https://p1nup.in/ the oscillator is greatest; farther from it, the effective inductance is larger, and fractional change on the oscillator is reduced. Playing the theremin requires precision and a trained ear, so previous musical experience helps a lot. A classically trained violinist, she quit playing when tendinitis affected her bow arm. As fate would have it, meeting Theremin resulted in her adopting this new instrument, and with time, becoming its most recognizable face thanks to her controlled performances.
Today, hackers and musical tinkerers of all kinds use these same principles to create all manner of Theremins and Theremin-like devices. Since a simple fluttering of fingers is all it takes to make noise on a Theremin, it seems like the Theremin would be a cinch to play. Find out why many enthusiasts consider the Theremin the world’s most difficult instrument in the next section. Theremins and theremin-like sounds started to be incorporated into popular music from the end of the 1940s (with a series of Samuel Hoffman/Harry Revel collaborations)47 and has continued, with various degrees of popularity, to the present.
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.
