Léon Theremin playing an early theremin

The theremin (originally pronounced [teremiːn] but often anglicized as [ˈθɛɹəmɪn] [1]), or thereminvox, is one of the earliest fully electronic musical instruments. It was invented by Russian inventor Léon Theremin in 1919, and it is unique in that it was the first musical instrument designed to be played without being touched. It consists of two radio frequency oscillators and two metal antennae. The electric signals from the theremin are amplified and sent to a loudspeaker.

To play the theremin, the player moves his or her hands around the two metal antennae, which control the instrument's frequency (pitch) and amplitude (volume). The theremin is widely associated with "alien", surreal, and eerie-sounding portamento, glissando, tremolo, and vibrato sounds, due to its use in film soundtracks such as Spellbound, The Lost Weekend, and The Day the Earth Stood Still. The theremin is also used in art music (especially avant-garde and 20th-century "new music") and in popular music genres such as rock and pop.

Similar electronic instruments, such as the Ondes-Martenot also use the principle of two heterodyning oscillators, but the Ondes-Martenot is touched while it is played.

History

The theremin was originally the product of Russian government-sponsored research into proximity sensors. The instrument was invented by a young Russian physicist named Lev Sergeivich Termen (known in the West as Léon Theremin) in 1919, after the outbreak of the Russian civil war. After positive reviews at Moscow electronics conferences, Theremin demonstrated the device to Bolshevik leader Vladimir Lenin. Lenin was so impressed with the device that he began taking lessons in playing it, commissioned 600 of the instruments for distribution throughout the Soviet Union, and sent Theremin on a trip around the world to demonstrate the latest Soviet technology and the invention of electronic music. After a lengthy tour of Europe, during which time he demonstrated his invention to packed houses, Theremin found his way to America, where he patented his invention in 1928 (US1661058). Subsequently, Theremin granted commercial production rights to RCA.

Although the RCA Thereminvox, released immediately following the Stock Market Crash of 1929, was not a commercial success, it fascinated audiences in America and abroad. Clara Rockmore, a well-known thereminist, toured to wide acclaim, performing a classical repertoire in concert halls around the United States, often sharing the bill with Paul Robeson. In 1938 , Theremin left the United States, though the circumstances related to his departure are in dispute. Many accounts claim he was taken from his New York City apartment by Soviet agents, returned to the USSR and made to work in a sharashka. However, Albert Glinsky's 2000 biography Theremin: Ether Music and Espionage suggests he fled to escape crushing personal debts, and was subsequently caught up in Stalin's political purges. In any case, Theremin did not return to the United States until 1991. [2]

After a flurry of interest in America following the end of the Second World War, the theremin soon fell into disuse with serious musicians, mainly because newer electronic instruments were introduced that were easier to play. However, a niche interest in the theremin persisted, mostly among electronics enthusiasts and kit-building hobbyists. One of these electronics enthusiasts, Robert Moog, began building theremins in the 1950s, while he was a high-school student. Moog subsequently published a number of articles about building theremins, and sold theremin kits which were intended to be assembled by the customer. Moog credited what he learned from the experience as leading directly to his groundbreaking synthesizer, the Minimoog.

Since the release of the film Theremin: An Electronic Odyssey in 1994 (one year after the death of Léon Theremin), the instrument has enjoyed a resurgence in interest and has become more widely used by contemporary musicians. Even though many theremin sounds can be approximated on many modern synthesizers, some musicians continue to appreciate the expressiveness, novelty and uniqueness of using an actual theremin. The film itself has gathered excellent reviews. [3]

Today Moog Music, Wavefront Technologies, and tVox manufacture performance-quality theremins. Theremin kit building remains popular with electronics buffs; kits are available from Moog Music, Theremaniacs and PAiA Electronics. Rare antique RCA theremins continue to be in demand, fetching tens of thousands of dollars at auction.

Operating principles

The theremin is unique among musical instruments in that it is performed without being physically manipulated by the operator. The musician stands in front of the instrument and moves his or her hands in the proximity of two metal antennae. The distance from one antenna determines frequency (pitch), and the distance from the other controls amplitude (volume). Typically the right hand controls the pitch and the left controls the volume, although some performers reverse this arrangement. Additionally, some newer theremin use a volume dial and have only one antenna.

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.

To control volume, the performer's hand acts as the grounded plate of another variable capacitor. In this case, though, the variable capacitor takes the place of the variable resistor that is usually used to control the volume of audio equipment. The distance between the performer's hand and the volume control antenna determines the capacitor's value, which regulates the theremin's volume.

Performance technique

Easy to learn but notoriously difficult to master, theremin performance presents two challenges: reliable control of the instrument's pitch with no physical guidance (no keys, valves, frets, or fingerboard positions), and minimizing undesired portamento that is inherent in the instrument's microtonal design.

Pitch control is challenging because, unlike most musical instruments, the theremin generates tones of any pitch throughout its entire range, including those that lie between the conventional notes. While some other instruments share this feature, particularly the stringed instruments, those instruments use several (typically four) separate strings to express the instrument's full range of pitches, and positions on the fingerboard corresponding to specific notes become familiar to performers. In the case of the theremin, the entire range of pitches is controlled by the distance of the performer's hand to the pitch antenna in mid-air, and over relatively short range of distances. Very precise control of hand position coupled with an excellent sense of pitch is required.

Also, the theremin's continuous range of pitches lends itself to glissando playing, which is often inappropriate to the piece being performed. Skilled performers, through rapid and exact hand movements, minimize undesired portamento and glissando to play individual notes and can even achieve staccato effects. Small and rapid movements of the hands can create tremolo or vibrato effects.

Although pitch is governed primarily by the distance of the performer's hand to the pitch antenna, most precision thereminists augment their playing techniques with a system called "aerial fingering", largely devised by Clara Rockmore and subsequently extended by Lydia Kavina. It employs specific hand and finger positions to alter slightly the amount of capacitance relative to the pitch antenna to produce small changes in tone quickly and in a manner that can be reliably recreated.

An alternate and controversial "hands on" technique is called "angling" in which the pitch control hand is actually set on the top of the theremin which violates the "no touch" creed of traditionalists. It employs changing the angle of the hand and fingers to alter the pitch and repositioning the hand if the pitch interval is too large for "angling". By touching the instrument, the effect on pitch of extraneous body movement is dampened. This permits the use of steady pitches without vibrato and without remaining perfectly still.

Equally important in theremin articulation is the use of the volume control antenna. Unlike touched instruments, where simply halting play or damping a resonator silences the instrument, the thereminist must "play the rests, as well as the notes", as Ms. Rockmore observes. [4] Although volume technique is less developed than pitch technique, some thereminists have worked to extend it, especially Pamelia Kurstin's "walking bass" technique.

Skilled players who overcome these challenges by a precisely controlled combination of movements can achieve complex and expressive performances, and thus realize the theremin's musical potential.

Some thereminists in the avant-garde openly rebel against developing any formalized technique, viewing it as imposing traditional limitations on an instrument that is inherently free form. These players choose to develop their own highly personalized techniques. The question of the relative value of formal technique versus free form performances is hotly debated among thereminists. Theremin artist Anthony Ptak uses antenna interference in live performance.

The theremin in use

In art music

The theremin is a popular instrument among avant-garde and new music artists because of its perceived freedom from traditional compositional strictures. It also persists as a classical instrument, and is occasionally used in jazz. Classical composers who have written for theremin include Bohuslav Martinů, Dmitri Shostakovich, Percy Grainger, Christian Wolff, Mortimer Browning, Anis Fuleihan, Joseph Schillinger, David Simons, Mark Steven Brooks, Olga Bochihina, Caspar Johannes Walter, Alan Hovaness, Edgar Varese, Nicolaus Richter de Vroe, Michael Hirsch, Juliane Klein, Vladimir Nikolaev, Moritz Eggert, Iraida Yusupova, Robert C. Ehle, John Haussermann, Friedrich Wilckens, Isidor Achron, Jorge Antunes, and Vladimir Komarov.

The most recent major classical composition utilizing the Theremin is Lera Auerbach's ballet The Little Mermaid, a 3 hour production featuring the theremin as the mermaid's voice throughout. The Royal Danish Ballet commissioned Russian American composer Lera Auerbach to create a modern rendition of this fairy tale. It was choreographed by John Neumeier and premiered on April 15, 2005 with Lydia Kavina as the theremin soloist.

Russian musician Lydia Kavina is widely regarded as the greatest living theremin virtuoso. She is a distant relative of Léon Theremin and was his protégé. Her repertoire consists primarily of classical and neo-classical compositions, many of which were written for the instrument. Many thereminists have studied under Ms. Kavina, including German thereminists Barbara Buchholz and Carolina Eyck, English thereminists Bruce Woolley and Miss Hypnotique, and Japanese thereminist Masami Takeuchi.

Pamelia Kurstin is a New York-based thereminist whose eclectic styles and innovations continue to expand the instrument's range. She performs solo in the classical and jazz idioms, as well as in ethnic and avant-rock music with the band Barbez.

Armen Ra specializes in performing ethnic Armenian music. Other performers of note include American Eric Ross, Canadian Peter Pringle, and Eri Ii of Japan. Within improvised music UK based Beatrix Ward-Fernandez is one of the more notable practitioners from the younger generation of experimentalists.

Project: Pimento, based in San Francisco, is a well-known theremin band on the west coast of the United States. The music ensemble consisting of theremin, vocals, guitar, bass, and drums is the world's only theremin-fronted lounge music band. Robby Virus, the band's founder and theremin player, was featured on the soundtrack to the movie Hellboy (2004).

Throughout the theremin's use in film music from the 1940s to the 1960s, its sound was equated with the bizarre and alien. Because of Clara Rockmore's professed distaste for such projects, the thereminist most commonly enlisted to perform anything from haunting melodies to eerie sound effects was Dr. Samuel Hoffmann, whose performances can be heard most prominently in the soundtracks for Spellbound (1945) and The Day the Earth Stood Still (1951).

In popular music

Theremin sounds have been incorporated into many popular music songs from the 1960s through the present.

Theremins have also been used in live concerts and in the studio by artists such as Phish, Pixies, The Flaming Lips, Tripod, The Octopus Project, Chris Funk (The Decemberists), The Polyphonic Spree, Fishbone, Jean Michel Jarre, Jon Spencer Blues Explosion, Charlie Clouser (Nine Inch Nails), Natalie Naveira (Lendi Vexer), Bill Bailey, Nikki Sixx, Pere Ubu, Keller Williams, One Ring Zero, The Damned (by Dave Vanian), Gandalf Murphy and the Slambovian Circus of Dreams, Russian duo Messer Chups, Patrick Wolf, DeVotchKa, Roy Harter, Pram, The Phenomenauts and Man or Astroman?.

A theremin solo was featured in live versions of the song "Whole Lotta Love," by the band Led Zeppelin, the instrument being played by the band's guitarist, Jimmy Page. The instrument was played by keyboardist Rob Schwimmer on the Simon and Garfunkel album Old Friends: Live on Stage. Rock band Supergrass uses a theremin in their song "Richard III", on the album In it for the Money.

The Lothars are a Boston-area band whose CDs have featured as many as four theremins played at once.

Alison Goldfrapp uses a portable theremin in her live performances for the song Train; she plays the instrument in a decidedly sexual manner, using her legs to manipulate it.

Marilyn Manson uses a theremin, played by band member Madonna Wayne Gacy, in the song "Dope Hat." This can be seen in the video for the song.

Les Claypool's Fancy Band uses a theremin, played by Gabby La La in the song "Of Whales and Woe." It is seen during this song and others on the DVD Fancy.

Tiamat uses a theremin, played by its guitarist and vocalist Johan Edlund, on the album A Deeper Kind of Slumber.

One of the most persistent theremin myths is that The Beach Boys used one in the 1966 recording of "Good Vibrations". Brian Wilson did request that a theremin be included in the studio orchestra for this recording, but neither the instrument nor a musician to play it were available at the time. Instead, Paul Tanner was brought in with his homemade device called an Electro-Theremin, which featured mechanical controls that could mimic the theremin sound. For concert appearances, a slide-controlled oscillator was designed and built for Wilson by Robert Moog.

Another myth is that the theremin is featured on the album In the Aeroplane Over the Sea by Neutral Milk Hotel. The instrument used is in fact the bowed or singing saw (played by Julian Koster) which has a sound similar to that of a theremin but which is in fact an idiophone and not electronic at all. It is featured most noticeably in the background of the title song "In the Aeroplane Over the Sea."

In movies and movie soundtracks

The Russian Dmitri Shostakovich was the first composer to include parts for the theremin in orchestral pieces, including a use in his score for the 1931 film Odna. While the theremin was not widely used in classical music performances, the instrument found great success as the 'eerie' background sound in countless motion pictures, notably, Spellbound, The Red House, The Lost Weekend, The Spiral Staircase, The Day the Earth Stood Still, The Thing (From Another World), The Ten Commandments (the 1956 DeMille film), Ed Wood, and Mars Attacks!. The theremin is used as a melodic solo instrument, rather than as a sound effect, in the soundtracks of Raw Deal, Hellboy, Bartleby, and Monster House. The DVDs for Ed Wood and Bartleby both contain short features on the theremin.

A theremin appears and is played in the Argentine movie La Niña Santa.

Actor Jerry Lewis plays a theremin in the 1957 Paramount film The Delicate Delinquent. The instrument belongs to a crackpot inventor whose appearance resembles that of Leon Theremin.

A theremin is heard when the sword sings in the Bugs Bunny cartoon Knighty Knight Bugs.

The theremin is sometimes employed by comedian Bill Bailey in his music themed comedy shows, usually in reference to the theremins association with science fiction and horror film music from the 1950s and 1960s.

It is often believed that the theremin was used for the soundtrack of Forbidden Planet. In fact, a ring modulator was used to create the 'electric tonalities'. A beautifully designed version of the theremin was seen and heard in the movie Captain Nemo and the Underwater City.
