The theremin (〔(【引用サイトリンク】title=Theremin World - Theremin FAQ )〕 ; originally known as the ætherphone/etherphone, thereminophone〔The London Mercury Vol.XVII No.99 1928〕 or termenvox/thereminvox) is an early electronic musical instrument controlled without physical contact by the thereminist (performer). It is named after the Westernized name of its Russian inventor, Léon Theremin, who patented the device in 1928. The instrument's controlling section usually consists of two metal antennas that sense the relative position of the thereminist's hands and control oscillators for frequency with one hand, and amplitude (volume) with the other. The electric signals from the theremin are amplified and sent to a loudspeaker. The theremin was used in movie soundtracks such as Miklós Rózsa's for ''Spellbound'' and ''The Lost Weekend'' and Bernard Herrmann's for ''The Day the Earth Stood Still'' and as the theme tune for the ITV drama ''Midsomer Murders''. This has led to its association with a very eerie sound. Theremins are also used in concert music (especially avant-garde and 20th- and 21st-century new music) and in popular music genres such as rock. == History == The theremin was originally the product of Soviet government-sponsored research into proximity sensors. The instrument was invented by a young Russian physicist named Lev Sergeyevich Termen (known in the West as Léon Theremin) in October 1920 after the outbreak of the Russian Civil War. After a lengthy tour of Europe, during which time he demonstrated his invention to packed houses, Theremin found his way to the United States, where he patented his invention in 1928. 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. During the 1930s Lucie Bigelow Rosen was also taken with the theremin and together with her husband Walter Bigelow Rosen provided both financial and artistic support to the development and popularisation of the instrument.〔Glinsky pp. 127–128〕 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 NKVD agents (preceding the KGB),〔(''Tell Me More'', BBC, h2g2 project, Undated ).Accessed:05-20-2008.〕 taken back to the Soviet Union and made to work in a ''sharashka'' laboratory prison camp at Magadan, Siberia. He reappeared 30 years later. In his 2000 biography of the inventor, ''Theremin: Ether Music and Espionage'', Albert Glinsky suggested the Russian had fled to escape crushing personal debts, and was then caught up in Stalin's political purges. In any case, Theremin did not return to the United States until 1991.〔Glinsky pp. 185–187, 329〕 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 that were intended to be assembled by the customer. Moog credited what he learned from the experience as leading directly to his groundbreaking synthesizer, the Moog. Since the release of the film ''Theremin: An Electronic Odyssey'' in 1994, 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 garnered excellent reviews.〔(MRQE – Movie Review Query Engine – Theremin ), see also the rare 100% score at (Rotten Tomatoes )〕 Theremin kit building remains popular with electronics buffs; kits are available from Moog Music, Theremaniacs, PAiA Electronics, and Jaycar. On the other end of the scale, many low-end Theremins, some of which have only pitch control, are offered online and offline, sometimes advertised as toys. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Theremin」の詳細全文を読む スポンサード リンク
