Fantastic things can happen in the music world. Can you imagine that an electronic instrument can be used as a modern laser alarm system that protects museums and banks? Well, that's exactly what Theremin, a musical instrument, was used for in the early twentieth century.
Lev Sergeyevich Theremin (1896-1993), a talented man, a prominent physicist and a wonderful cellist, was born at the right time and place. During his life he had the opportunity to experience worldwide fame, touring around the world, to open the Teletouch Inc. company in America, and then return to Russia, where he was destined to survive the arrests and repressions in Stalin's camps, to work in secret laboratories to create a number of unique inventions, and, after all that, to work in the Moscow Conservatory. And also, at the end of his life, at age 93, he managed to participate at the festival of experimental music in France. Theremin was one lucky man.
He studied at St. Petersburg University at the faculties of physics and astronomy. He also studied cello in the St. Petersburg Conservatory. During the civil war he joined the Bolsheviks. In 1920 he designed a unique electronic musical instrument which he gave his name «Theremin». The sound of this instrument is considered as the synthesis of the human voice, violin, cello, flute, trumpet and other instruments. It has a space timbre that has an almost hypnotic effect on the audience.
In the early 1920s, physicist Léon Theremin was doing research on proximity sensors for the Russian government. He was trying to develop something like a land-based sonar device using an electromagnetic field to detect objects that entered a certain zone. Instead, the scientist came up with a musical instrument. The Theremin was presented as an electric alarm at the VIII World Congress of Electrical Engineering to Vladimir Lenin. Lenin liked the presented invention. He was particularly amused that the alarm device could still play "Nocturne" by Chopin and "Lark" by Glinka. Soon after the Congress the State Bank and the Hermitage were equipped with the Theremin alarm.
Nevertheless this invention became more popular as a musical instrument. Lev Theremin believed that the possibilities of the Theremin most fully revealed while playing "Vocalise" by Sergei Rachmaninoff.
Inside the first Theremins, a circuit of vacuum tubes, oscillators, coils and wires created electromagnetic fields around the instrument's two antennae. Players fluttered their fingers and waved their hands near the antennae to raise or lower the Theremin's pitch and volume. Thus, the sound could reach a range of 3-4 octaves.
The original version of the instrument was monophonic. Later, in 1975, the polyphonic Theremin was launched. The polyphonic Theremin was able to accompany the melody by chords in the tempered tuning system.
Theremin was also used by foreign directors in their movies. For example, Alfred Hitchcock introduced the sound of this instrument with a mysterious tone in "Spellbound". And Gene Roddenberry used the Theremin in his famous "Star Trek" series.
In 2006, Lydia Kavina and Barbara Buchholz jointly organized the international "Touch! Don't Touch!" festival. Four Russian and five German composers wrote Theremin music specially for this event.
