Physics of the Theremin Musical Instrument

It is an electronic musical instrument that utilizes electric field. When it was released for the first time, people were shocked at seeing instruments can be played without touching it. It was incorrectly adjusted to be in the range of 3 octaves and 2.5 octaves. The operation of the theremin is based on beat frequency theory. There are two antennas on each side. Usually the vertical antenna is on the right side and is used to control the pitch. The closer you are to the player the higher the pitch.

In 1920 Leon Theremin (1993) invented a musical instrument of the Theremin. He invented the Russian physicist, the instrument made with vacuum tube and oscillator. In 1927, he was allowed to travel to the United States to promote his tools and spy the Soviets. He returned to Russia at the end of 1938. He was sent to Siberia for a year and returned to Moscow to tackle the design of the aircraft. He later designed several listening devices. It is an early electronic musical instrument with an unusual slide tone. The 1994 film "Thelmin: Electronic Odyssey" features the instrument. Clara Rockmore (1998, 1998, 88), Clara Reisenberg born in Vilnius became a master of art, became the focus of 1998 video documentary.

This is the story of LéonTheremin, but it is also the story of Evgeny Sholpo. The invent invented a musical instrument named after himself - instruments that are playing today also play an important role in the history of electronic music in the 20th century. Sholpo invented the footnote Variophone. This does not mean that Variophone is not worth more attention. It is actually a way to burn electronic music on a 35 mm film in the early 20th century - Sholpo cuts the wave shape on a cardboard disc and then rotates them at the same speed through the hole while illuminating the film. , Creating a "track" will play the original speaker. You can also overlay sound with up to 12 "sounds" per slide. Throughout the 1930s, Sholpo used Variophone to make soundtracks of Soviet movies.
