Home Kordinalnuju change in creation of tools of such class was brought by possibility to generate a sound by means of electric current fluctuations. From this point on the idea of new music rushed that is called, in air, but еe realisation in that kind in which electronic music to us is known now, has started to be carried out in the late twenties. Till this time, since the beginning of the century, searches went in the tideway of creation of performing electro-tools. So, one of the first experiences the electro-body, under the name "Telgarmonium", constructed in 1906 the American engineer Kahillom and recognised as historians of electronic music for the first prototype of an electronic synthesizer was such (Though the electromechanical grand piano constructed in 1887 by Mr. Hippom was the very first tool, using electric energy. But the principle of extraction of a sound on this tool was mechanical, as well as in a usual grand piano and was not published by means of electric current fluctuations.). "Тельгармониум" weighed 200 (!) Tons, and in effect it only has rather fundamentally shown possibility of creation of musical devices on new principles. However, in 1915, Whether other American engineer of De Forest (by the way known to experts as the inventor трeхэлектродной radio tubes) has made already the electro-tool based on generators and intensifying radio tubes. It was already quite transportable, but, as far as it is known, remained in the unique copy. In 1921 the Soviet engineer Lev Sergeevich Termen (1896 has created, the electro-tool which has received wide popularity under the name "Termenvoks" which in своeм family of performing electromusical instruments is till now непревзойдeнным, thanks to extraordinary thin possibilities of management and in this sense, bearing comparison with such "sensitive" tool as the violin.
