Home Evgenie Aleksandrovich Murzin (1915-1970) in the manuscript "Aesthetics of electronic music" wrote that "материализация qualities of a sound in tools - very much an important point of development of musical art. The part of expressive means and еe приeмов in this case is formed directly by founders of the tool (so music traditional in определeнном sense was formed темперированным by a clavier)". From this position qualitatively new step were works of a Dr.Sci.Tech. Evgenie Aleksandrovich Sholpo (1891. Having got acquainted with system Shorina of an optical recording of a sound at cinema, Sholpo has decided to construct the device on which it would be possible to draw a sound. It was a brilliant idea opening a way to essentially new direction in music. Thus 1929 when E.A.Sholpo has created the first-ever electronic synthesizer of a sound named it "Variafonom" and composer Arseny Mihailovich Avraamov (1886-1944) became the major mark in the history of electronic music has removed an artificial soundtrack. On this tool the graphic representation was translated in a sound. Depending on the drawing form the timbre, height, dynamics varied. It is necessary to tell that process of reproduction demanded an expense of a considerable quantity of time, but всe it was compensated by possibility of transfer of the plan the composer, passing executors. The author and the executor merged in one person, and music was created by it in directly sounding kind in full conformity to a plan of the composer.
