Georgi Eduardovich Conus, French: Georges Conus (Russian: Гео́ргий Эдуа́рдович Коню́с, Georgy Eduardovich Konyus; September 30 [O.S. September 18] 1862, Moscow – 29 August 1933, Moscow) was a Russian Empire music theorist and composer of French descent. He was the eldest of the three Conus brothers, of whom the others were Julius and Lev. He is buried in Novodevichy Cemetery, Moscow. He had a marked influence upon such students as Alexander Scriabin and Reinhold Glière. For a time, much was expected of Georgi as a composer. Tchaikovsky thought so highly of his promise that he obtained for him the Tsar's annual stipend of 1200 rubles awarded to deserving musicians. Georgi did indeed compose songs, a ballet, a cantata, two symphonic poems, and a variety of other instrumental works. None of these have entered the international repertoire, and Georgi ultimately became more and more immersed in musical academics, formulating an abstruse system he called "metro-techtonic analysis" for the scientific measurement of symmetry in musical forms.
