The Emiriton was an example of a series of finger-board electronic instruments developed in the Soviet Union in the 1930’s, inspired perhaps by Leon Termen’s avoidance of a standard keyboard with his Theremin. Other instruments included V.A.Gurov’s (a former colleague of Leon Termen) “Neo-Violena“(1927) the “Sonar“(1930) and the Volodin’s “Ekvodin” (1931). Designed by A. Ivanov and A.Rimsky-Korsakov, The Emiriton was a originally a fingerboard instrument allowing the use of glissando effects, with later models incorporating a standard keyboard. The Emiriton generated sound from neon-tube oscillators and was able to replicate sounds such as the bassoon, violin, cello and clarinet.

Biographical Information: Andrey Vladimirovich Rimsky-Korsakov
Andrey Vladimirovich Rimsky-Korsakov, grandson of the famous Russian composer,studied at the Leningrad Conservatory and the Leningrad Polytechnical Institute. His combination of musical and technical knowledge allowed Andrey Vladimirovich to work successfully at the Research Institute of Musical Industry organized by Academician N.N.Andreyev. From 1932 he collaborated with the engineer A.A.Ivanov to construct one of the earliest Russian electric musical instruments: the Emiriton. In early 1941, Rimsky-Korsakov moved to the Leningrad Physicotechnical Institute of the Academy of Sciences of the USSR, where he began his investigations in hydroacoustics. In 1942, he joined the Navy and, during the war was involved in designing and testing acoustic mines. After the war, Rimsky-Korsakov returned to his studies in musical acoustics at the Leningrad Electrotechnical Institute of Communication, and later at the Acoustics Institute of the Academy of Sciences of the USSR, Moscow. In 1960, Rimsky-Korsakov established the Department of Electroacoustics and Ultrasonics at the Moscow Mining Institute focussing on acoustical measurements, and noise and vibration control and technological processes of low-frequency acoustic vibrations.
