One part of the piece Polyrhythmoform1, composed by Andrey Smirnov in 2016, commissioned by CTM (Berlin) for the project Technosphärenklänge#2 and performed live with the 3rd version of the instrument, restored by Andrey Smirnov.
The Rhythmicon (aka Ployrhythmophone) is the very first optoelectronic rhythm machine. It was developed by Leon Theremin in 1931-32 in the USA according to the order of the American composer Henry Cowell, who suggested to strictly map rhythms to ratios from the harmonic overtone series. It was a reaction on the idea proposed by Charles Seeger: that just as the pitch relations of polyphonic music can create harmonic dissonance, polyrhythm could be thought of as "rhythmic dissonance." According to Leland Smith' research one Rhythmicon was built for Henry Cowell in 1931 and it worked not well. Sometime in the middle 30s Cowell left it at the Department of Psychology at Stanford University, where it was finally discarded and thrown around 1938. Another instrument was built in 1932 for the conductor Nicolas Slonimsky, who was intended to use it in his concerts, but it never happened. In the early 40s Slonimsky sold it to the composer Joseph Schillinger. In 1966 the heirs of Schillinger gave the instrument to Smithsonian Institute (USA). The third instrument was built by Leon Theremin at Moscow State Conservatory in the early 1960s.
