The object in the museum catalogue
This rhythmicon was made by Leon Theremin in New York, New York, about 1931. This instrument is the earliest electronic rhythm machine. It produces various drumbeats or rhythms using a unique mechanism of light sources and rotating perforated-wheels. A keyboard is used to produce a repeated single rhythmic note. Multiple keys produce overtone series of notes. Amplification with a loudspeaker produces the audible rhythmic output.
The instrument was used by Joseph Schillinger in his 1940-41 recordings. Joseph Moiseyevich Schillinger (1895-1943) was a composer, music theorist, and composition teacher, known for the Schillinger System of Musical Composition.
