Joseph Moiseyevich Schillinger (Russian: Иосиф Моисеевич Шиллингер, 1 September 1895 – 23 March 1943) was a composer, music theorist, and composition teacher who originated the Schillinger System of Musical Composition. He was born in Kharkiv, in the Kharkov Governorate of the Russian Empire (present-day Ukraine) and died in New York City.
The unprecedented migration of European knowledge and culture that swept from East to West during the first decades of the 20th Century included figures such as Prokofiev and Rachmaninov, great composers who were the product of the renowned Russian system of music education. Schillinger came from this background, dedicated to creating truly professional musicians, having been a student of the St Petersburg Imperial Conservatory of Music. Unlike his more famous contemporaries, Schillinger was a natural teacher and communicated his musical knowledge in the form of a precise written theory, using mathematical expressions to describe art, architecture, design and (most insistently, and with most detail and success) music.
