Oskar Sala (June 18, 1910 - February 26, 2002) was a 20th century German composer and a pioneer of electronic music. He played an instrument called the trautonium, a predecessor to the synthesizer.
Sala was a pupil of Friedrich Trautwein, the inventor of the trautonium, and studied with Paul Hindemith in 1930 at the Berlin conservatory.
Oskar Sala further developed the trautonium into the Mixtur-Trautonium. The Mixtur-Trautonium allowed for the first time in music history the execution of sounds which had only been known in theory since the Middle Ages, but were never actually playable.
