The Trautonium is an early electronic musical instrument invented about 1929 by Friedrich Trautwein in Berlin at his Musikhochschule' music and radio lab, the Rundfunkversuschstelle. The instrument is named after Trautwein.
|Soon Trautwein was joined by Oskar Sala who helped develop the Trautonium until his death in 2002. Sala was a German physicist, composer, and a pioneer of electronic music. In 1948 Sala further developed the Trautonium into the Mixtur-Trautonum:|
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[example needed]. Sala's invention opened the field of subharmonics, the symmetric counterpart to overtones, so that a thoroughly distinct tuning evolved.
