Oskar Salas last Mixturtrautonium

The Trautonium is a monophonic electronic musical instrument developed about 1929 by Friedrich Trautwein in Berlin at the Musikhochschule's radio research section, the Rundfunkversuchstelle. Instead of a keyboard, its manual is made of a resistor wire over a metal plate, which is pressed to create a sound. This instrument, however, is a replica of Sala's Mixtur-Trautonium. It was built in 1988 at the Deusche Telekom AG Business Academy and was the last Trautonium-model, Sala played on. Picture: schnepp renou © Musikinstrumenten-Museum SIM PK.
