Oskar Sala had been a pupil of Friedrich Trautwein, the inventor of the Trautonium. But physicist Sala studied music with Paul Hindemith in 1930 at the Berlin conservatory and also played his compositions for Trautonium. Early on with Trautwein, he composed pieces for Trautonium and performed them with the Berlin Philharmony conducted by Carl Schuricht in 1940.
From the 40's, he dedicated himself to film scoring and helped numerous classics to gain their musical refinements. In 1960, Alfred Hitchcock was unsuccessfully searching for an acoustic environment to his eerie bird scenes until Sala convinced him to use his Trautonium-generated sound-effects.
