 | | Salas reputation as the leading, indeed sole, Trautonium virtuoso was thereafter assured, at least on his native soil, but more than twenty years were to elapse before its eerie sounds reached international ears thanks to a last-minute decision by the master of suspense. |
 | | The original Trautonium was essentially a monophonic instrument: Indeed, it could be described as a state-of-the-art descendant of the Pythagorean monochord a wire stretched across a fingerboard. |
 | | In the Trautoniums case, the depressed wire completes an electric circuit that activates an oscillator, whose tone is amplified and can be altered by means of filters. |
