Strictly speaking, electronic music refers to the production and treatment of sounds exclusively by electronic means such as OSCILLATORs, FILTERs and MODULATORs. See: SOUND SYNTHESIS, SOUND SYNTHESIZER.
Electronic music grew out of the activities in Europe in the 1950s of composers at the Cologne and Milan studios of the German and Italian Radios. Independent research in the United States and Canada at about the same time resulted in the creation of studios at Columbia University, the University of Toronto and elsewhere.
Today, 'electronic music' is a general term used to refer to any music produced by ELECTROACOUSTIC or other electronic means.
