Electronic music

Electronic music, music composed of sounds and manipulated, created solely on electronic equipment. Concrete music uses recordings of natural sounds as the basis for composition, and works mixing both approaches are called “tape music.” Experiments with electronic composition began as early as the 1890s, but widespread production began only after World War II, as universities and broadcasting authorities in many countries began setting up studios to encourage this use of modern technology. Edgard Varèse, John Cage, and Karlheinz Stockhausen have produced important works in this field.
