In 1953–1954, the WDR composers began building sounds with additive synthesis, a process of layering and recording sine tones using generators and magnetic tape. The young composers, including Stockhausen, Goeyvaerts, Koenig, Gredinger, and Pousseur, believed that this meticulous work, carried out in accordance with their own serial, proportional schemes, would yield complete sonic control. Much to their disappointment, the sounds they produced were unsophisticated. Moreover, the process was tedious and time consuming. They turned to each other to voice these frustrations, discussing their perceived failures and collaborating on experimental solutions. Eventually, the composers relinquished total control, and instead found technical shortcuts based on the scientist Meyer-Eppler’s teachings on psychoacoustics, or perception of sound. The composers’ initial additive synthesis compositions were in some ways aesthetic failures, but useful ones nevertheless. Through trial-and-error, composers learned more about both the studio machinery and human perception. Their successes and failures also reached far beyond the studio, as composers such as Ligeti translated electronic inspirations into compelling orchestral music.
