 Some of these ideas, considered from a purely theoretical point of view (divorced from their context as explanations of particular compositions) drew significant critical fire (Backus 1962, Fokker 1968, Perle 1960). For this reason, Stockhausen ceased publishing such articles for a number of years, as he felt that "many useless polemics" about these texts had arisen, and he preferred to concentrate his attention on composing (Stockhausen Texte, 4: 13).
