Mikrophonie is the title given by Karlheinz Stockhausen to two of his compositions, written in 1964 and 1965, in which “normally inaudible vibrations . . . are made audible by an active process of sound detection (comparable to the auscultation of a body by a physician); the microphone is used actively as a musical instrument, in contrast to its former passive function of reproducing sounds as faithfully as possible” (Stockhausen 1971a, 57).
