Gerald Strang in the “Cybernetic Serendipity” catalogue of London’s Institute of Contemporary Arts (1968), quoted: “If I write a series of notes and I say this passage is to be played mezzo forte by the oboe, with certain particular kinds of attacks and certain phrasing patterns and certain expressive devices, I am really saying that certain raw data shall be processed and modified through this instrument, coming out as acoustical sound waves.” As in a microphone for amplification or recording, Strang illustrated, music is broken down from acoustical sound waves into electrical voltages and reconverted back into acoustical energy. This job, the computer is extraordinarily qualified to perform.
