Whereas Schaeffer and Henry were working like samplers, their idea was to capture those sounds which couldn't be serially calibrated because they were too complex in character.

So the ideology was that: use sounds as instruments, as sounds on tape, without the causality. It was no longer a clarinet or a spring or a piano, but a sound with a form, a development, a life of its own.

Well, first I studied piano. I wasn't very satisfied because I though my teachers were dumb... and repressive.

Electronic music used pure sounds, completely calibrated. You had to think digitally, as it were, in a way that allowed you to extend serial ideas into other parameters through technology.
