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.

My sisters were going out with artists and poets, and eventually it was the creative world which attracted me.

I wanted to play piano, and that slid quickly into writing - it wasn't enough to play other people's notes: I had to write notes too.

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.

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.
