He was using microtonal intervals and mathematical ratio relationships to create a 12-tone system, another system. I was interested in the entire harmonic series. Now, of course you can't use the entire harmonic series, but I was interested in what you could call an approximation of that system, and seeing what that sounded like. I wasn't particularly interested in, say, the specific relationship between 47 and 21, that didn't interest me. I was interested in what the series had to tell me about structure itself, because it is an organic structure which somehow emerges as a natural system, but at the same time contains all kinds of incredibly interesting structural ideas and patterns.
Humans love to find patterns in everything.
For me, it was like opening up a treasure chest and seeing what was inside it. To me, you couldn't really see what was in that treasure chest if you didn't use the entire system. You couldn't just use a few of the ratios, you had to use them all. I had to stop working with that when I became too infatuated with the mathematical aspect of it. I had never been interested in mathematics before, but the harmonic series taught me what it was, and I realised that this was the deepest philosophy, the seed of all philosophy.
