I only want to give a metaphysic for my music.

Then, after the war it was impossible to travel, after so many years of Hitler and Stalin.

Perhaps the better word is emotional yes, I am an emotional man

I don't use old music.

I continued to study Math and Physics on my own, but one and a half years later I realized that I did want to be a composer, and after that I never changed my mind.

In my piano concerto I developed this polyphony to much higher complexity

Yes, fractals are what I want to find in my music.
