One should not count on me to give explanations on this mysterious title.

This score, I announce it however, is rather rigorously serial, although serious analysts will probably find much ease there.

I speak much about series and I apology, but it is that it was the great debate of the Fifties, and I was twenty years old, like electronics was that of the Sixties, like the minimalism was that of the Seventies, etc. Debates in which I was active or through which I passed. And I left from there alive.
