Music's exclusive function is to structure the flow of time and keep order in it. - Igor Stravinsky

The over-publicized bit about expression (or non-expression) was simply a way of saying that music is supra-personal and super-real and as such beyond verbal meanings and verbal descriptions. It was aimed against the notion that a piece of music is in reality a transcendental idea "expressed in terms of" music, with the reductio ad absurdum implication that exact sets of correlatives must exist between a composer's feelings and his notation. It was offhand and annoyingly incomplete, but even the stupider critics could have seen that it did not deny musical expressivity, but only the validity of a type of verbal statement about musical expressivity. I stand by the remark, incidentally, though today I would put it the other way around: music expresses itself.

As for myself, I need music for hygienic purposes, for the health of my soul. Without music in its best sense there is chaos. For my part, music is a force which gives reason to things, a force which creates organization, which attunes things. Music probably attended the creation of the universe.

It is the transcendent (or 'abstract' or 'self-contained') nature of music that the new so called concretism--Pop Art, eighteen-hour slices-of-reality films, musique concrete--opposes. But instead of bringing art and reality closer together, the new movement merely thins out the distinction.
