Our sensuous appreciation of the world and of the works created by man has, no doubt, a biological foundation, one shared by all human beings, but that is no use to us when we try to evaluate a Bach fugue or a Dostoevsky novel-or even the simple experience of a landscape, as our delight in the view of a mountain or a waterfall is also determined by the traditions of our culture. The coexistence of different criteria of judgment is, in any case, by now a fact of life. Beethoven cannot be judged or even understood by the standards of Mozart, however much he may have continued them, nor Berg by the standards of Wagner or Richard Strauss, nor Elliott Carter by the values of Ives and Stravinsky.

If getting used to music is the essential condition for understanding, it is hard to see just what purpose is served by writing about it. A few experiences of listening to a symphony or nocturne are worth more than any essay or analysis. The work of art itself teaches us how to understand it, and makes the critic not merely parasitical but strictly superfluous.

It is not, however, the unfamiliarity or strangeness of a work or of a composer's manner that is a bar to understanding, but rather the disappearance of the familiar, the ongoing disappointment of the expectations and hopes fostered by the musical tradition in which we have grown up.
