Critical evaluation was transformed into understanding, and criticism became not an act of judgment but of comprehension. - Charles Rosen

For Beethoven, music was still shape, realized and inflected by instrumental sonority: other realizations may be as absurd as arrangements of the Hammerklavier, for example, always are, but the musical conception takes precedence over its realization in sound. The sonority serves the music. For Schumann, however, as for Chopin and Liszt, the conception was worked out directly within the sonority as a sculptor works directly in clay or marble. The instrumental sound is shaped into music.

When I was a small child, The New York Times received every new creation of Igor Stravinsky with hostility, but even then I knew, like everybody else, that he was the greatest living composer-and I knew it even without having heard much Stravinsky or even any of the more recent works at all. It is a mistake of music historians to rely too much on journalists and music critics to assess a composer's reputation, as we generally find a certain delay in their transmission of the more influential professional judgments.

Liszt has never needed revival; his music has always been an important part of the concert repertoire. Nevertheless, he has appeared to need rehabilitation.
