“To attempt to describe how music pervades and flavors a life feels a little like an invasion of privacy, even if the privacy is my own. Listening to music,...is finally the most inward of acts--so inward that even language, even the language of thought, can come to seem intrusive...After all these procedures the unbreachable mysteriousness of music remains intact. The book can never be more than an interruption. Afterward, the listening begins again, to generate, in turn, other and completely different books.”
