" Music doesn’t have a single home. It “hovers between two worlds.” (I can practically hear Schopenhauer murmuring his assent.) Different types of music, John continues, require different kinds of listening. Wagner is easy. “The music is sensuous to the point of being like a drug rush.” Beethoven and Mahler and Brahms are trickier. “You feel that you are trying to understand what another person is trying to communicate directly to you. Wagner talks to you about something. Beethoven, Mahler, and Brahms talk to you. That is the difference. "
