People should not feel intimidated by received wisdom. You have to discover it yourself. If I tell you that Armstrong is great, it's meaningless; you have to hear it.

Jazz is for joy. It's for euphoria, it's for emotion, and anguish, and excitement, and all of the joys that great art can produce, and if it loses that, then it's lost everything.

Even my colleagues don't read classic criticism. And my feeling is that if you don't do that then you're not really practicing your craft. That's how you learn how to do it. You don't learn how to write about jazz just from listening to jazz. You learn how to write by reading the great writers and how they worked, the great music critics.

Bing Crosby said that Armstrong is "the beginning and the end of music in America," and he wasn't far wrong.

When I teach criticism, the first thing I say, and this sometimes pisses off younger - I mean, students, is that, opinions are the least part of criticism. We've all had the experience of going with a friend to a movie or a concert and you leave the theater and one of you loved it and one of you hated it, and that doesn't mean that one of you is an idiot. That's the way things work.

If I'm reviewing a record, man, I play that record to death, which is ironic in a way because if I review a concert I feel very confident in myself, certainly at this point, and have for most of my career. You're only hearing it once and then you go to your typewriter and you write the review.

One of the things I always underscore when I teach criticism is that young critics, or would be critics, frequently have this illusion that if they write about music they're somehow part of music, or if they write about movies they're part of movies, or of they write about theater they're part of theater, or write about literature. Writing is a part of literature, we belong the species of literature. If you add all the music reviews together that have ever been written, they don't create two notes of music.
