Each jazz musician is supposed to be a composer. Whether he is or not, I don't know. I don't listen to that many people. If I did, I probably wouldn'… - Charles Mingus

Now, whether there is feeling or not depends upon what your environment or your association is or whatever you may have in common with the player. If you feel empathy for his personal outlook, you naturally feel him musically more than some other environmental and musical opposite who is, in a way. beyond you. I, myself, came to enjoy the players who didn't only just swing but who invented new rhythmic patterns, along with new melodic concepts. And those people are: Art Tatum, Bud Powell, Max Roach, Sonny Rollins, Lester Young, Dizzy Gillespie and Charles Parker, who is the greatest genius of all to me because he changed the whole era around. But there is no need to compare composers. If you like Beethoven, Bach or Brahms, that's okay. They were all pencil composers. I always wanted to be a spontaneous composer. I thought I was, although no one's mentioned that. I mean critics or musicians. Now, what I'm getting at is that I know I'm a composer. I marvel at composition, at people who are able to take diatonic scales, chromatics, 12-tone scales, or even quarter-tone scales. I admire anyone who can come up with something original. But not originality alone, because there can be originality in stupidity, with no musical description of any emotion or any beauty the man has seen, or any kind of life he has lived.

Each jazz musician when he takes a horn in his hand — trumpet, bass, saxophone, drums — whatever instrument he plays — each soloist, that is, when he begins to ad lib on a given composition with a title and improvise a new creative melody, this man is taking the place of a composer.

It seems so hard for some of us to grow up mentally just enough to realize that there are other persons of flesh and bone, just like us, on this great, big earth. And if they don't ever stand still, move, or "swing," they are as right as we are, even if they are as wrong as hell by our standards. Yes, Miles, I am apologizing for my stupid "Blindfold Test." I can do it gladly because I'm learning a little something. No matter how much they try to say that Brubeck doesn't swing — or whatever else they're stewing or whoever else they're brewing — it's factually unimportant.
Not because Dave made Time magazine — and a dollar — but mainly because Dave honestly thinks he's swinging. He feels a certain pulse and plays a certain pulse which gives him pleasure and a sense of exaltation because he's sincerely doing something the way he, Dave Brubeck, feels like doing it. And as you said in your story, Miles, "if a guy makes you pat your foot, and if you feel it down your back, etc.," then Dave is the swingingest by your own definition, Miles, because at Newport and elsewhere Dave had the whole house patting its feet and even clapping its hands....
