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 grea… - Charles Mingus

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't play half as much to satisfy myself. As a youth I read a book by Debussy and he said that as soon as he finished a composition he had to forget it because it got in the way of his doing anything else new and different. And I believed him. I used to work with Tatum, and Tatum knew every tune written, including the classics, and I think it got in the way of his composition, because he wasn't a Bud Powell. He wasn't as melodically inventive as Bud. He was technically flashy and he knew so much music and so much theory that he couldn't come up with anything wrong; it was just exercising his theory.

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.

I think my own way. I don't think like you and my music isn't meant just for the patting of feet and going down backs. When and if I feel gay and carefree, I write or play that way. When I feel angry I write or play that way — or when I'm happy, or depressed, even.
Just because I'm playing jazz I don't forget about me. I play or write me, the way I feel, through jazz, or whatever. Music is, or was, a language of the emotions. If someone has been escaping reality, I don't expect him to dig my music, and I would begin to worry about my writing if such a person began to really like it. My music is alive and it's about the living and the dead, about good and evil. It's angry, yet it's real because it knows it's angry.
