That's right. And then, by studying you can play one way today and another way the next day, you know? I can, that's why I have so much trouble with the mike sometimes. I can't express myself the way I want to because I don't play entirely stereotype, you know? I play whatever comes to my mind but I can't do it if the mike don't work so I can hear myself. That's why I have so much trouble with the mike. So, and but you still can't play it unless, you must know it on your horn. You can't go beyond your knowledge, see? And if a person is playing and another person is playing, the other guy has more knowledge, it's going to sound better. It's going to sound better. If two guys have the same talent and the same, even a guy was playing a song called "Gut Bucket" saxophone, the guy was playing "Gut Bucket" saxophone and they're both playing the same. The one that has the most knowledge is the one who will sound better because he can take more advantages. So it goes back to the same thing, just study that's all, see? But the young kids are studying now. It's not like it used to be, see? So I took it up when I was 18 and it was rare. It was not many jazz musicians in this school where I went, the New England Conservatory. I took advantage of it only `cause my mother, it was in her will for me to study music, not to study jazz, it was to study classics.
