Well everything comes from the scale. So the more you about know about scales the more you know about the modes or whatever. And that's just a scale, it's one long ending sound. So after a while it's just kind of monotonous, so you have to learn how to put other little things in the mode. Like you say, ice cream a la mode, so you just stick a little strawberry or cherry or whatever. It takes some adjusting just to play one thing all the time. And in doing that you have to find different things to play. Even John Coltrane, I mean he broke it up and found other things to play, even though it was based on one sound. But one sound has many sounds in it.
