Yeah, to get it all in because they couldn't reach it. Duke, on the other hand, I'll quote my piano teacher at Bush Conservatory. She was a classical pianist and didn't know anything about jazz, conceptually, but she did say that he knew more about keyboard harmony than any living person. Now of course this was many years ago. I wasn't too sure of what she meant until I began to study what he did. Because so many people think a pianist is a person that plays, you know lots of little trills or lots and lots of heavy rhythm, or a combination. I'm talking about early concepts now of jazz. Whereas Duke looked upon the piano as an orchestral instrument. And you know once in a while he'd play an arpeggio. But he wasn't known for whooping around all over the notes. He made every note important. My piano teacher said "he knows how to get from here to there with the least commotion..."
