Sadie: Yes, and tone quality. He would blow one note for all day long.
Eric: I've seen him blow one note on the saxophone for WEEKS at a time. And I'd be out in the yard working, and I'd go in and say "There is no more key on that saxophone but that one?" And he'd play it, then he'd put it on his tape recorder, and he'd listen to it, and he'd say, "Dad, it's got to be right." And I'd say, "It sounds right to me." "No, it's not right yet."
