I don't see why a professor should have to teach his students what he already knows, or what he knows how to do. This is all the more true for teaching music. Since the professor knows how to do what he knows how to do, since he's already supposed to know the discipline he's teaching, that ought to be enough! There's no reason at all for the students to follow the same path. They shouldn't repeat, they should invent something else.
