Do Composers Teach Us to See?

Bach hasn't been transformed into cliche or into implicit assumption. But one of the things that artists do, visual or auditory, is they teach people to see or hear. The impressionists are a good example of that because obviously they're works produced riots when they were first publicly displayed. For most people, it's easy to look at an impressionist painting now. It seems it's so embedded in our visual language that there's nothing about it that seems shocking. And I guess part of the question is, do composers teach us to hear? Once we've learned everything they had to say, do we not need their lesson anymore? Right.
