john sez: I have always been under the impression, that all the adults that were good musicians in my life, that taught, understood the concept that everyone is unique and will learn (best) a certain way specific to them. --- Maybe in your life, but certainly not in the lives of all. This reminds me of a story where a professor with a Doctorate in Music (trumpet) required everyone to change their embrochure and play with the same embrochure as his regardless of how the student played. I think it would be fair to say the professor is good. He has the credentials. Did he appriciate that everyone is unique? I don't think so.
