Play relaxed, controlled to produce desired sound, is there really a moment when you could say that is all taught to you by one teacher or any group of teacher for that matter? I like to play in a manner that takes into account my own two hands and my own mind not someone else's or some preconceived ideology of mastery. It seems to me that unavoidably it is a journey filled more with self discovery accompanied with a dash of good advice. A clashing of ideas tested through your experience base, a world of limited unchanging solutions and a number of arbitrary answers which morph and change depending upon the angle it is viewed from.
Isn't it important that a good teacher makes you aware and sets you in the right direction and allows you to question and test improvement? There's really no end to this all is there?
In any case, what I learned from my teachers was more important than technique or musicality. Learning about who I am as a musician, what I can achieve and how to set achievable targets of all sorts, much more valuable.
