That brings me to my point: to play an instrument without knowing what you're doing can be damaging because you incorporate bad techniques that become so ingrained that it becomes a huge struggle trying to get rid of them to play properly.

Uh . . . what's the point again? Do you really think anyone disagrees with you about this? What's this have to do with whether or not a teacher is a fraud or whether musicians that can't read music fluidly are damaging our culture?

I'm still curious about how you explain the seemingly contradictory statements you've made in this discussion.
