Yes, I read that article/blog yesterday and perhaps that was one of the things that got me thinking that much the difficulty is due to the fact that music practice occurs without the teacher present.
In Chua's WSJ article, think of how much of that epic battle could have been avoided if the problem had occurred when the teacher was present!
At an advanced level, one can't expect even the brightest and most talented child to figure it out by themselves. Neither can you expect the (non-musician) parent to do so.
DD and I have our struggles, but in a similar situation we would simply continue to muddle along for the rest of the week and then discuss the problem with the teacher at the next lesson.
