Is it the case that any good musician can set up as a music teacher or are there courses they can do to teach them about how to teach.
It seems that dd has some really excellent musicians teach her, but it is hit and miss whether she makes good progress. In one of her instruments most of her techniques have come from watching youtube videos I've found. Another is extremely exact on teaching her very precisely what she needs to do. With the latter she is making good progress.
So, before I swap teachers yet again, I was wondering if there is any teaching qualification they may have in music, as I have found that being a good musician does not necessarily make them a good teacher.
