Karen:
There are a couple of things i do not like from my teacher:
1-
HE DOES NOT PLAY IN FRONT OF ME.

That is, he makes me play and corrects me (he has a very good ear and gives sound advices), but i am unable to make him play (except for some very simple pieces we play 4 hands).
As a matter of fact, i suspect he cannot really play the pieces i am studying (he does not seem a very good sight-reader, by the way). And i am talking about BEGINNER pieces (most advanced being "Fur Elise").
What better way to show how something should sound than to play it? I have no doubt that he can very quickly learn those beginner pieces, but he does not spend the time because HE DOES NOT NEED TO PLAY THEM!!!
2- He does not seem to know a true repertoire for beginners...he insists on giving me Hanon, Czerny, Beyer, and all that boring stuff. So, i have to negociate to make some of those excercises and some the pieces i enjoy to play (that are at my reach).
3- He does not teach me any harmony theory (i am in my 6° month). I have no idea what chord i am playing, or why this chord is usually followed by that other chord, etc etc
Of course, i am just emphasizing those aspects i do not like. There are also some positive aspects i really appreciate, like:
1- Very good ear (he does not miss a single of my frequent mistakes).
2- Very attentive during the class.
3- He is very experienced.
4- He insists on the musicality side of the piece.
5- He is a perfectionnist. He is never trully satisfied, wanting allways to improve some aspect of the piece, an approach i really like.
But, after all, i did not say i was planning to leave him very soon !!!
