Hi Arty,
Are you getting anything out of your lessons? From what you've said your teacher seems a little un-supportive and a little vague on certain things but I cant give any advice unless I know what she's like when teaching, does she give obvious and not so detailed comments? Is she merely observing or actually teaching you ways of practicing, learning etc..? Personally I feel that for progressive and effective lessons, the student and the teacher should have a good relationship and the teacher should be supportive while the student should appreciate and respect the decisions or advice the teacher gives... Do you communicate well with her? Is she a difficult person?
She encourages me to play a lot of music. When I do something wrong, she'll say, "Why do you do this?" If I don't play my phrases well enough, she'll throw in comments like "Are you typing? You should make the music speak. Practise your left hand/right hand more" If I ask her how to make good phrases, she'll answer "You know how to make phrases."
Mainly, I play for her, she observes and throw in comments like " I don't understand your rhythm... this is unmusical...you should know how to practise..."
If the phone rings, she'll check it or sometimes she'll scribble something on her appointment book or disappear to another room for a moment.
A lot of times, I listen to several recordings and try to copy the way they make phrases.
She is sensitive. Once, after playing a new piece for the first time, I sort of said, so, this is the opening section and she got really upset, saying "Of course I know this piece very very well, you don't have to tell me!"
So, usually, I play in the lessons and get feed back from my teacher, go home and try to fix things up by listening to recordings, reading books, the web, magazines etc...
