Many years ago, when I took my first piano lesson, I realised that it would be more difficult than I had thought. Apart from the fight against trying to find the notes on the keyboard, I felt that there was a physical aspect, which nobody had mentioned so far, and it was starting to affect me.
A few months later, a few professors later too, I found a person who talked about piano learning as a doctor trying to find the best solution for your own problems at the keyboard. That person changed the whole thing and helped me, for seven years, to develop a kind of forensic mind to be able to identify the problem in order to put the right remedy. Those "miraculous" remedies were the piano technique, something that should be taught apart from interpretation, but that must join it at the end of the process of learning a piece of music.
Sometimes it is very difficult to show the student the importance of that technique, most of the time because they just want instant results.
Well, there is where a good professor should work, trying to give the "medicine" with a little of sugar in it, that is, technique within a nice piece of music, where they can enjoy the music at the same time they are solving a crucial aspect of the piano technique. Very often you have to write your own scores, always to please the student taste, trying to avoid those boring books with standard exercises, and make a lesson something desirable, like a new adventure with a happy ending every day. Good luck!
