This points out to me the difficulty of taking piano "class". Students are different, the curriculum has to be the same.
For example, I soldiered through John W. Schaum pre book with my Mother, then about half of book one with my private teacher, then she bought an "everybody's favorite music" book and we took off playing stuff that was fun. By contrast, I did every exercise in the Edna Mae Berman books, one a week or sometimes two weeks when I didn't get it. The mechanical tricks of piano, I wasn't able to make those up, I had to grind through the curriculum.
But there are other students who weren't well controlled that missed some things at the most elementary level, and are playing badly at level 8 and never realize what is wrong. A friend of mine never got rhythm down, it interfered with his emotions. He was too impatient for his teacher. Well, my opinion is, you play rhythmically at first until you know the piece, then add emotion to it. When I hear this person play, it is just a big hash to me, even though I hear some right notes in there.
And bar band players that play totally by ear, some of them make a lot more money than I do. But there are things I can do that studied classically that I've never seen them even try.
what the classical curriculum didn't do well when I was young, was teach how to play pop music off a lead sheet. This is the commercial kind of "by ear". the Records and CDs are so different from the lame pop music arrangements they sell at the music store, it is night and day. Playing what people want to hear with their beer is an art to itself.
Good luck, and have some patience, but not too much IMHO.
