I played a little bit when I was a child and then briefly in my teens. Didn't advance too much, though. About a year ago I set a goal of "really" learning how to play. I've been studying between 1 and 3 hrs, 4, 5 days per week. I did a of reading around here and other places and it seems that the recommendation is that we ditch Hanon, Czerny, Pischna, and the likes and learn technique from repertoire. I managed to go through a lot of the easy stuff that kids play (Tchaikowsky's Children's Album, Burgmuller and what not). Then I learned about 7 or 8 of Chopin's easier waltzes, but I realize that I don't play them very well. I believe I don't have the technique to play them correctly. I figure that if I insist on them I'll be able to develop my technique as I practice, but what is happening is that because I don't have proper technique I end up developing bad habits that are hard to correct when I catch them. So my question is: what kind of repertoire could help me develop good technique? Or should I select a some material targeted at the development of technique instead of learning from real music?Unfortunately, I can't afford a teacher and don't have the time during the day to work with one (I work all day and I practice play late at night).
