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).
Apart from typical technical repertoire, essential excercises were recommend by the greats are Liszt and Brahms books.
However,look at Graham Fitch videos about technical training, he has few good sentences of which pianists almost forgot and play technical pieces like a crazy for months with zero to non effect.
I am right now reading Gieseking book (which is btw write towards advanced pianists as stated by the author), but there is a ton of knowlege.
He say that techcnical development goes alon with practicing normal pieces with proper attitude and analysis. But yes, it's godlike virtuoso telling to us mortals waking up on the ladder...
but there are very good advices. Book seems tiny, but there is almost non unnecessery wirting, everything is right to the point, which ends in tons of knowlege and examples. Mind opening book.
He says, that if you understand what you want to play, and practice it properly, than techniqe will come by itself. I do not agree with this 100%, but definitely there is piano school which agrees with it.
