I've been self-taught for about 1.5 years and have had no teacher and very little guidance (other than a friend from school who comments on my expression every so often when he hears me). I feel that I don't use my practice time very effectively, but I don't know what I should be doing. Some forums say scales are good, others say Hanon is good, others say it's better to work on repertoire and let the technique build from there. Right now, I pretty much just practice on pieces in my repertoire, making sure to correct any technical flaws. I'm mostly focusing on Pathétique (which I have to play at a state competition in 2 weeks, yay) and a scherzo, but as the summer progresses, I would like to do some focused, coordinated technique development.
So, what do you think is a good practice schedule? I've dabbled in Hanon, Czerny, and Donhyani, and though they're helpful, I don't think I've gotten far enough into it to reap any significant benefits.
