If it means anything, one thing that helps me is recording my music. It takes me much longer to prepare for a recording, but I find the process forces me to remove most of the flubs. It also really makes me listen to my own playing. Though getting rid of flubs/mistakes is hard for anyone (esp me.)
Some will say 4-8 hours a week is not nearly enough, though to be honest, as a busy person, I am lucky if I can get even that. I think I read somewhere once that it takes at least 10,000 hours of practice to become expert in something. At 4-8 hours a week this will take quite a few years
In terms of sight reading, the only thing I could recommend is getting as much music as possible. I find it really important to have sheet music that is easy enough to sight read, yet still fun and enjoyable to play. I turns out the world is full of piano music like this. I personnally like to develop my memorization skills and sight reading skills at the same time.
Anyway, just my 2 cents
Hi! I've played piano for about 2 years. I've never had lessons, just picked up tips here and there, I also have read some off the pianofundamentals.com site.
I can read sheet music, but I am very slow at it. My sight reading is very poor. I mainly just go through pieces I like a few bars at a time, memorizing each hand separately and then putting the hands together. I probably average about 4-8 hours a week practicing.
Over the past few weeks I've read through most of the threads in this forum and must say I've found lots of good information from many of you.
I continue to develop better habits the more I play, but I've noticed even with pieces I practice on for quite some time, I make many mistakes. Usually small mistakes on timing or wrong notes, or almost wrong notes where my finger brushes against the next key over a bit too much. Sometimes bigger mistakes where I stop for a few seconds before picking up again.
Any comments, thoughts, information or anything about weeding out mistakes I would very much like to hear. Or just anything in general that you might think my problems are, like maybe my whole song learning method stinks =p I'd like advice!
