hey guys.... well ill try to make it short.i started playin at 11 (im 16) by my own initiative. I made my parents buy me a keyboard and i just started playing on my own. 3 years later i decided that i needed a teacher so my parents got me one... and another 1 year later they got me a piano. well the problem is i started out self taught and even though ive had teachers on and off since then i hate my playing. Im extremely unsystematic. I can play pieces like the revolutionary study, moonlight 3rd mov, baba yaga from pictures at an excebition, etc decently well but only the first 30 secs... its just pathetic now that i look at it... the songs that i do play untill the end are based on technique that i rarely possess. i am really bad at reading notes since i used my keyboard too much (tells you what keys to press) and i only figure out the rhythm by listening to a recording. i wasted so much time playing to impress people and only recently started realizing how rewarding piano playing can really be if you do ir for yourself. well my question is what can i do to really advance and become a decent piano player? i want to start from the 'beginning'. i was thinking of learing as many Bach preludes as i can this summer... and also doing gammes, but i just dont know anymore? please give me some feedback. i know it's a pretty difficult question to answer but i would appreciate anything.. thanks!
