Expressiveness - I have hard time working the sound - sure, I can play some notes louder or more quiet, but I'm unable to produce full meaningfull sound that I admire. You could say that I'm too absorbed with hitting the right notes instead of playing music.Exercises - I'm not doing any and this is probably bad. The problem is I dont really know which are suitable for me, for how long a day should I do them and how to see if they help me make any progress.Thought process - my greatest concern - sometimes I'm just afraid that my aproach is all wrong and I cant get good the way I'm playing:- When I'm looking at different keys I cant "hear" a sound they produce, its more like I memorize sequences of keys I need to play and I know what I want to hear and when I make a mistake, but it somehow feels like muscle memory training and checking if it matches melody in my head.- I pratice hands separately but when I play them together its like I play melody and make rythm match it. Should both hands be played separately and just "happen" to create a piece together, or is such a "fixing" a good thing? The thing that if wanted to suddenly stop playing with one hand I probably wouldnt be able to continue with the other. Also I have a feeling that the way I play one hand affects the other.- Playing "freely" - when I read score I dont really pay attention to anything but the pitch - I remember melody so I dont need rythm values (I may be that way because of using many guitar tabs in the past)- I tend to memorize pieces, practice them until I'm either satisfied or I think I cant make it any better the way I am now and then move one to something new, usually forgetting the older ones. Is there something wrong with my memory?
