I have come to the conclusion that I have no idea how to approach different types of pieces. Using this etude as an example, it isn't that the piece is too difficult, it's just that I find I'm not learning it fast enough. Serperating the hands it's very easy to play, but putting them together it gets jumbled, to the point where I can't even pay attention to dynamics. Now I know with practice I can easily change this, it's just how would I go about learning it fast and efficiently. I always take an approac of learnign a certain amount of measures during one practice session but I just don't know what I'm doing. Some help please and thanks in advance.
