I know this music is too hard for me, but I'd like to work up to it. The largest problem with it for me right now is the left hand 16th notes. I would like to know how I can effectively play the left hand notes? http://sheethost.com/sheet/ci6RSp
Something that has helped me immensely with this is visualization. You can look at the keyboard, but try to IMAGINE how your hand should move. Make sure that your hand position between the two octaves doesn't change too much, and that your hand is moving fluidly (not jerky). Try to maintain good wrist technique. This sort of thing is hard for every pianist to learn, but gradually will become easy over time.
