I am trying to learn Ballade No. 1 op. 23 by Chopin(2 as well, but that's not important to this) I have been playing for about 7 years, and I have been without a teacher for several years. My biggest problem is getting the tempo correct and keeping my hands in time. The slow parts are too fast, and the fast parts are too slow. whenever I try to pick up the pace, I make huge mistakes and/or cannot get my hands to synchronize. I am especially having trouble with(in this recording) 4:03-4:32, 6:59-7:53, and the Coda. How do you get your hands to play in time with each other in the faster sections, while keeping musical integrity?
