I have been playing this piece for quite some time now, and I feel as though the last step that is preventing me from playing this piece well is the tension that I feel each time I strike the pattern with the two consecutive octaves. I sometimes go in and out with being relaxed and then eventuyally tense up again. I can't really grasp what I am missing here, but maybe some others have had a similar problem. I have tried to understand the relaxation concept more, but I literally can't "touch" on it yet. The legato phrasing is something I am good at, but trying to flop my hands around to hit octaves is something completely different. I want to say that I have successfully completed a Chopin Etude and I don't want to back away from this one without giving it my all.
