I have just finished a session, practising the last movement. My left arm bicep muscle is hurting badly -I think it might have something to do with the bit where the arms cross -I may be tensing up too much -my right arm and hand is ok. This is very depressing. When I played this when I was much younger, I had no pain at all -then I didn't have the technique -now I have the technique in some respects -I don't have the relaxation -I don't know.
I feel right now, like giving up playing altogether. I guess I won't though -I will learn some easier pieces.
Starstuck5, it’s interesting issue: whether continue learning a difficult piece, which is not to one’s apparatus yet, or give it up. I afraid that the reasonable answer is to give it up, at least that is how they advise in the diligent theory books. I never followed that advice myself, though. On the contrary, once I went even against the advice from a friend, professional musician, who had listen to my early efforts in learning an Oscar Peterson solo and said that I just should not learn the piece. That only ignited me on. That very time I just returned to learning piano, bought a DP, and never had a piece memorized through all my life. (The result after three years of gnawing and pausing with it is here:
. Not a big deal for a pro, but at least it is an achievement for myself.) I have been taking chances, but at the same time try to be fully aware of the bad consequences and be ready to pay for my chosen way (not with money but with my time and effort). Odds as a rule are against you, too many obstacles. But if you are not in a hurry and make step at a time there is no reason why you may not achieve the goal some distant day. Of course, there should be easier pieces to learn in your repertoire to keep a reasonable balance. A very difficult piece is an extreme after all in the learning routine. Much depends on your point of view on the learning and your attitude. I look at the Appassionata not only as a prize to reach at the end, but also as a way and means to learn piano playing. I find it more interesting to develop my apparatus on real music obstacles rather than scales and technical exercises, the very thought was mentioned in the CC’s book. Therefore I for one did not placed any time limits on learning the Appasionata, learn it for two years by now without excessive pressure on me and with relevant time share, and it does shift on after all little by little. No annoyance, but patient waiting, if you may keep that way.
Someway that resembles the question asked by a stranger if he/she should start learning piano. Basing on the odds, one should not even try

. The same as it is not worth to climb a steep mountain. It is even dangerous for life/career, isn't it? Most people will give it up too soon. But still we keep trying… Just be aware of the truth and handle it with care.
