I have a problem , now that I cannot theoretically play Chopin Etude (Winter Wind).I was practicing it for almost 6 months and I am almost 3/4 of the whole piece. The trip to China interrupted my learning.As I came back,I realized that I cannot do it anymore. Why does it have to be that way?
but one thing is certain, there is only one way to play it.
Forgetting how to play a piece after a break is normal. There is nothing wrong with that. However, it will come back much faster than when you initially learned it. Actually, forgetting parts can be a good thing. It would be an indicator of which parts you need to pay more attention to. Also this will exercise your brain's ability to recall the piece from long term memory.
