This may sound dumb, but I am having a hard time deciding what to play, because I have way too many choices. I'm intermediate, and have a ton of pieces that I HALF know. Lots of Beethoven and Schumann, and a good sampling of everybody else. There really aren't many pieces that I have polished to perfection.And when I sit down to play, I have no idea what to do. I'd like to learn ALL of Kinderszenen, and learn it well - not just sort of half know every piece in it except for a few. I'd like to learn Pictures at an Exhibition well enough to pay publicly. And a few full Beethoven Sonatas. Etc. How do you guys do this? How do you keep pieces polished without revisiting the same ones forever and ever? When you polish a piece do you play it again? Do you go back to it on a regular schedule? Or just let it atrophy? Do you ever sit down and play your whole repertoire, just to make sure you still can?I'm wading through about 9 books at this point.
