So I was wondering how long should a piece take to be played with control (not preformence level) so that you know the piece is not too easy or too difficult for you?And then when should you move on to another? Should all pieces get to preformence level?
Including a bunch of pieces that do not stress me out has made me so relaxed that my technique has improved just as a result of the lack of tension.
Plus there are so many amazing pieces out there that are technically easy (lots and lots of great Schubert pieces that the notes can be sight read but there's so much within them)
