3 weeks on the same etude. 2 months on the same piece, which I will never really get to play because 1) I can't play it fast enough for it to sound like music and 2) my teacher will not learn the piano part (it's a sonata for viola and piano, so it's not just all me me me). Since lessons don't resume until January 3 I am stuck with these things for another 2 weeks. I am so fucking sick of these. I can't see any point, except maybe it saves him from having to come up with something else for me to do.
I have worked on these so much that I've come out the other side. Anything I have learned from them has been lost.
