I'm using the Mozart Sonata No. 8 in A Minor
I can barely get through the piece memorized without taking certain parts slow or having a train wreck. Should I forfeit? Go and audition to gain experience (negative included)? Try to get a refund? Tell me your opinion!
I agree with dima: back out immediately. You know the piece is not performance ready so why place yourself in a situation where a train wreck is bound to occur? You will get enough negative experiences in life even when you are fully prepared. Why create a totally unnecessary one?
