did't practice for concert; i can sightread; there are 7sharps, i have a solo part, there are at least 5 key changes, time signature is 5/4 first page is filled with 32nd notes and triplet runs, i have no rest at all, the piece is in presto, the score is so messy i can't read the notes, my stand partner is gone so i have to turn pages on my own, and i have the melody all throughout the piece.
