If you know it, you should know it well enough that you won't need to practice much to get it back up to par. Don't worry about it, and just keep practicing your tone/technique exercises on picc. I assume by the sheer number of pieces in your "book" that you are counting all the band/other ensemble music you've played before, in which case the vast majority is probably not very challenging, so why freak out over playing something you already know you can play?

You have all weekend! Play long tones, scales, arppegios. Play through ALL your music. Go to the library on Sat and chek out a bunch of books and sight read through everything!

Spend SOME time with a metronome. On and off. Helps keep you from speeding up or slowing down like mad.

If you get nervous, no worries. Just have fun. Once you put your foot forward enough times the nerves go away somewhat.

Good luck! Do your best.

i hoenstly can't help you on that but i do wish you the best of luck from the bottom of my heart

is that your piccolo in your avatar?

there is a reason you BD doesn't like them. if you want to get good at the piccolo, then don't buy one of them. simply put, they are toys.

No, simply put they are junk. Summer is absolutely right. If you want to play picc well, don't bbuy one of those unless you are going to turn it into a lamp.

I had a blue piccolo and it, well, died within a couple of months. Luckily, my parents bought me a new one that's not colored.
My advice: no colored instruments.
