i just got in my college's jazz big band for guitar and i am really nervous because the last big band i was in was in high school and it was at a level that was much lower skill level than now. how would you prepare for something like this before you have had your first rehearsal?
before the first rehearsal, there is only 1 way to prepare, which is to freak the heck out for the entire time until the first rehearsal. this will unfortunately have no effect on the amount of time you will freak out when you get there, which will be limited to exactly 20 minutes no matter what
