this saturday (november 21, 2009) is the region auditions for my region, and well i will be auditioning, but recently, well all this week, my slurs and what not to one of the songs havn't been coming out properly. i have been having a really hard time with that. and while i play, within 20-30 minutes, my face feels all tense and tight. i try stretching out by saying the vowels, saying "how now brown cow" and "unique new york" but that still doesnt work... this is wierd, this has never happened to me before... what could be causing it? and what should i do? my auditions are the day after tomorrow!!!!
