Hey guys, so I'm auditioning for a Jazz Guitar program at my university. I have playing guitar for 10 years, but I'll admit I haven't been practicing too much for the last couple years and I am a bit rusty. The audition requires me to do a written theory evaluation, which I'm comfortable I can do well on as long as I review. But it also requires me to play two contrasting pieces. It also says the pieces should be RCM level 8 or higher if possible. Unfortunately, I know very little about jazz, as well as how to find out RCM grading for the pieces, so I'm pretty confused right now. I read another thread with someone asking for suggestions on what to play for a guitar audition, and all of the pieces had brass instruments playing lead. Does this mean if I choose those songs I'm supposed to play the trumpet/sax lead part on guitar? Or are there good jazz pieces that can be chosen where the original track has a guitarist playing lead? Also, any general tips/ advice would be great if anyone else has gone through this in the past. (I'm at York U in Toronto, just on the small chance that anyone reading this has auditioned here) Sorry for the dumb questions, I just didn't want to contact the department with these questions in fear of looking bad and jeopardizing my chances of them passing me even more Thanks in advance!
