Stupid Choir Teacher

My perfect plan to get a non-singing part may have failed. I auditioned today and i tried to throw off my singing part by doing it an octive higher so i would naturally sound like crap. But the freakin retards caught me and now i'm upset. When i sang it an octive lower they said I did a good job and i'm just hoping and praying that they were just being polite. And that it actually sucked because if i have to sing a lot in this freakin play someone's gonna die.
