WLU?
I just checked Performance major @ U of T a few days back (I was thinking of double majoring.. then I realized you can't do artsci and music at the same time)And to audition for performance major you need AT LEAST grade 10 RCME level pieces.I'm not sure what laurier is like, but I assume it would be around the same difficulty.
Yes, that is one of the schools I plan on auditioning for.
The musicianship skills such as singing Bach chorales, is something you most likely will study in a musicianship course in your 1st year of uni. I don't think they will be too hard on you during the audition with musicianship exercises. Some people already have the ability to do this stuff and wish to exempt the course requirement, thus there is a test for that.
