Most major university music departments have professors that are willing to accept private students that are younger than college age.If you want to actually start on a college degree, I know that the Performance Diploma (BMUS without the general education) program can be started in highschool at the Vancouver Academy of Music. The piano professors there are Prof. Lee Kum-Sing, Prof. Amanda Chan and Prof. Lorraine Ambrose. Prof. Lee regularly sits on many international juries, including the 1995 Chopin Competition in Warsaw. He has also produced many students who have gone on to win prizes internationally in the Leeds and Paderewski Competitions, as well as national competitions like the former CBC Young Performers. Prof. Chan also teaches at UBC and is one of the most active collaborative pianists in British Columbia. She herself has won prizes in most of the competitions in Canada, ccan be regularly heard on CBC and the VSO. Prof. Ambrose has taught students who have won national and international competitions. Many of her former students are pursuing international careers as soloists, chamber musicians and new music specialists.
