Maybe what ails the Toronto music scene is too many orchestras, writes Robert Everrett-Green. How about combining them? “Simply put, a super-orchestra of 150 would be large enough to handle the increased schedules of opera and ballet, and to perform a shorter TSO season. That’s how the Vienna Philharmonic functions, as one emanation of a 163-member pool that also provides players for all the ballet and opera performances at the Vienna State Opera.”
