None, for the simple reason that I know next to nothing about the way professional orchestras are run on the management side. For starters, I've never understood why a symphony orchestra needs a management and board not hired and controlled entirely by the musicians themselves, not the other way round. The musicians ARE the orchestra and they should be in total control of its destiny.Are we being hopelessly naïve and idealistic here? No doubt. But that doesn't make us wrong, does it.
