What a wonderful idea, right?
What happens if we apply it more broadly?
Well, in Australia, which tried this out, it meant that more men were hired than women in Australian Public Service. Which, of course, was tragic, and means that it will be abandoned. We can't let equality upset the quotas for diversity, after all.
You might get more men. And, as a warning, if you don't get the mix you want in the orchestra, that might change back, too.
