Some young artists have a kind of naive idea that presenting their vision to the world will almost automatically lead to success. When you think about it, though, it's clear that you won't even find an audience in this way, never mind positive reviews.
Arts and entertainment management, for all performing creatives, is where the rubber meets the road. Getting all the elements needed for a successful show into place at the same time may not be the most artistic accomplishment, but nothing else is likely to happen without it.
You will therefore study not only liberal arts but also accounting, marketing, finance, fundraising, venue management, entertainment law, and much besides. This allows you to have a fulfilling career in the performing arts without specializing in a particular kind of performance. Instead, you will be one of the people keeping things running from behind the scenes.
