I would say that if you are truly passionate about music, you should at least give it a try. Get a Bachelor's in music. During those four years you will experience many things that will help you determine if you should truly go for it. Nobody works without a master's these days anyway. So, if those four years change your mind, you can still choose a different path, like getting an MBA, going to Law School, or anything else you would like. Life is too short to live with regrets.
