This is a great question, I have a great friend that went into the music field and the course of action he took has work for him. He received a degree from Columbia College in Chicago, IL. The program encompassed a lot of the business behind the music (business management, production, business models, ETC), he specialized in audio engineering which gets you in the door with production companies, how to create, edit and produce music. this helped him to launch his career and work with marketers to get his name out and he has been quite successful. I hope this helps!!! Start small and understand what you really want to accomplish, research schools like Columbia College, look for interns and production companies to gain exposure and see if it is really a fit for you.
