Hi Michael, This is a loaded question and, since I don't know where you are in your studies, I will recommend this site for information. If you don't see something that interests you please reply to my answer. The site is: Careers in Music Business - https://www.careersinmusic.com/music-business-careers/
Hi! Teaching, music therapy, business manager, agent, producer, recording engineer, entertainment lawyer, publishing, A&R...these are just a few. Do you want to make music or help others make music? Are you a performer or behind the scenes person? Knowing the answer to these questions will help you discover which area of music to pursue. Sometimes, you have to try them out to figure out which one you really like. Sometimes, we think we want a certain career, but then when we actually work it, we may discover that we really want to pursue another area.
All the best!

You could learn how to produce, song write, become a critic and review artists, songs, albums, and concerts.
Myself personally, took a different career path other than music but since I’ve been playing music since I was 10, I had to find some sort of musical outlet after I graduated high school (and get paid for it). So after high school I auditioned for the Reserve Army Band and got accepted. The commitment is one weekend a month and two weeks in the summer. I got to travel and play music around the U.S. and also got paid for every weekend, gig, and training event. Not to mention the school tuition benefits, medical benefits, VA loan (for your house), and much much more! Hopefully this helps at least give you another option you did’t know about. Best of luck!
