I know this is late for you, but you still have time to decide. You can teach privately, play for a church (study organ in college as well,if you want to do that) play for weddings and funerals, accompany singers and other musicians, including during allstate competitions, accompany at a dance school,teach school-with a degree in music education, play and sing on a cruise ship, or at various restaurants, compose, get your PHD in theory and teach theory at college level or do the same with composition. Or you can study music and play because you love it and it makes you happy, and do something else for money. Take an aptitude test at college. they are free, and will give you an idea of other things you would be good at.
If you want to make your living doing music, you will probably do more than one thing.I play in a trio and a quartet, play at a restaurant, and teach, and i have accompanied a choir as well. I also have a different profession that pays better than any of those. I do music for the love of music , and my other work is something I deliberately chose for its portability, and the high demand (and decent wages).
