I’m the mom of a bass vocalist, and I’m a teacher, so a couple of thoughts on both of your worries.
My S, although he’d been singing with the city’s children’s choir, etc., since he was young, didn’t decide that he really wanted to pursue music as a career until just into his junior year. Then, out of nowhere, he got slammed with a crazy migraine disorder that utterly debilitated him for months. Long story short, while he managed to get enough credits to be a senior this year, he couldn’t actively do anything toward music until about a year ago. Once he could, hit got very serious very quickly and still managed to put together a decent audition rep and got ‘yesses’ from several schools. He’ll be attending UNC School of the Arts in the fall. It’s not too late.
I’ll be closing out my 24th year in the classroom in about six weeks. I entered college as a pre-law student, majoring in economics. After two years, the best thing I learned is that law was so, so not how I wanted to spend my life. I’m not a dumb girl, and no, my parents weren’t thrilled when I switched to an elementary ed major, thus putting myself on the five-year plan, but nor were they surprised.
I’ve got a pretty good gig right now: I teach reading and math to identified-gifted fourth and fifth graders. I’ve also taught sixth and eighth grade language arts and done a number of years of plain ol’ fourth and fifth grades. I. Love. My. Job. The pay sucks, (I’m in the un-unionized South.) which is really what worried my parents, Still, I get up every day knowing I’m going to get to show the kids something pretty awesome and look forward to seeing what goofy, fun, brilliant things they’ll come up with. If your heart’s telling you to teach, you’re probably going to end up in the classroom. You may as well just jump on in and save yourself the extra tuition.
Arts jobs can be hard to come by, especially down here. On my faculty, there are 35 regular ed teachers and 1 music teacher, 1 art teacher… you get the idea. A way to hedge your bets is to minor in a high-demand field, like a science. Here, at least, if you already hold a license in one subject (let’s say music), you can sit the licensure exam (I think it’s changed its name again, but it used to be PRAXIS, back in the day it was NTE.) and pick up a license in that area too.
Good luck! Life’s too short to spend 40 years doing something you don’t love.
