Nobody's mentioned yet the elephant in the room: cost.
If this student is taking on debt for music school, and hopes to be a full time professional musician, that's a very bad idea. If the schooling is free or nearly so, or being paid for by his parents AND WITHOUT RISK TO THE PARENTS' FINANCIAL STATUS, then the decision can be made purely on the subject matter and its relevance to his anticipated future career path.
Full time professional musicians who make all their living from music-related activities (as opposed to music teachers in a public school) tend to have very low earnings and highly variable earnings. Get out of school at 22, debt free, and want to be a music pro? Fine. Live off ramen noodles and peanut butter sandwiches, get six roomies, tour in a broken down van with five other guys, whatever. You're young and springy, you can live pretty much on air, don't sweat it, if it doesn't work out (and it almost always won't), you can go back to school, get a degree in something where you can earn a living, and you can dine out on your stories of "when I was a full time pro" the rest of your life.
Now consider the same situation, except when you launch at 22 you've got $100,000 (or even more!) debt hanging on you for the rest of your life. You're hosed. That millstone is going to drag you down.
