The number of majors doesn’t always say much about the quality of a music department. Harvard doesn’t have many majors, for instance, but the dept. is excellent and so are the extracurriculars. I know a student there currently who was a prodigy as a kid and she does all kinds of things musically there, both in classes and outside. Of course, computer science anywhere involves many math courses and the fact that math and CS are in the same dept. may not mean much either. My son was a CS major at an Ivy and had a lot of math and science classes. I’ll look at the site (and ask him) how many courses were actually CS. I don’t have a particular connection to Davidson and others may know more, just suggesting maybe look deeper if it appeals for other reasons.
