so very random…
I went to an ivy and despite not having performance majors I had someone who attended at same time that ended up being a professional, fairly high-level level, opera singer and another ended up a fairly high-level conductor. Neither thought that was their path. They ended up with lots of 1:1 coaching with professors and lots of coaching on grad school. I had a friend, not even a music major, who was a high level musician. They had a piece of music commissioned for their senior year for orchestra by the school, and their teacher came up weekly from another university to teach them (the university didn’t have someone on staff good enough for their instrument). Resources at these places are remarkable. (My friend considered conservatories, but knew that wasn’t their path, but wanted to keep playing “for fun” in college). Also have a friend who is a professional string player now.
Obviously, if you KNOW your path, it likely makes no sense to go to school w/o your major, but it is shocking how many ways to end up in a career there are.
