This is an important thread. It would behoove all aspiring musicians to be able to read a list of where musicians in top tier and mid-tier orchestras went to undergrad and masters, and when they got their job. It may be that it differs greatly depending upon the instrument. While it may not make a great deal of difference on trombone, for example, it does make a great deal of difference on my daughter's instrument. Students not only get to put their prestige conservatory on their resume, but they are trained to sound a particular way which is immediately detected by the audition committee, blind audition or not.
I recall that several decades ago while I was attending my Big State University, the other flute players seemed to be totally unaware that their flute studies there would not lead them into a big orchestra job. While I was just taking lessons and playing in the wind ensemble while working on my academic degree in another field, these other students were performance majors and no one had ever told them the facts.
While some students would be happy to become music educators or work in a music-related field, others would not. They would choose a different emphasis or another field entirely.
As CLRN8mom said, even going to Prestige University #1 will not guarentee you that job. But it will allow you to compete. And you should always have a backup. I too believe there is money to be made in music.
