I went to fairly small private college for Music, and all my music professors were really great, every one. Even the couple that were considered the worst were decent teachers, it’s just that some were amazing, and made everyone else look mediocre.

Once you got out of the Conservatory, and started experiencing other subjects, the quality was variable. I had some excellent profs, but also some fairly bad ones. The worst were the adjunct teachers who were only doing it for a side hustle, they generally weren’t too invested.
