Pros
Very friendly and supportive administration and colleagues, though I think this would depend on your department. Classes within the School of Music were wonderful to teach because the students are so great. The School of Music in general is a great place to be employed because of the tight-knit nature of the group.
Cons
Mostly the students, they can be a handful depending on what course you are teaching. If you ever teach classes for non-majors(regardless of field), be prepared to grow thick skin. They must have put something the water - entitlement up the wazoo. As an adjunct music faculty member it can be hard to keep a consistent course load, especially if you're new. Unless you have a tenured position-which, let's be honest, are hard to come by these days-the number of classes you teach can fluctuate semester to semester, and therefore your salary does, as well.
