I have to admit I find a few of the options from the midwest…different (as we say here).
UWi - Eau Claire and St. Thomas…not really music schools.
In the WI/MN area, most kids would be looking at Lawrence, St. Olaf, Luther (Iowa) for private schools with strong music programs. UMN and Madison (WI) have fine programs too. I know that Gustavus (as well as Concordia) do music as well…that old luthern tradition runs deep here. Still St. Thomas and Eau Claire are head scratchers for me. Carthage as well - maybe it has music - but not the reputation in the area.
Good luck!
