Allegheny offers up to 2k and University of Puget Sound offers up to 8K. The scholarship requirements will vary by school. Some schools require one ensemble some schools may require two, some may require a music class as an elective but they also may offer free private lessons as part of the package. For a student who loves their instrument or loves to sing that alone can be worth it.
I know in our case my student plans on playing in college regardless, if he is able to and we deliberately looked for schools that offered these extra opportunities for him to earn a little extra money doing something he would do anyways.
I am not sure if Lawrence was already mentioned but they offer it as well. I just don’t have the details.
Bottom line is it is definitely out there but I would not expect awards to be at the level of a tuition waiver. Still worth pursuing though.
