I do think she needs to find volunteer groups, if only to make the next 10 weeks better, as those won’t be competitive. Not being able to play in the orchestra would be tough for a music kid, is there another orchestra, band, or ensemble?
Sending a transfer application could be an outlet, a reassurance she doesn’t need to stay if she can’t stand it. Applying doesn’t mean she must transfer. However deadlines are going to come up soon.
Based on your description - academic-y, music, neuroscience, I’m going to recommend she look seriously into St Olaf. It’s outside of her preferred region (in a college town 45mn south of the Twin Cities) but it has everything she seems to want - even th wholesome/don’t drink part (it’s a dry campus). Their transfer admission deadline is Nov1.
Wrt music, 1/3 students are serious musicians and there are dozens of music ensembles; transfers can submit a music scholarship sample - music scholarship students don’t need to major in music but must join an ensemble - and for that she’d need to contact the transfer adviser as well as the music adviser detailing her ability&experience.
