Agree with Ithaca as a good match, and I too would consider Lawrence to be a high match.
Also, have her take a look at St. Olaf College one of the strongest music programs among liberal arts colleges, with excellent academics in other subjects as well. Location is in a cute college town, 45 minutes south of Minneapolis, with regular bus service to the Minn. airport and other stops in the Twin Cities. It is primarily liberal-leaning and informed by its Lutheran values— students of all faiths and no faith attend. Your D is right at their average GPA, and not too far below their average SAT. Her extensive music background would likely be a plus in admissions, as would her being full-pay, so I would consider St Olaf as a potential high match/low reach for her. The school offers some great music scholarships as well (via audition), and the ED acceptance rate is quite high, I believe.
