Congrats to your kid on their accomplishments!
Agreed that there’s no particular major necessary for pre-law. Understood that they want a strong academic foundation, but that can be achieved with a music major, or a music major plus a minor. A double-major is possible but not necessary, and said major need not be anything politics/policy oriented unless that’s a specific desire.
Reach schools that are extremely strong for music as well as other academics, and which include sports culture and Greek life, include Vanderbilt, Northwestern, and USC(California). U of Richmond would also be worth a look (the PPEL major may be of interest). In terms of public flagships, UMichigan, tOSU (has a PPE major, and the conservatory is double-major-friendly), Indiana U… I’m sure there are more that I’m forgetting.
In a less sporty/Greek vein but still potentially worth considering, are Hopkins, URochester… and the LAC’s with conservatories (Oberlin, Lawrence, Bard… and St. Olaf which doesn’t have a separate conservatory but still has extremely strong music performance + academics). But it sounds like these may not have the vibe your child is looking for. Sewanee might be worth a look, as a more Greek-oriented LAC with strong music… but not if D1 sports culture is a must-have.
Budget-wise, if you run the Net Price Calculators for expensive private U’s like Vanderbilt/Northwestern/USC/Richmond, can your family afford the projected cost of attendance?
