How far south is “south” to you?
U of Richmond has strong performing arts, gives music-specific merit, and has strong pre-law, including a “PPEL” major (Philosophy, Politics, Economics & Law).
Gettysburg College also has conservatory-level music but offers a BA option, has solid pre-law academics, and gives merit.
But if he likes cold, St. Olaf, Lawrence U, Rochester, CWRU, etc. might be more his speed!
College of Wooster would give him good merit, and has good music… and it gets pretty cold!
