Not music but D18 is doing a dual ballet BFA and BSc Hons at Utah (note they also have a BMus course, see https://advising.utah.edu/majors/quick-look/music-bmus.php ). The BFA is somewhat similar to the BMus, requiring about 90 semester credits for the major.
She is managing to fit in a second major with about 50-60 credit hours (Env Studies in her case but math would have worked too, though no chance of doing the 80+ credits and labs needed for an engineering major). She’ll end up with about 160 semester credits (compared to the standard 120) taking account of the extra required honors courses, in 4 years (plus a half course load the first summer). That means 20-22 credits most semesters which is busy but quite doable (she has a 3.9 GPA and 89 credits after two years, excluding APs), at least for a strong student (4.0UW/35 ACT/8 5s in APs in HS).
Utah seems to make this easier than any other college I’m aware of, since they have plenty of online courses which allow timing conflicts to be mitigated and offer a fairly comprehensive set of lower level courses in the summer, equivalent to a full semester, because so many OOS students stay to gain residency the first summer. Merit aid is good too, though it’s academic based, we didn’t see anything based on talent. Hope that helps.
