What’s his UW GPA on a 4.0 scale (with A- as 4.0)? Utah offers their OOS Presidential scholarship for 4.0/36 (full tuition plus $5000 towards room and board): https://financialaid.utah.edu/types-of-aid/scholarships/freshman/presidents-scholarship.php#nonrespres
They also have competitive full rides (25 per year) and I suspect would love to give one to a music performance major as they seek to include a variety of different majors in the cohort: https://honors.utah.edu/eccles-scholarship/
It is very possible to do a performance degree in combination with a second major (D is doing a combined BFA and BSc with Honors and will finish in four years).
