Since he’s a freshman remind him that he has to earn academic acceptance to college as well and to keep his grades up. 
Our experience with UNT was large academic scholarship, small music scholarship. I don’t know what the maximum music scholarship would be, but currently any scholarship $1000 or more also gives the student an out of state tuition waiver, which is worth more than both my son’s merit scholarships combined.
I don’t think you necessarily have to have a huge list of schools but you do have to have a smart list, and when cost is a consideration and auditions are required. My son applied to four schools.
