Also want to say that UNT, where @Shellg’s son is going, is a renowned and amazing jazz program. Your kid should absolutely put it on his list.
Starting early like you are, your kid will be in a situation a lot more like her son’s and less like mine. Your kid will be able to take summer programs and get to know profs and schools. So, my idea of casting a wider net may not apply the same to you, once you have done so many years of preparation.
