Well, that is because it can yield a guarantee of admissions, but nothing prevents her from showing up on campus and choosing music instead.
This is fine, but if it’s a real possibility, make sure she is not following athletic money. I know kids that wonted out of their sport for one reason or another but were beholden to the scholarship. I know someone (older than me) how has a complicated relationship with their sport. They were on the national team but ultimately were resentful of all they had to give up in college to do that, but were in no financial position to walk away from the scholarship.
