If Christopher lives otherwise than in a tree, and is maintained otherwise than by gathering roots and berries, he might notice that the principles of physics/engineering finds application in the construction of many more objects than stadiums---they underly the construction of everything he lives in and uses. Moreover, if a therapeutic effect of Mozart on cows is the BEST example he can come up with on his side, then his argument is lost at the outset to the point of comedy. I think we will find ourselves on firmer ground if we take music as A BRANCH of mathematics: abstracted from the symbolic system of quantity relationships which, we find, has deep roots in the real world. This doesn't mean that one uses music to build bridges, any more than one employs topology theory in prescribing medication. Only that the relationships underpinning the activities in question share certain logic connections. By the same argument, baseball and billiards are branches of mathematics as well, and I will stand by that. Maybe literature is too, although it is harder to trace the connections.
