I hate to twist your tail, Stoat -- pun intended -- but that doesn't necessarily wash.
Music is mathematics in sound. Some perceive that more readily than the Pythagorean Theorem, but a grounding in mathematics, particularly Euclidean Geometry, might have the same effect you desire.
But classical music more properly belongs to the Dead White Male side of things, better known as Western Culture. There are universities that still teach the Great Books, but even they turn out their share of socialist intellectuals.
Teaching math, music, Western Culture or the Great Books won't necessarily produce conservatives because of a logical and coherent foundation. When I say Marx and Keynes have a logical and coherent foundation to their philosophies, I'm not being facetious. Marxism is a religion with all the same facets as a religion, such as a logical end to history and a paradise to be worked for.
So perhaps teaching religion would help produce conservatives, but there we run into a different issue -- whose religion? And which facets of it? A course in Aquinan logic might well produce what you are looking for, but it would also miss the essence of what a religion shuuld be.
I'm flailing around here too, but I don't think classical music is a magic bullet. I'm not sure there are magic bullets any more. Perhaps a classical education based on all of the above might produce more conservaives, but I'm sure that St. John's on Long Island turns out its share of liberals anyway.
I wasn't flailing.
but I don't think classical music is a magic bullet.
I never suggested that it was.
Party Pooper! Where is the passion?
