This aspect of nonordinariness is one of virtues of the arts, that of expanding the repertoire of processes of mind that we call thought. This expanding and expanded state is a source of pleasure, another virtue. The crass and immediate manipulation of feelings in the name of art, without the interventions of attention and thought is precisely nonart. The subject, however, is musical art, because that's the one I know best. First, I'd like to say a few words about what distinguishes music from the other arts.
Music is the most abstract art.
Most conductors can look at a score and produce in their minds an ideal performance with all these attributes, not having to bother about practical matters like the essentially unstable design of the French Horn. Music is almost by its very abstract nature synaesthetic. I remember my first year at college and going to recitals and concerts. To my joyful amazement, at every one I found the first row filled with the mathematics faculty, and the second filled with the physics faculty. I felt a certain rightness about this and since then I've observed that mathematicians and physicists, particularly those of the theoretical type had an inordinate love, appreciation and knowledge of music.
