Norman Brodeur says that Music is pre-eminent among the arts for the order and clarity, the sharply defined character, of its elements. Music moves us, sometimes too overpowering emotion. It does so through well-defined structures, through an order of tones and rhythms. It is not the mere sound of drums but their rhythmic beating that stirs us. Here we come upon the central paradox of music, the paradox that defines music as a worthy object of sustained intellectual wonder: Music is the union of the rational and irrational, of order and feeling.
