Friday. Only on rare occasions am I reminded that man too has a voice, as well as birds and quadrupeds, which breaks up the stillness of nature with its peculiar accent. The least sound pervades and subdues all space to it as long as it fills my ear. Contrasted single with the silence, it is as wide as it. Music is the crystallization of sound. There is something in the effect of a harmonious voice upon the disposition of its neighborhood analogous to the law of crystals; it centralizes itself and sounds like the published law of things. If the law of the universe were to be audibly promulgated, no mortal lawgiver would suspect it, for it would be a finer melody than his ears ever attended to. It would be sphere music.
