Sphere Music - Some sounds seem to reverberate along the plain, and then settle to earth again like dust; such are Noise, Discord, Jargon. But such only as spring heavenward, and I may catch from steeples and hilltops in their upward course, which are the more refined parts of the former, are the true sphere music - pure, unmixed music - in which no wail mingles.
