"For my own part, I find considerable meaning in the old vulgar distinction of Poetry being metrical, having music in it, being a Song. Truly, if pressed to give a definition, one might say this as soon as anything else: If your delineation be authentically musical, musical not in word only, but in heart and substance, in all the thoughts and utterances of it, in the whole conception of it, then it will be poetical; if not, not. Musical: how much lies in that! A musical thought is one spoken by a mind that has penetrated into the inmost heart of the thing; detected the inmost mystery of it, namely the melody that lies hidden in it; the inward harmony of coherence which is its soul, whereby it exists, and has a right to be, here in this world. All inmost things, we may say, are melodious; naturally utter themselves in Song. The meaning of Song goes deep. Who is there that, in logical words, can express the effect music has upon us? A kind of inarticulate unfathomable speech, which leads us to the edge of the Infinite, and lets us for moments gaze into that! "Nay all speech, even the commonest speech, has something of song in it: not a parish in the world but has its parish-accent;--the rhythm or tune to which the people there sing what they have to say! Accent is a kind of chanting; all men have accent of their own,--though they only notice that of others. Observe, too, how all passionate language does of itself become musical,--with a finer music than the mere accent; the speech of a man even in zealous anger becomes a chant, a song. All deep things are Song. It seems somehow the very central essence of us, Song; as if all the rest were but wrappages and hulls. The primal element of us; of us, and of all things. The Greeks fabled of Sphere-Harmonies: it was the feeling they had of the inner structure of Nature; that the soul of all her voices and utterances was perfect music. Poetry, therefore, we will call musical Thought. The Poet is he who thinks in that manner. At bottom, it turns still on power of intellect; it is a man's sincerity and depth of vision that makes him a Poet. See deep enough, and you see musically; the heart of Nature being everywhere music, if you can only reach it."
