All old Poems, Homer's and the rest, are authentically Songs. I would say, in strictness, that all right Poems are; that whatsoever is not sung is properly no Poem, but a piece of Prose cramped into jingling lines,—to the great injury of the grammar, to the great grief of the reader, for most part! What we wants to get at is the thought the man had, if he had any: why should he twist it into jingle, if he could speak it out plainly? It is only when the heart of him is rapt into true passion of melody, and the very tones of him, according to Coleridge's remark, become musical by the greatness, depth and music of his thoughts, that we can give him right to rhyme and sing; that we call him a Poet, and listen to him as the Heroic of Speakers,—whose speech is Song.
Thomas Carlyle
