"How poetry is related to music through prosody, the roots of which go deeper into the human soul than any classical theory indicates"
"Why any poet who does not know exactly how many rhymes each word has is incapable of expressing any idea whatever"
"That the poetic phrase can imitate (and in this, poetry is like the art of music and the science of mathematics) a horizontal line, an ascending or descending vertical line; that it can rise straight up to heaven without losing its breath, or fall straight down to hell with the velocity of any weight; that it can follow a spiral, describe a parabola, or can zigzag, making a series of superimposed angles"
"That poetry is like the arts of painting, cooking, and cosmetics in its ability to express every sensation of sweetness or bitterness, of beatitude or horror, by coupling a certain noun with a certain adjective, in analogy or contrast"
(Charles Baudelaire, "Preface to the Flowers." Trans. J.M.)
