I would define, in brief, the Poetry of words as the Rhythmical Creation of Beauty. Its sole arbiter is taste. With the intellect or with the conscience, it has only collateral relations. Unless incidentally, it has no concern whatever either with duty or with truth.
Taste is the intermediate faculty which connects the active with the passive powers of our nature, the intellect with the senses; and its appointed function is to elevate the images of the latter, while it realizes the ideas of the former.
I regard texture similar to the function of taste buds in our mouths. But in a visual form. Texture does create a specific flavour which affects our senses.
