Adrienne Rich wrote:
In a political culture of managed spectacles and passive spectators, poetry appears as a rift, a peculiar lapse, in the prevailing mode. The reading of a poem, a poetry reading, is not a spectacle, nor can it be passively received. It’s an exchange of electrical currents through language—that daily, mundane, abused, and ill-prized medium, that instrument of deception and revelation, that material thing, that knife, rag, boat, spoon/reed become pipe/tree trunk become drum/mud become clay flute/conch shell become summons to freedom/old trousers and petticoats become iconography in appliqué/rubber bands stretched around a box become lyre. Diane Glancy: Poetry uses the hub of a torque converter for a jello mold. I once saw, in a Chautauqua vaudeville, a man who made recognizably tonal music by manipulating a variety of sizes of wooden spoons with his astonishing fingers. Take that old, material utensil, language, found all about you, blank with familiarity, smeared with daily use, and make it into something that means more than it says. What poetry is made of is so old, so familiar, that it’s easy to forget that it’s not just the words, but polyrhythmic sounds, speech in its first endeavors (every poem breaks a silence that had to be overcome), prismatic meanings lit by each others’ light, stained by each others’ shadows. In the wash of poetry the old, beaten, worn stones of language take on colors that disappear when you sieve them up out of the streambed and try to sort them out.
