Read the excerpt from “in the greenest of our valleys,” by edgar allan poe. vast forms that move fantasticallyto a discordant melody; while, like a rapid ghastly river, through the pale door, a hideous throng rush out foreverhow does poe use a sound device in the excerpt? he uses euphony to illustrate the constancy of nature. he uses alliteration to draw attention to the suffering. he uses cacophony to emphasize the evil nature of tragedy. he uses internal rhyme to enhance the rhythm of his lyrical poem.
