What Can We Infer Has Happened?

This poem by Edgar Allan Poe is best known for the diacopic (repetition of a word or phrase with one or two intervening words.)use of the word "bells." The poem has four parts to it; each part becomes darker and darker as the poem progresses from "the jingling and the tinkling" of the bells in part 1 to the "moaning and the groaning" of the bells in part 4. This poem can be interpreted in many different ways, the most basic of which is simply a reflection of the sounds that bells can make, and the emotions evoked from that sound.
