Look closely at the first stanza of “The Raven.” What is its rhyme scheme? Provide a short explanation for your answer. Once upon a midnight dreary, while I pondered weak and weary,
Over many a quaint and curious volume of forgotten lore,
While I nodded, nearly napping, suddenly there came a tapping,
As of some one gently rapping, rapping at my chamber door.
“'Tis some visitor, “I muttered, tapping at my chamber door —
Only this, and nothing more.”
