Sound
The third approach Poe uses is sound. Acoustics refers to all the sound elements of a poem. Poetry is meant to be heard more than it's meant to be read, and poets have a keen ear for sounds. If you were trying to create a sad, creepy mood using only sounds, what sounds might you make? You'd probably use some low moaning sounds. In 'The Raven', Poe repeatedly rhymes words with the same low moaning sound, words like 'door' and 'floor' and 'before' and of course, 'nevermore'.
When you're reading a poem, you can infer the mood by paying attention to these three tools. Find the images in the poem, then ask yourself, 'How do these images make me feel?' Do the same with word choice. Are there any words that stand out? Consciously consider why those words might have been chosen; what emotional impact could they have?
Finally, listen to the poem. Do the sounds, the rhymes, the rhythm of the poem lift you up? Do they bring you down? Consciously find parts in the poem that elicit emotion and listen to the sound of the lines and how that moves you.
Tips for the AP Literature Test
On the AP Literature test, you'll have to analyze a poem and write an essay explaining your ideas. Certainly mood could be an important part of that analysis. Here are two tips to remember when analyzing mood.
First, while poets can create mood with images, diction, and sound, that doesn't mean that you'll find all three techniques used in every poem. It's very likely that a poet might only use one or two of those tools.
Second, poetry that's included in your exam will be complex. 'Complex' is one of those words that they use all the time on the AP test. I'm going to clue you in on a secret. If the test mentions the 'complex mood', what they're really saying is there's more than one mood. To show that you understand the complexity, and that's important to do well on the test, you should be sure to write about how the mood shifts at least once. Find the spot in the poem where your feelings shift, then break down what it is about the poem that generates that shift in mood. Not all poems have a shift in mood, so will poems on the AP exam have one? You bet. They love to choose complex poems for the exam.
Lesson Summary
Poets have three main tools to use to create mood. They have images, the elements of the poem that excite the senses. Diction refers to the words chosen and acoustics are the sounds of a poem. Imagery, diction, and sounds may not work to create mood in every poem, but there's a good chance that least one of them does.
For poems on the AP Literature exam, it's also important to look for a moment when the mood shifts. These poems are touted as being complex, which simply means that the mood can't be described in one easy statement. The mood shifts, perhaps subtly.
