What is a shifting meter?
Most poems include a shift, also called a turn, or the Italian word “volta,” which expresses a change in the poem. This shift could be as simple as a summary of the preceding lines, or it could be a dramatic transformation of the speaker's point of view. One way of identifying a rhetorical shift in a novel or poem is to look at the use of conjunction words, like but and therefore. This is usually an indication that there is some sort of shift in thought.
