Here's how it works in the poem:
* Line 1: "Out of the night that covers me" (A)
* Line 2: "Black as the pit from pole to pole" (B)
* Line 3: "I thank whatever gods may be" (A)
* Line 4: "For my unconquerable soul." (B)
This pattern continues throughout the poem.
It's important to note that while the poem uses a ballad stanza, it's not a traditional ballad. The ballad form typically tells a story, while Robinson's poem is more introspective and philosophical.
