Read the excerpt from "annabel lee," by edgar allan poe. it was many and many a year ago, in a kingdom by the sea, that a maiden there lived whom you may know by the name of annabel lee; and this maiden she lived with no other thought than to love and be loved by me. how does the rhythm of the excerpt support the theme of the poem?

The rhythm of the excerpt supports the theme of the poem, because the rhythm is consistent, and Poe celebrates the simplicity of young love. 

And here is why I think so...

At this point in the poem, we still don't see anything bad that is about to happen. He is just talking about a young woman whose only care in the world is to love the narrator, and be loved by him. Later on in the poem we will see why that is impossible, but here, there is still no word about that.

I hoped this helped! :)
