Browning used a somewhat unusual stanza structure and rhyme scheme in this poem. The poem is constructed of quintains—five-line stanzas—each with an ABABB rhyme pattern. The result is musical but strange to the ear, with the final line in each stanza subverting the natural ABAB form. Perhaps Browning chose this unsettling form to better express the poem’s eerie tone.
