Final answer:
The rhyme scheme in Thomas Hardy's "The Voice" has a pattern of ABAB CDCD, characterized by alternating indents and a refrain at the end of each stanza.
Step-by-step explanation:
The rhyme scheme in the excerpt from the poem "The Voice" by Thomas Hardy is a little complex and does not conform to the simpler patterns like AABB or ABAB. Instead, the excerpt shows a pattern of ABAB CDCD. The indented lines hint at the lines that rhyme with each other, with the indentations normally alternating, except for a couplet in the middle of the stanza. Furthermore, Hardy utilizes a refrain at the end of each stanza which contributes to the overarching mood of the poem.
