Explanation:

The use of blank verse makes the poem sound like everyday speech. Blank verse’s regular meter gives the poem a sense of structure and stability. If the poem had a rhyme scheme, it would not sound like people were talking normally. If the poem had a rhyme scheme, the rhyme might be distracting to the reader. Rhyme schemes can sound artificial.
