Are there rhymes?
"Because I could not stop for Death—" by Emily Dickinson is organized into six four-line stanzas and has the metrical pattern of common meter, alternating lines of iambic tetrameter and iambic trimeter. This gives the reader an expectation of an abab rhyme scheme, but the expectation is not actually fulfilled. Many of the lines are completely unrhymed, while others use assonance or slant-rhyme in place of full rhymes.
In the first stanza, the second and the fourth line rhyme "immortality" with "me", although this is more properly a case of assonance as the consonants preceding the vowels differ. In the fifth stanza, we see an "identical" rhyme of "ground" with "ground". There is also an "internal rhyme" linking the ends of the phrases "We slowly drove" and "where Children strove". The poem also makes extensive use of internal assonance and alliteration, but those are not actually rhymes.
