Answer:
It is using the slant rhyming scheme.
Explanation:
These lines from the poem "The Municipal Gallery Revisited" by William Butler Yeats is using the slant rhyming scheme. Slant rhyming is when the words may sound similar but not identical. Most of these slant rhymes are formed by words that have similar consonants but different vowels or vice versa.
It's not a strict rhyme as the rhymes changes throughout the poem.
It is not 'internal rhyme' either as there are no words that rhyme with any line.
And lastly, it is not double rhyme as there are no two-syllabic words but instead only monosyllables.
