Answer:
Alliteration.
Alliteration is the repetition of words or sounds through a poem to make it sound more fluent. Like rhyming words.
- "The town was really eerie, then it got really dreary, then the town is weary".
- "Mouse and mice, they like to eat cheese. Their cheese is shaped like dice, then they see some bees, now they're on the run."
Hope this helps!
