Alliteration

Definition: Alliteration means the repetition of the first syllable in the word and/or phrases

Example: Macho Pursuits

Sliding, slipping, gliding, tripping
If ice skating's too exhilarating
Try cake icing, it's quite exciting
Slapping, slopping, frosted topping.

Significant: I think that that alliteration is not necessary to appear in poem like assonance because it’s also make the poem sound more interesting and funnier. And also when you say word that have same vowel of syllables too fast, then your tongue might twist.
