Consonance: the close repetition of identical consonant sounds before and after differing vowel sounds. Examples of Consonance: Pitter Patter, Pitter Patter-repetition of the “t,” and “r” sounds.
Consonance is similar to alliteration in that it uses the repetition of consonant sounds. In fact, alliteration is a form of consonance that occurs at the beginning of a word. Other examples may find the repeated consonant sound in the middle or end of the word.
Assonance refers to the repetition of vowel sounds, not consonants.
