Consonance

Consonance is a literary device, often used in poetry. It is the repetition of consonant sounds in a short sequence of words, for example, "her brown curly hair." Alliteration differs from consonance in that in alliteration, the repeated consonant sound must be at the beginning of each word. In half rhyme, the terminal consonant sound is repeated.

In music, a consonance is a harmony which sounds pleasant and stable, as opposed to a dissonance.
