Dissonance

Dissonance has several meanings, all related to conflict or incongruity.

In music, dissonance is a property of an interval or chord. See consonance and dissonance.

In poetry, dissonances is the deliberate avoidance of patterns of repeated vowel sounds (see assonance). In general, words that are difficult to pronounce or contain harsh, rasping consonants are considered dissonant. Dissonance in poetry is similar to cacophony and the opposite of euphony.

Cognitive dissonance is a state of mental conflict.
