Cognitive Dissonance Definition. Cognitive dissonance occurs when tension arises between a person's attitudes or beliefs and a decision that contradicts those pre-existing modes of thinking.

For other uses, see Literary consonance, North/South Consonance Ensemble, and Dissonance (disambiguation). In music, consonance and dissonance form a structural dichotomy in which the terms define each other by mutual exclusion: a consonance is what is not dissonant, and reciprocally. However, a finer consideration shows that the distinction forms a gradation, from the most consonant to the most dissonant. Consonance and dissonance define a level of sweetness / harshness, pleasantness / unpleasantness, acceptability / unacceptability, of the sounds or intervals under consideration.
