Usage

What does dissonance mean? Dissonance is harsh, inharmonious noise—cacophony. It can also refer to stark disagreement or lack of consistency. In both cases, a close synonym is discord. In the context of music, the word dissonance is used in a specific way to refer to a combination of sounds thought to be inharmonious (often ones intentionally composed to be so). It can also refer to a chord or interval that features such disharmony. In music and in general, dissonance is the opposite of consonance, which means harmony, agreement, or accord. In psychology, the term cognitive dissonance refers to the unease a person feels when they have two or more contradictory or incompatible beliefs. An adjective form of dissonance is dissonant. Example: Leaders in both factions of the party promised harmony, but so far there has been nothing but dissonance and constant arguing.

Explanation

Disagreeable sounds can be called dissonance. You know it's dissonance if you have the strong desire to cover your ears with your hands. Racket, noise, dissonance — all can describe sounds that are not pleasant. While some musicians purposely add a little dissonance into their melodies to create an unexpected sound, others, like someone who just started drum lessons, creates dissonance by accident. Dissonance can also be a conflict between people or opinions, like the dissonance you feel when you want to do something but your parents say "no."
