What is dissonance?

What Does dissonance Mean

A dissonance is a sound that is unpleasant . The term has its etymological origin in the Latin word dissonantia .

Dissonances put a strain on the ear . That is why these sounds generate a rejection , unlike what happens with consonances . This is because the consonance is not tight and therefore pleasant.
It can be said that a dissonance is a musical interval that, due to its characteristics, is unpleasant to the ear. It should be noted that the intervals are established from the difference in pitch between two notes. Dissonant intervals, in this framework, do not respect the rules of harmony and are more tense than consonant intervals.

The idea of dissonance is also used with reference to the absence of proportion, conformity or balance that something should have . In this way, dissonance is associated with strangeness .
A cognitive dissonance , for example, occurs when an individual develops two thoughts or behaviors that are in conflict with each other or with their beliefs. There is, in these cases, an incompatibility between these two simultaneous cognitions.
Before the irruption of a cognitive dissonance, the subject tends to produce new beliefs that allow him to eliminate tension and achieve harmony based on internal coherence.
Let us suppose that a young man, in his upbringing, was instilled in the importance of dialogue and avoiding all kinds of violence . However, one afternoon he sees a man hit a child and is forced to intervene, using force first to make the assailant stop and then to subdue him. The attacker, due to a blow from the young man, ends up hospitalized in serious condition. The boy, faced with this situation, experiences a cognitive dissonance caused by the clash between his moral rejection of violence and his own violent actions, which he finally resolves with the introduction of other values ​​that allow him to justify himself (such as the obligation to assist a person who is defenseless).
The concept of cognitive dissonance appeared in 1957 when it was proposed by Leon Festinger , an American psychologist, in his book entitled Theory of Cognitive Dissonance . Throughout its pages, the work explains that when an individual encounters this incongruity, an inevitable process of production of new beliefs and ideas begins with the aim of reducing tension until consonance and coherence are restored .

When making decisions, the effect of this type of dissonance is of considerable importance. Every time we make an effort, it is expected that the cost involved will be rewarded with a reward that we can appreciate. This reward is nothing but success, which we pursue in exchange for our dedication. If what we get is the opposite, that is, failure , then a dissonance occurs.
When faced with failure, we can try to reduce dissonance in a number of ways, one of which is to focus on a future reward ; An example is given when we say to ourselves "you can learn everything from everything, I will never make mistakes this way again . " We can also detect certain benefits that we previously ignored so that the impact is not so great: for example, after a disappointing purchase because the product is not as we expected, we have the option of being satisfied with certain benefits that we had not anticipated.
Philosophy does not see this kind of dissonance as an inherent phenomenon of our species but as a way of thinking and acting that is related to religion and that is put into practice to get ahead after a very painful experience or that causes deep discomfort. .
