What musical term refers to the effect of tension caused by using discords?

The term that refers to the effect of tension caused by using discords is dissonance. In music, dissonance occurs when two or more notes clash or are played together in a way that creates a sense of instability or tension. This tension is often resolved through consonance, where the notes blend harmoniously, providing a feeling of rest or completion. Dissonance serves a vital role in music; it creates emotional depth and drives musical narratives forward by generating anticipation for resolution.

In contrast, harmony refers to the way in which different notes sound together, typically in a consonant manner, while consonance is specifically the combination of notes that are stable and pleasing. Resolution describes the process of moving from dissonance to consonance, often resulting in a feeling of satisfaction after tension has been created. Understanding these terms and their relationships is essential for analyzing and appreciating music effectively.
