Which term describes a sound that is considered harsh or uncomfortable in music?

Dissonance is the term used to describe a combination of sounds that creates a sense of tension or unease in music. In contrast to consonance, which provides a feeling of resolution and stability, dissonance is characterized by intervals or chords that clash or do not blend smoothly. This harsh or uncomfortable quality is often used intentionally by composers and musicians to evoke emotions, create drama, or build tension within a piece of music.

In the context of music theory, understanding dissonance is crucial because it allows musicians to explore the dynamics of musical expression. The use of dissonance alongside consonance can create a rich harmonic language that influences the overall emotional impact of a musical work.
