What is "dissonance" in music?

Dissonance in music refers to a combination of notes that create a sense of tension or instability. This tension arises because dissonant intervals do not blend smoothly or harmoniously, making the listener feel a moment of unease or anticipation. In the context of music theory, dissonance is essential for creating contrast and emotional depth in a composition. Composers often use dissonant chords to build tension, which can then be resolved into consonant chords, providing a satisfying sense of release.

Understanding dissonance is crucial for singers and musicians, as it plays a significant role in the dynamics of musical expression and the overall structure of pieces. Its use can evoke a wide range of emotions and add complexity to musical narratives.
