What is dissonance?

What is dissonance?

• A. The quality of a pitch, interval, or chord, that makes it seem unstable or tense.
• B. The quality of rest or resolution.
• C. A soft, gentle sound.
• D. A loud dynamic marking.

Answer: (A)

Dissonance is the quality of sounds—pitches, intervals, or chords—that feels unstable or tense, creating a sense of tension that wants to move toward something more settled. This instability comes from how the frequencies interact: some intervals sound rough or “clashy,” like a minor second or a tritone, which our ears interpret as needing resolution. In most music, dissonances are used intentionally against a stable, consonant harmony and then resolve to that stability, driving musical motion. The other descriptions—rest or resolution, a soft sound, or a loud dynamic—refer to different musical ideas (consonance/resolution, timbre, and dynamics, respectively) and do not define dissonance itself.
