Consonance and dissonance are perceived qualities of musical chords and intervals, distances in pitch between two tones. Consonance is often described as relative “stability” and dissonance as “instability.” Despite the fact that words like “unpleasant” and “grating” are often used to explain the sound of dissonance, all music with a harmonic or tonal basis—even music perceived as generally harmonious—incorporates some degree of dissonance.
