Consonance – Definition
Consonance is the quality of two or more notes sounding stable, harmonious, and relatively free of tension. In Western music, consonance is commonly contrasted with dissonance.
What is Consonance?
Consonance is most closely associated with intervals that have simple frequency relationships, such as the octave and the perfect fifth. These intervals have traditionally been perceived as stable and pleasing to the ear.
The perception of consonance has evolved over time and can vary between musical styles and cultures. Intervals and chords considered consonant in one context may be treated differently in another.
How is Consonance used in piano playing?
Pianists use consonance to create moments of stability and resolution within melodies and chord progressions. Consonant intervals and chords often mark the ends of musical phrases or provide a sense of arrival after passages of greater harmonic tension.
Balancing consonance and dissonance is an important aspect of harmony, composition, improvisation, and musical expression on the piano.
