Atsushi TADOKORO-Consonance and Dissonance

A chord is created by three or more notes of different frequencies emitted simultaneously. The resulting sound depends on the pitch ratio of the notes. An overlap of notes close to a simple integer ratio is considered "consonance," and that of a more complex ratio is considered "dissonance.” In Western music, consonance and dissonance correspond to relaxation and tension. When tension is released, a coherent musical structure is created (cadence). Society is also like a chord, with ideas and thoughts of various scales coexisting. Sometimes they harmonize, and sometimes they collide, resulting in a state of dissonance. Dissonance leads to an uneasy psychology and drives consensual resolution. On the one hand, a constant state of harmony is dull and mundane. On the other hand, excessive dissonance leads to tension and anxiety. In this balance between harmony and disharmony, a swell of emotions and stories is perceived, and emotion is born. The concept of harmony expands and encompasses the state of dissonance, dismantling it. In this work, an attempt is made to express tension and relaxation through sounds and images and to reflect on the current social situation.
