Tone調不合的意思

"Tone調不合" is a term used in music to describe when two or more notes played simultaneously create a dissonant or unpleasant sound. In Western music theory, this usually refers to intervals that are not part of the diatonic scale or that do not conform to the rules of harmony.

Dissonance is a musical term that describes the tension or clash produced when two or more notes sound together or consecutively. It can create a sense of unrest or instability, which can be resolved by moving to a more consonant interval or chord.

Consonance, on the other hand, refers to intervals that sound pleasant or stable when played together. These are typically the intervals found within the major and minor scales, such as perfect fifths, octaves, and major and minor thirds.

In music composition and performance, the concept of consonance and dissonance is used to create musical interest and to guide the listener's ear through a piece of music. By using dissonance and then resolving it, composers can create tension and release, which is a fundamental element of musical structure.
