Here's why:
* Harmonious intervals: Consonances are typically created by intervals (the distance between two notes) that are considered pleasing, such as perfect fifths, perfect fourths, major and minor thirds, and major and minor sixths.
* Simple ratios: These pleasing intervals are often based on simple mathematical ratios between the frequencies of the notes, which contributes to their harmonious sound.
* Stability and resolution: Consonances tend to create a sense of stability and resolution in music, often acting as points of rest or arrival.
In contrast, dissonances are combinations of tones that sound jarring or unstable. They often create tension and a sense of anticipation, driving the music forward.
