Here's why:
* Dissonance is a musical interval that sounds unstable or tense.
* Consonance is a musical interval that sounds stable or harmonious.
The movement from dissonance to consonance creates a sense of completion and satisfaction, as the tension is resolved. This is why it's often referred to as a resolution.
Other related terms:
* Cadence: A musical phrase that ends with a resolution, typically ending on a consonant chord.
* Harmonic progression: The sequence of chords in a piece of music, often featuring dissonances that resolve to consonances.
