Dissonant harmonies tend to resolve to consonant harmonies ? ?

True.

Explanation:

The consonant harmonies cause the sensation of harmony, pleasant sound. Meanwhile, the jarring harmonies cause a sense of tension. This feeling can even be felt by people who do not understand music. Since they know a consonant harmony as a "happy" chord. Already a jarring harmony is felt as a lower chord. When together, dissonant harmonies tend to resolve consonant harmonies.

Finally, we can define consonant harmonies and dissonant harmonies like this:

Consonant harmonies: chords that sound harmoniously;

Dissonant harmonies: Chords that sound as if the notes do not belong to the same scale, as if there has been a tune, so to speak.
