Answer:
Modern classical music tended to be dissonant rather than tonal because composers used chromatic scales
Explanation:
Dissonant chords: Chords that sound as if the notes do not belong to the same scale, as if there has been a tune, so to speak.
The construction and alleviation of a tension in music (dissonance and resolution) can occur on all levels from subtle to denser, and on a large scale is primarily responsible for what many call the beauty, emotion and expression of music.
