Music where all 12 tones of the chromatic scale are of equal importance is called: A. polytonal B. noise C. atonal D. democratic music

The correct answer is C. atonal.Atonal music is a type of music where all 12 tones of the chromatic scale are of equal importance, and there is no tonal center or key. In atonal music, the pitches are not organized around a specific key or tonality, and the melodies and harmonies do not follow traditional tonal patterns. This approach to music composition was developed in the early 20th century and is associated with composers such as Arnold Schoenberg, Anton Webern, and Alban Berg, who were part of the Second Viennese School.
