What Music where all twelve tones of the chromatic scale are of equal importance is called?

Music in which all twelve tones of the chromatic scale are of equal importance is called "twelve-tone music" or "dodecaphony." This compositional technique, developed by Arnold Schoenberg in the early 20th century, ensures that no single note dominates, creating a more democratic use of pitches. It often involves a specific sequence or series of the twelve tones that serves as the foundation for the composition.
