Serial music originated from the twelve-tone technique because it provided a new way for composers to organize and structure their music. The twelve-tone technique, developed by Arnold Schoenberg, sought to move away from traditional tonal harmony and instead use all twelve pitches of the chromatic scale in an ordered and systematic way. This approach allowed for a more equal distribution of musical material and a departure from the hierarchical relationships found in tonal music. As a result, serial music emerged as a way for composers to explore new avenues of expression and composition. **
