What were the characteristics of Serialism music?

Serialism is a compositional technique that emerged in the 20th century, characterized by the systematic ordering of musical elements such as pitch, rhythm, dynamics, and timbre. It often involves the use of a twelve-tone series, where all twelve notes of the chromatic scale are arranged in a specific sequence, which serves as the basis for the composition. This method emphasizes structure and complexity, moving away from traditional harmonic and melodic frameworks. Composers like Arnold Schoenberg and Anton Webern were pivotal in developing and popularizing serialism, leading to a distinctive and avant-garde sound.
