Weegy: Three composers who experimented with the twelve-tone system are Arnold Schoenberg, Anton Webern, and Alban Berg.
The twelve-tone system was developed by Arnold Schoenberg in the early 20th century as a new method of composing music. It is based on the use of all 12 notes of the chromatic scale, arranged in a particular order called a tone row, which serves as the basis for a composition. Schoenberg's pupils Anton Webern and Alban Berg also developed this system, they wrote music that was considered more complex and dissonant than traditional tonal music.
