Austrian composer Arnold Schoenberg in a suit, seated at a piano and holding a conductor's baton, appears to be conducting music in a wood-paneled room. — Arnold Schoenberg Austrian-American composer Arnold Schoenberg was one of the most influential teachers of music composition of the 20th century. He also was known for his creation of new methods of musical composition involving atonality, namely serialism and the 12-tone row.

The 12-tone method, developed by Arnold Schoenberg, avoids assigning importance to any single note by replacing the traditional system of tonality with a structure where all 12 tones are "related only to one another."1

In traditional tonal music, compositions are organized around a central pitch or "tonic," which creates a hierarchy where certain notes serve as focal points or goals. Schoenberg sought to move away from this, as he felt the old basis of tonality was being overstretched. By using a "basic set" or 12-tone row—an ordered sequence of all 12 pitches of the chromatic scale—the method ensures that no single note predominates.231

To maintain this equality, the system requires that all 12 notes must be presented before any can be repeated. By systematically preventing any note from serving as a musical goal, the 12-tone technique effectively obliterates traditional harmonic hierarchies, allowing the pitches to function independently of a single tonal center.423
