A Schoenberg hexachord is a concept introduced by the composer Arnold Schoenberg, which plays a key role in his twelve-tone technique and theory of music. Specifically, it refers to a collection of six pitches that form a set, serving as one of the building blocks for melodies and harmonies in his compositions.
