The all-trichord hexachord is a concept from music theory, particularly in the context of 20th-century music, and is associated with twelve-tone serialism. The term "hexachord" refers to a collection of six pitches. In this case, the all-trichord hexachord consists of all possible combinations of three-note chords (trichords) derived from a six-note set.
