Relating to, composed of, or characterized by the number six or groups of six.
From Greek 'hex-' (six) + '-adic' (relating to). This mathematical and philosophical term has ancient roots and became more standardized in modern mathematics and logic.
In music, hexadic thinking appears in the twelve-tone system—twelve divides perfectly into two groups of six, which composers like Schoenberg used to create entirely new musical languages.
