C. · Greek diatonic genus: a seven-tone scale from ancient Greece. · Greek chromatic genus: a seven-tone scale from ancient Greece. · Greek enharmonic genus: a seven-tone scale from ancient Greece. · Pythagorean: a twelve-tone scale dating from 600 B. C. This scale is derived by tuning twelve pure perfect fifths upward and adjusting the octaves downward. This leads to some pure intervals and some very impure intervals. · Just (major chromatic): a twelve-tone scale.
