14:18:21, the supermajor triad or septimal major triad, is a triad in the 7-limit sometimes used in place of a major triad. It is the inversion of 6:7:9, the septimal minor triad or subminor triad. The supermajor triad, unlike the 4:5:6 major triad, is utonal. Due to the more complex 9/7 interval above the root, it may sound less consonant than 6:7:9, similarly to how the 10:12:15 minor triad is generally considered less consonant than 4:5:6.
