Leading-tone triad A leading-tone chord is a triad built on the seventh scale degree in major and the raised seventh-scale-degree in minor. The quality of the leading-tone triad is diminished in both major and minor keys. For example, in both C major and C minor, it is a B diminished triad (though it is usually written in first inversion, as described below).
