<P> For example, in the C major scale (white keys on a piano, starting with C), the dominant is the note G; and the dominant triad consists of the notes G, B, and D . </P> <P> In music theory, the dominant triad (3 - note chord) is a major triad, symbolized by the Roman numeral V, if it is within the major diatonic scale (for example G-B-D in C major). It is, however, a minor triad, denoted v, if it is within the minor diatonic scale (for example G-B ♭ - D in C minor). In the minor scale, the dominant triad is often substituted with a major triad, by sharpening the second note, which is a minor third from the dominant note, into a major third, since the major third from the dominant is the leading tone for the minor scale . For instance, in G-B ♭ - D, the B ♭ is sharpened to B natural (B ♮), since B ♮ is the leading tone for the C minor scale . See: harmonic minor scale . </P> <P> A dominant seventh chord is a chord built upon the dominant of a major diatonic scale . It contains a major triad and a minor seventh of the root of the triad . An example is G in C major: G-B-D-F, with G being both the dominant of C major and the root of the major triad G-B-D, and F being the minor seventh of the root . In a general context, the dominant seventh is denoted V . </P> <P> As defined by the 19th century musicologist Joseph Fétis the dominante was a seventh chord over the first note of a descending perfect fifth in the basse fondamentale or root progression, the common practice period dominant seventh he named the dominante tonique . </P>
