In it, a dominant seventh chord (in red) is handled conservatively, "prepared and resolved as a suspension, clearly indicating its dissonant status." Īudio playback is not supported in your browser. Renaissance composers conceived of harmony in terms of intervals rather than chords, "however, certain dissonant sonorities suggest that the dominant seventh chord occurred with some frequency." Monteverdi (usually credited as the first to use the V 7 chord without preparation ) and other early Baroque composers begin to treat the V 7 as a chord as part of the introduction of functional harmony.Īn excerpt from Monteverdi's "Lasciatemi Morire", Lamento d'Arianna (1608) is shown below. The V 7 chord is found almost as often as the V, the dominant triad, and typically functions to drive the piece strongly toward a resolution to the tonic of the key.Ī dominant seventh chord can be represented by the integer notation relative to the dominant. It was the first seventh chord to appear regularly in classical music. The dominant seventh is perhaps the most important of the seventh chords. Similarly, this chord also occurs on the seventh degree of any natural minor scale (e.g., G7 in A minor). In Roman numeral analysis, G 7 would be represented as V 7 in the key of C major. In this chord, F is a minor seventh above G. For instance, in the C major scale, G is the fifth note of the scale, and the seventh chord built on G is the dominant seventh chord, G 7 (shown above).
