Fundamentals of classical harmony in the context of the XVIIIth century world outlook
The author of the article notes that chords with the interval structure of thirds are the basis of classical harmony, and its fundamental element was the triad. In our days, the triad (as well as other chords) is to be interpreted in highly specialized and technological aspect; world-outlook component of the triad has been underestimated. Hence it seems appropriate to consider the triad (and the interval of thirds being its structural basis) in the context of the world outlook of the different time. The change of the third’s status and its inclusion in the generally accepted number of consonances that occurred in the XVIIIth century is considered to be the consequence of new scientific and artistic aspirations for studying of man and nature. The third being an imperfect consonance has become one of the leading means conformably to music language that are assist to represent the imperfection of the terrestrial world. The triad consists of two thirds as the opposite elements in acoustic and semantic relations. The sum of these imperfect consonances is the perfect consonance of the fifth; so the image of unity and contradiction of high and low, heavenly and earthly, divine and human sources is formed. In the researcher’s opinion the triad can be viewed as a sound image of harmony of the world, analogous to such universal ancient symbols as the hexagram or the Taoist one-in-two unity of Yin and Yang.
