It will be seen that this song ends with a chord of three tones; a triad, in other words. It will also be seen that each of the tones in the triad (with the exception of e) has been sounded more than once in the preceding melody. In fact, with the exception of d, all the tones of the melody are constituent tones of the triad. After singing these tones in melodic sequence, or one _after_ the other, it was surely a most natural procedure to sing them _at the same time_, so that they should sound together. Thus the triad was quite naturally produced. Drayton, who visited the Tonga Islands some seventy years after Forster, also mentions the fact of their ending some of their songs with a well-defined triad. But whereas the triad in the song noted by Forster is minor, that spoken of by Drayton is a major triad. In either case the fact is sufficiently remarkable. In the narrative of the Wilkes exploring expedition we find a song noted in which use is made of the harmonic intervals in the accompaniment of a melody. The song was obtained at the Tonga Islands about 1840. In its use of harmony it is one degree in advance of the song collected by Forster, although not so interesting melodically: [Illustration: Music] At first the bass note makes a fifth with the principal melodic note. Later the third is added, making the complete major triad. It is also worth noting that these harmonic bass tones are in a slightly different rhythm from the melody and preserve an independent character as an accompaniment to the melody. Perhaps the most striking instance, however, of the conscious use by savages of concordant musical intervals is afforded by the following little song noted by the traveller Forster as having been sung by the original inhabitants of New Zealand: [Illustration: Music] To have sung this melody in thirds, to have ended it in unison, and then to have gone back to the thirds again was certainly a most remarkable feat for the savage mind to accomplish, and decidedly points to conscious intention rather than mere accident. While the knowledge and the development of the science of harmony is one of the fruits of European civilization, and as a science is well-nigh confined to Europe exclusively, we still must admit that whereas primitive man had no knowledge of harmony he had a feeling for it, and that this feeling led him, though somewhat blindly, to the attainment of certain fundamental harmonic intervals. These intervals he evidently valued and used consciously. It is certainly of interest to note that a germ or suggestion of harmony existed in the primitive mind; that this element, as well as the other elements of music, has a natural basis. V
