The most primitive musical utterances are usually confined to a narrow range. Seconds and thirds are the intervals most frequently used. The songs of the Terra del Fuegians, for instance, do not usually exceed the limits of a third. The song just quoted from Arnheim is, it will be noted, with the exception of the ornamental quirks, confined to the range of a second. The most limited songs in regard to range of intervals, however, appear to be the songs of the Andamanese Islanders. M. V. Portman in a paper on Andamanese music published in the _Journal of the Royal Asiatic Society_, says: 'The only notes in use in their songs are the following, and in this order: The leading note 1/4 sharp, the tonic, the tonic 1/4 sharp. The whole range of notes is therefore not equal to a superfluous second.’[3] The savage mind, being incapable, for the most part, of the development of a musical idea, is satisfied by an incessant repetition of the same phrase. Here is a song of the Caribs as noted by Théodore de Bry. While it is comprised within the interval of a small second, it was repeated sometimes for an hour at a time, with what monotonous effect we can well imagine: [Illustration: Music] Another Carib song, comprised within the interval of a fourth, is here given. A similar song from Polynesia is also given for purposes of comparison. The two songs are remarkably similar; in fact, almost identical. The geographical separation of the Caribs and the Polynesians is so great as to have made intercommunication almost beyond the bounds of possibility. How, then, can the similarity be accounted for? Apparently only by assuming that peoples who live in similar conditions, and whose minds are in a similar state of development, may express themselves in a similar manner: [Illustration: CARIBS] [Illustration: POLYNESIAN] Germs of the principle of contrast may be found in both the above songs. A second phrase or musical motive has been invented which is sung alternately with the first, thereby relieving the sense of monotony. This was certainly a great step in the development of primitive music. The invention of a second musical phrase, and the contrasting of it with the first, was the unconscious beginning of musical form. For contrast is the basic principle of form in music. The following song from Samoa shows this principle of the contrasting of musical motives very clearly. The two motives are sung by different groups of persons: [Illustration: Music] The above is a tune in which the contrasting phrases are of equal length, and recur with great regularity, but many tunes are found in which the contrasting motives, or melodic particles, follow each other with whimsical irregularity, their relative position and recurrence following no law but the feeling of the singer at the moment. Such is this tune of the Macusi Indians of South America:
