The tones produced by these early musical instruments, however, even those of the stringed instruments and their vocal accompaniment, by no means, of course, form harmonic music. On the contrary, harmony is an achievement of the succeeding age; it is here foreshadowed in only imperfect beginnings. Such beginnings, however, may everywhere be discerned in the records that we have of the melodies of the Soudan negroes and the American races. Nevertheless, most of the records that are as yet available are still of doubtful value. The auditor is too prone to find in them his own musical experiences. For reliable data we must wait until, following the beginnings that have already been made, a greater number of such natural songs will have been objectively recorded by the aid of the phonograph. As yet we can only say that, if we may judge from their musical instruments, the Africans surpass all other natural peoples in musical talent. Their melodies ordinarily move within the range of about an octave, whereas those of the North American Indians seldom pass beyond a sixth. The fact of this small tonal compass will itself indicate that the melody of all natural peoples tends to very constant rhythms and intervals. The latter, moreover, show some similarity to those with which we are familiar. The chief characteristic of these songs, however, is their tendency toward repetition. One and the same motive frequently recurs with tiresome monotony. The melodies thus reflect certain universal characteristics of primitive poetry as they appear in the songs of the Veddahs and of other pretotemic tribes.
