They also possess a rude banjo-like instrument from which comparatively fair music could be produced, but the Bushmen are content to strum it without method, and take the music as fortune sends it. A drum completes the list of Bushman instruments; it is sometimes played with sticks and sometimes with the fist. It can be heard at a considerable distance. In contrasting these two extremes of African races, it is singular to remark, that the superiority in music, if there be any, must be conceded to the lower race. We find much that is curious and worthy of note in the music of those mysterious tribes of central Africa, who have so recently become known to us through the researches of Schweinfurth, Stanley, and Baker. Among the best known of these tribes, may be mentioned the Nyam-Nyams, a set of most inveterate cannibals, whose very name comes from the sound of gnawing at food, and was given them on account of their man-eating propensities. Their chief musical instruments are mandolins or small harps of four strings each, drums (mostly of wood,) bells of iron, whistles and pipes. Many of these instruments are very symmetrically formed, and tastily carved, for in wood, iron, and clay designing the Nyam-Nyams are very expert. Schweinfurth thus describes their music,[212]—“They have an instinctive love of art. Music rejoices their very soul. The harmonies they elicit from their favorite instrument, the mandolin, seem almost to thrill through the chords of their inmost nature. The prolonged duration of some of their musical productions is very surprising.” Piaggia has remarked that he believed a “Nyam-Nyam would go on playing all day and all night, without thinking to leave off either to eat or to drink,” and although quite aware of the voracious propensities of the people, it seems very probable that he was right. One favorite instrument there is, which is something between a harp and a mandolin. It resembles the former in the vertical arrangement of its strings, whilst in common with the mandolin, it has a sounding-board, a neck, and screws for tightening the strings. The sounding board is constructed on strict acoustic principles. It has two apertures; it is carved out of wood, and on the upper side it is covered with a piece of skin; the strings are tightly stretched by means of pegs, and are sometimes made of fine threads of bast, and sometimes of the wiry hairs from the tail of the giraffe. The music is very monotonous and it is difficult to distinguish any melody in it. It invariably is an accompaniment to a moaning kind of recitative which is rendered with a decided nasal intonation. “I have not unfrequently seen friends marching about arm in arm, wrapt in the mutual enjoyment of the performance, and beating time to every note by nodding their heads.”
