Their dances are a national feature, and a great company of young warriors performing a solemn war dance is a most impressive sight. One of their chief instruments is the 'Marimba' or 'Tyanbilo,' a form of harmonium. The keys are bars of wood called Intyari, of graduated size. These are suspended by strings from a light wooden frame, either resting on the ground, or hung round the neck of the player. Between every two keys is a wooden bar crossing the centre bar to which the keys are attached. On each key two shells of the fruit known as the Strychnos McKenzie, or Kaffir Orange, are placed as resonators, one large and one small. The use of resonators is to increase and deepen the sound. The Marimba is played with drum-sticks of rubber, and the tone is good and powerful.

Another form of Marimba is popular amongst the natives of Guatemala, in Central America. Its construction is much that of a rough table, the top being formed of twenty-eight wooden bars or keys, from each of which hangs a hollow piece of wood, varying in size; these take the place of the resonating shells of the Zulu Marimba. The instrument is usually about six and a half feet long, by two and a half wide, and the keys are struck by hammers topped with rubber. Three performers often play together with great skill. This form of Marimba is also met with amongst the natives of Costa Rica.
African instruments are as a rule very noisy, their chief use being to alarm the enemy in war-times. An amusing story is told of Sir Samuel Baker, the explorer. When quartered for a time near the native town of Masinda, where dwelt the King of the Unyori, he was startled one evening, when the air was perfectly still, by the deep tone of a Nogara or native drum. This, ceasing as suddenly as it had begun, was followed by a terrific burst of sound, thousands of human voices yelling like maniacs and endless horns playing their loudest, besides the clashing of everything that could be persuaded to make a noise. Calling for his dragoman, or guide, Sir Samuel inquired what all this meant, and was gravely informed that it was all for his benefit, that he might be thoroughly frightened and quit the neighbourhood. The leader forthwith sent an order to the bandmaster of his regiment to assemble his men and make them play their very loudest, after which the clamour from the town speedily came to an end.

A tribe called the Niam Niam make a drum like a wooden horse, which is beaten on all sides at once, and certainly fulfils the condition of noise. Many tribes use a rattle, or 'Sanje,' which has the merit of simplicity, being merely a gourd filled with pebbles. The negroes of the Soudan play cymbals made of two thin plates of iron, after the plan of saucepan-lids, with handles of leather, whilst the Ashantees have a love for the clanging of brass pots, either banged together or struck with sticks; and some of the Congo tribes use a rude kind of bagpipes.
It must be remembered that the natives have not only human beings and wild beasts to scare, but believe in and dread a vast army of evil spirits, who they think must be kept at a distance and prevented by terrifying noises from exercising their powers.
