- Aztec cluster of bells
It is noteworthy that these yotl are found figured in the picture-writings representing the various objects which the Aztecs used to pay as tribute to their sovereigns. The collection of Mexican antiquities in the British museum contains a cluster of yotl-bells. Being nearly round, they closely resemble the Schellen which the Germans are in the habit of affixing to their horses, particularly in the winter when they are driving their noiseless sledges. - Aztec drums
As regards instruments of percussion, a kind of drum deserves special notice on account of the ingenuity evinced in its construction. The Mexicans called it teponaztli. They generally made it of a single block of very hard wood, somewhat oblong square in shape, which they hollowed, leaving at each end a solid piece about three or four inches in thickness, and at its upper side a kind of sound-board about a quarter of an inch in thickness. In this sound-board, if it may be called so, they made three incisions; namely, two running parallel some distance lengthwise of the drum, and a third running across from one of these to the other just in the centre. By this means they obtained two vibrating tongues of wood which, when beaten with a stick, produced sounds as clearly defined as are those of our kettle drums. By making one of the tongues thinner than the other they ensured two different sounds, the pitch of which they were enabled to regulate by shaving off more or less of the wood. The bottom of the drum they cut almost entirely open. The teponaztli was generally carved with various fanciful and ingenious designs. It was beaten with two drumsticks covered at the end with an elastic gum, called ule, which was obtained from the milky juice extracted from the ule-tree. Some of these drums were small enough to be carried on a string or strap suspended round the neck of the player; others, again, measured upwards of five feet in length, and their sound was so powerful that it could be heard at a distance of three miles. In some rare instances a specimen of the teponaztli is still preserved by the Indians in Mexico, especially among tribes who have been comparatively but little affected by intercourse with their European aggressors. - Chines King
According to their records, the Chinese possessed their much-esteemed king 2200 years before our Christian era, and employed it for accompanying songs of praise. It was regarded as a sacred instrument. During religious observances at the solemn moment when the king was sounded sticks of incense were burnt. It was likewise played before the emperor early in the morning when he awoke. The Chinese have long since constructed various kinds of the king, one of which is here engraved, by using different species of stones. Their most famous stone selected for this purpose is called yu. It is not only very sonorous but also beautiful in appearance. The yu is found in mountain streams and crevices of rocks. The largest specimens found measure from two to three feet in diameter, but of this size examples rarely occur. The yu is very hard and heavy. Some European mineralogists, to whom the missionaries transmitted specimens for examination, pronounce it to be a species of agate. It is found of different colours, and the Chinese appear to have preferred in different centuries particular colours for the king. - Chinese kin-kou
The kin-kou (engraved), a large drum fixed on a pedestal which raises it above six feet from the ground, is embellished with symbolical designs. A similar drum on which natural phenomena are depicted is called lei-kou; and another of the kind, with figures of certain birds and beasts which are regarded as symbols of long life, is called ling-kou, and also lou-kou.
