The musician is likely to speculate what could have induced the Peruvians to adopt so strange a series of intervals: it seems rather arbitrary than premeditated.
If (and this seems not to be improbable) the Peruvians considered those tones which are produced by closing the lateral holes as additional intervals only, a variety of scales or kinds of modes may have been contrived by the admission of one or other of these tones among the essential ones. If we may conjecture from some remarks of Garcilasso de la Vega, and other historians, the Peruvians appear to have used different orders of intervals for different kinds of tunes, in a way similar to what we find to be the case with certain Asiatic nations. We are told for instance “Each poem, or song, had its appropriate tune, and they could not put two different songs to one tune; and this was why the enamoured gallant, making music at night on his flute, with the tune which belonged to it, told the lady and all the world the joy or sorrow of his soul, the favour or ill-will which he possessed; so that it might be said that he spoke by the flute.” Thus also the Hindus have certain tunes for certain seasons and fixed occasions, and likewise a number of different modes or scales used for particular kinds of songs.
Trumpets are often mentioned by writers who have recorded the manners and customs of the Indians at the time of the discovery of America. There are, however, scarcely any illustrations to be relied on of these instruments transmitted to us. The Conch was frequently used as a trumpet for conveying signals in war.
The engraving represents a kind of trumpet made of wood, and nearly seven feet in length, which Gumilla found among the Indians in the vicinity of the Orinoco. It somewhat resembles the juruparis, a mysterious instrument of the Indians on the Rio Haupés, a tributary of the Rio Negro, south America. The juruparis is regarded as an object of great veneration. Women are never permitted to see it. So stringent is this law that any woman obtaining a sight of it is put to death—usually by poison. No youths are allowed to see it until they have been subjected to a series of initiatory fastings and scourgings. The juruparis is usually kept hidden in the bed of some stream, deep in the forest; and no one dares to drink out of that sanctified stream, or to bathe in its water. At feasts the juruparis is brought out during the night, and is blown outside the houses of entertainment. The inner portion of the instrument consists of a tube made of slips of the Paxiaba palm (Triartea exorrhiza). When the Indians are about to use the instrument they nearly close the upper end of the tube with clay, and also tie above the oblong square hole (shown in the engraving) a portion of the leaf of the Uaruma, one of the arrow-root family. Round the tube are wrapped long strips of the tough bark of the Jébaru (Parivoa grandiflora). This covering descends in folds below the tube. The length of the instrument is from four to five feet. The illustration, which exhibits the juruparis with its cover and without it, has been taken from a specimen in the museum at Kew gardens. The mysteries connected with this trumpet are evidently founded on an old tradition from prehistoric Indian ancestors. Jurupari means “demon”; and with several Indian tribes on the Amazon customs and ceremonies still prevail in honour of Jurupari.
The Caroados, an Indian tribe in Brazil, have a war trumpet which closely resembles the juruparis. With this people it is the custom for the chief to give on his war trumpet the signal for battle, and to continue blowing as long as he wishes the battle to last. The trumpet is made of wood, and its sound is described by travellers as very deep but rather pleasant. The sound is easily produced, and its continuance does not require much exertion; but a peculiar vibration of the lips is necessary which requires practice. Another trumpet, the turé, is common with many Indian tribes on the Amazon who use it chiefly in war. It is made of a long and thick bamboo, and there is a split reed in the mouthpiece. It therefore partakes rather of the character of an oboe or clarinet. Its tone is described as loud and harsh. The turé is especially used by the sentinels of predatory hordes, who, mounted on a lofty tree, give the signal of attack to their comrades.
Again, the aborigines in Mexico had a curious contrivance of this kind, the acocotl, now more usually called clarin. The former word is its old Indian name, and the latter appears to have been first given to the instrument by the Spaniards. The acocotl consists of a very thin tube from eight to ten feet in length, and generally not quite straight but with some irregular curves. This tube, which is often not thicker than a couple of inches in diameter, terminates at one end in a sort of bell, and has at the other end a small mouthpiece resembling in shape that of a clarinet. The tube is made of the dry stalk of a plant which is common in Mexico, and which likewise the Indians call acocotl. The most singular characteristic of the instrument is that the performer does not blow into it, but inhales the air through it; or rather, he produces the sound by sucking the mouthpiece. It is said to require strong lungs to perform on the acocotl effectively according to Indian notions of taste.
The botuto, which Gumilla saw used by some tribes near the river Orinoco (of which we engrave two examples), was evidently an ancient Indian contrivance, but appears to have fallen almost into oblivion during the last two centuries. It was made of baked clay and was commonly from three to four feet long: but some trumpets of this kind were of enormous size. The botuto with two bellies was usually made thicker than that with three bellies and emitted a deeper sound, which is described as having been really terrific. These trumpets were used on occasions of mourning and funeral dances. Alexander von Humboldt saw the botuto among some Indian tribes near the river Orinoco.
