Yelatáj Chos Woley
The yelatáj chos woley, yelataj chas woley or simply jelataj choz, is a musical bow which is characteristic of the Wichi culture in the South American Gran Chaco. Features The Yelatáj chos woley consists of two bows of tusca wood. The performer holds the end of one of the bows between his teeth and rubs that bowstring with the other. The musician's mouth acts as a resonator. Originally the bowstrings were made from peccary A peccary (also javelina or skunk pig) is a medium-sized, pig-like hoofed mammal of the family Tayassuidae (New World pigs). They are found throughout Central and South America, Trinidad in the Caribbean, and in the southwestern area of North A ... hair, vegetable fibers or other hair. When horses arrived with the Spaniards to America, instrument makers began to use the hairs from horse manes and tails. The dimensions of one listed at Musical Instrument Museums Online (MIMO) is 350 mmm long x 60 mm wide (bowstring to bow handle). Usage The yelatáj ch ...

Musical Bow
The musical bow (bowstring or string bow, a subset of bar zithers) is a simple string instrument used by a number of South African peoples, which is also found in the Americas via slave trade. It consists of a flexible, usually wooden, stick 1.5 to 10 feet (0.5 to 3 m) long, and strung end to end with a taut cord, usually metal. It can be played with the hands or a wooden stick or branch. It is uncertain if the musical bow developed from the hunting bow, though the San or Bushmen people of the Kalahari Desert do convert their hunting bows to musical use. Types of bow include mouth-resonated string bow, earth-resonated string bow, and gourd-resonated string bow. History There is speculation that the hunting bow may have been used as a musical instrument from as early as circa 13,000 B.C. Henri Breuil surveyed the Trois Frères in France caves and made an engraving that attempted to reproduce a c. 13,000 B.C. cave painting into a black-and-white lithograph engraving ...

Gran Chaco
The Gran Chaco or Dry Chaco is a sparsely populated, hot and semiarid lowland natural region of the Río de la Plata basin, divided among eastern Bolivia, western Paraguay, northern Argentina, and a portion of the Brazilian states of Mato Grosso and Mato Grosso do Sul, where it is connected with the Pantanal region. This land is sometimes called the Chaco Plain. Toponymy The name Chaco comes from a word in Quechua, an indigenous language from the Andes and highlands of South America. The Quechua word ''chaqu'' meaning "hunting land" comes probably from the rich variety of animal life present throughout the entire region. Geography The Gran Chaco is about 647,500 km² (250,000 sq mi) in size, though estimates differ. It is located west of the Paraguay River and east of the Andes, and is mostly an alluvial sedimentary plain shared among Paraguay, Bolivia, and Argentina. It stretches from about 17 to 33°S latitude and between 65 and 60°W longitude, though estimate ...

Catagonus Wagneri Closeup
''Catagonus'' is a genus of peccaries that contains the living Chacoan peccary and several extinct species. The genus has always been restricted to South America. Taxonomy ''Catagonus'' is notable in that the type species, '' C. metropolitanus'', is extinct; the living Chacoan peccary was first described in 1930 from subfossil remains, and only found alive by scientists in 1972 (an example of a Lazarus taxon). A 2017 study on the phylogenetic systematics of Tayassuidae species suggests that ''Catagonus'' should only contain ''C. metropolitanus''. The extinct narrow-headed peccary ''Catagonus stenocephalus'' (or ''Brasiliochoerus stenocephalus'') is an extinct species of peccary that lived in South America during the Late Pleistocene. Fossils have been found in Brazil, Argentina and Bolivia. It is commonly known as the narr ... ''(C. stenocephalus)'' should be moved into ''Brasiliochoerus'', while the Chacoan peccary, ''C. bonaerensis'' and ''C. carlesi'' should be placed in '' ...

Resonator (instrument)
Acoustic resonance is a phenomenon in which an acoustic system amplifies sound waves whose frequency matches one of its own natural frequencies of vibration (its ''resonance frequencies''). The term "acoustic resonance" is sometimes used to narrow mechanical resonance to the frequency range of human hearing, but since acoustics is defined in general terms concerning vibrational waves in matter, acoustic resonance can occur at frequencies outside the range of human hearing. An acoustically resonant object usually has more than one resonance frequency, especially at harmonics of the strongest resonance. It will easily vibrate at those frequencies, and vibrate less strongly at other frequencies. It will "pick out" its resonance frequency from a complex excitation, such as an impulse or a wideband noise excitation. In effect, it is filtering out all frequencies other than its resonance. Acoustic resonance is an important consideration for instrument builders, as most acoustic in ...
