supports: Peru , officially the Republic of Peru, is a country in western South America. It is bordered in the north by Ecuador and Colombia, in the east by Brazil, in the southeast by Bolivia, in the south by Chile, and in the west by the Pacific Ocean. Peru is an extremely biodiverse country with habitats ranging from the arid plains of the Pacific coastal region in the west to the peaks of the Andes mountains vertically extending from the north to the southeast of the country to the tropical Amazon Basin rainforest in the east with the Amazon river. Chile, officially the Republic of Chile, is a South American country occupying a long, narrow strip of land between the Andes to the east and the Pacific Ocean to the west. It borders Peru to the north, Bolivia to the northeast, Argentina to the east, and the Drake Passage in the far south. Chilean territory includes the Pacific islands of Juan Fernández, Salas y Gómez, Desventuradas, and Easter Island in Oceania. Chile also claims about of Antarctica, although all claims are suspended under the Antarctic Treaty. Ecuador, officially the Republic of Ecuador (which literally translates as "Republic of the Equator"), is a representative democratic republic in northwestern South America, bordered by Colombia on the north, Peru on the east and south, and the Pacific Ocean to the west. Ecuador also includes the Galápagos Islands in the Pacific, about west of the mainland. HornbostelSachs or SachsHornbostel is a system of musical instrument classification devised by Erich Moritz von Hornbostel and Curt Sachs, and first published in the "Zeitschrift für Ethnologie" in 1914. An English translation was published in the "Galpin Society Journal" in 1961. It is the most widely used system for classifying musical instruments by ethnomusicologists and organologists (people who study musical instruments). The system was updated in 2011 as part of the work of the Musical Instrument Museums Online (MIMO) Project. The Charangón is a small lute - like fretted stringed instrument , of the charango family . Its general shape and construction are very similar to the charango , but it is larger and is typically pitched 3 or 4 diatonic intervals lower ( a `` 4th '' or a `` 5th respectively ) than a standard charango . The overall length varies from 70 to 80 cm , and the string length between 40 and 50 cm. The '' re `` charangón ( a '' 5th `` below a standard charango ) is typically tuned : do - do , fa - fa , la - LA , re-re , la - la ( cc , ff , aA , dd , aa ) where the '' la `` ( '' a `` ) is '' concert a `` ( between 415 and 450 Hz ) . Note that this will play a D minor 7th chord with the open strings . ( In the above example , the '' la `` is the course closest to the floor in normal right - handed convention ) . The tuning above is re-entrant , so that the '' do `` of the 5th course is only one whole tone below the '' re `` course . See the charango for details of this tuning arrangement . Other charangons are typically tuned with the same pattern , but may be either a whole tone up or down , or even a 4th lower . Sometimes courses other than the middle course have octave strings ( typically a lower octave than shown ) . It is bigger than the Charango , hence the ' ón ' ending on the name denoting the charangón 's larger size . String instruments, stringed instruments, or chordophones are musical instruments that produce sound from vibrating strings when the performer plays or sounds the strings in some manner.  Argentina, officially the Argentine Republic, is a federal republic in the southern half of South America. Sharing the bulk of the Southern Cone with its neighbor Chile to the west, the country is also bordered by Bolivia and Paraguay to the north, Brazil to the northeast, Uruguay and the South Atlantic Ocean to the east, and the Drake Passage to the south. With a mainland area of , Argentina is the eighth-largest country in the world, the second largest in Latin America, and the largest Spanish-speaking one. The country is subdivided into twenty-three provinces (singular "provincia") and one autonomous city ("ciudad autónoma"), Buenos Aires, which is the federal capital of the nation as decided by Congress.
  The provinces and the capital have their own constitutions, but exist under a federal system. The charango is a small Andean stringed instrument of the lute family, which probably originated in the Quechua and Aymara populations in post-Columbian times, after European stringed instruments were introduced by the Spanish in the times of the colony. The instrument is widespread today throughout the Andean regions of Ecuador, Bolivia, Peru, northern Chile and northwestern Argentina, where it is a popular musical instrument which exists in many variant forms. Lute can refer generally to any string instrument having the strings running in a plane parallel to the sound table (in the HornbostelSachs system), more specifically to any plucked string instrument with a neck (either fretted or unfretted) and a deep round back, or more specifically to an instrument from the family of European lutes. Bolivia (; ), officially known as the Plurinational State of Bolivia, is a landlocked country located in western-central South America. It is bordered to the north and east by Brazil, to the southeast by Paraguay, to the south by Argentina, to the southwest by Chile, and to the northwest by Peru. One-third of the country is the Andean mountain range, with one of its largest cities and principal economic centers, El Alto, located on the Altiplano. Bolivia is one of two landlocked countries (the other is Paraguay) that lie outside Afro-Eurasia. Bolivia is the largest landlocked country in the Americas. A fret is a raised element on the neck of a stringed instrument. Frets usually extend across the full width of the neck. On most modern western fretted instruments, frets are metal strips inserted into the fingerboard. On some historical instruments and non-European instruments, frets are made of pieces of string tied around the neck.
