The Andes is the world's longest exposed mountain range, the longest being the underwater Ocean Ridge.[1]. It forms a continuous
chain of highland along the western coast of South America. It is over 7,000 km (4,400 miles) long, 500 km (300 miles) wide
in some parts (widest between 18° to 20°S latitude), and of an average height of about 4,000 m (13,000 ft).
The Andean range is composed principally of two great ranges, the Cordillera Oriental and the Cordillera Occidental, often
separated by a deep intermediate depression, in which arise other chains of minor importance, the chief of which is Chile's
Cordillera de la Costa. Other small chains arise on the sides of the great chains. The Cordillera de la Costa starts from
the southern extremity of the continent and runs in a northerly direction, parallel with the coast, being broken up at its
beginning into a number of islands and afterwards forming the western boundary of the great central valley of Chile. To the
north this coastal chain continues in small ridges or isolated hills along the Pacific Ocean as far as Venezuela, always leaving
the same valley more or less visible to the west of the western great chain. The mountains extend over seven countries: Argentina,
Bolivia, Chile, Colombia, Ecuador, Peru and Venezuela, some of which are known as Andean States.
The Andes mountain range is the highest mountain range outside Asia. The highest peak, Aconcagua, rises to 6,962 m (22,841
ft) above sea level. The summit of Mount Chimborazo in the Ecuadorean Andes is the point on the Earth's surface most distant
from its center, because of the equatorial bulge. The Andes cannot match the Himalayas in height but do so in width and are
more than twice as long.
The musical tradition of the Andes are still alive inspite of over five hundred years of Spanish colonialism. Some of he
ancient ways remain intact. Yet others have merged with those brought by the Spanish conquest.
The Music
The musical traditions of the Andes can be, in general terms, categorized in three styles: Pre-Columbian, mestizo, and contemporary.
