ANDEAN MUSIC: Mistakenly called "Inca Music", present-day Andean folk music is the product of centuries of cultural and ethnic intermixing. The wind and percussion instruments indigenous to the Andean world existed in Pre-Colonial America hundreds of years before the advent of the Incas (1200-1500 A.D.) Archaeological excavations have proven that certain musical instruments in the Andean highlands were being played well before the birth of Christ. The Incas were, however, responsible for the highest development of Pre-Colonial Andean music. Unprecedented in its domination of an expanse of territory stretching over the boundaries of present-day Bolivia, Peru, Ecuador, northeastern Chile, and northwestern Argentina, the Inca dynasty created an empire that both imposed itself and incorporated various cultures.
