Folk music from the Andean region. The general public has been able to get acquainted with music from the Andes in two ways. In the first place, it was the Bolivian music groups that provided shopping malls and train stations with exotic musical wallpaper with pan flute, guitar and drum. Then there is the hit that Simon and Garfunkel had with their interpretation of the Peruvian classic El Condor Pasa. Andean music has its origins in the Inca era, which stretched from roughly 1200 to 1500 across Bolivia, Ecuador, Peru and northern Argentina and Chile. In Andean music the traditional languages and instruments from that time still occupy an important place. The stringed instruments introduced by Spaniards have also been given a place in the line-up. Guitar, charango (Bolivian lute), drum, flute and pan flute form the basis of Andean music, which increased in popularity in the second half of the twentieth century. Chilean folk groups such as Inti Illimani and Quilapayún incorporated many influences from the music of the high mountains into their music.
