BOLIVIA
In BOLIVIA , traditional dances are accompanied by American Indian musical instruments including PAN PIPES.  These vertical flutes have a long history—pottery examples have been found which date back to 200 BC. 

Today panpipes are usually made of canes that are lashed or glued together.  They have no finger holes; different notes are achieved by the player blowing across the pipes which are cut to different lengths.  A mixture of the pentatonic and European diatonic scales is common to much of the folk music of the area.
