The mixture of South American Indian, African and European cultures in PERU is reflected in their music.  The FLUTE was much cultivated in Peru and in fact its melancholy sound was so evocative that early Spanish religious authorities tried to prevent its use!  Music of the Incas is still performed among the populations of the high plateaux of the Andes .  This music is strongly pentatonic (5 note) with five modes (or scales) each taking one of these notes as its tonal center.
