I have a mental sickness for the last 2-3 weeks, I fold in love with a melody and I have no idea what it is. I know that is some kind of 14-15 century Peruvian (?) ceremonial dance. Hypostatically it set to be somewhere in Inca world of the pre-Columbian America but it might be a wide guess. In the fragment I posted below the dance is being played by a full force of symphony orchestra and it make me absolutely horny!

Can somebody who has South America background could identify the melody?  I want more of it.
