Alex, I downloaded the music as it's shown by abcnotation.com. Then I changed the key notation from F to C, since that seemed to make sense. Then I changed it from 5/4 to 4/4, and that also seemed to make sense.

But when I tried to set chords to it, I saw that it moves up and down the scale so much, that chords seemed fruitless. Yes, I spose you could play something is you only produced a chord at the beginning of a measure and if you held your mouth right. But if I were doing it, I would just use a singer and a drum.

But wait. Maybe you could use a drone. Think about that.
