Since the ancient days of the Vikings, a traditional Swedish herding call known as kulning has been a staple of the country's culture (much like Ikea meatballs). The breathtaking song, usually performed by women, was used in the olden days to call livestock down from the mountains.
Watch as singer Jonna Jinton steps into a lush field on a cloudy summer night and calls a herd of cows with her hypnotizing voice.
Well, I wasn't expecting that ending. Apparently, kulning is like Barry White for cows. Who knew?
