Since the ancient days of Thor and the invention of Swedish meatballs, kulning — a traditional Swedish herding call — has been a staple of the country’s culture. Used to call livestock down from the mountains, it is usually performed by women, since they traditionally tend to these animals.

With her unique voice and her beautiful blonde hair, this woman looks like an angel singing in the snow.

According to Jonna Jinton, the woman in the video, the kulning took months of practice to master. Her voice needed time to develop. After seeing this footage, it’s clear that all of her efforts paid off.
