Singer Jonna Jinton shows off her bovine bel canto, with a technique like nothing you’ve ever ‘herd’.

Humans have harnessed the power of the voice since ancient times, both for the creation of art and for more utilitarian purposes – like herding cows. Jonna Jinton demonstrates that one doesn’t need to preclude the other, however, using the ancient, beautiful Swedish singing technique of “kulning” – a herding call – to lure a herd of cows to her in a video that has become a viral hit on YouTube. Similar to yodelling, Kulning uses high frequencies to project sound over long distances and was used in medieval times by – mostly female – cow herders to call their animals.
