In the past, it was common to use herding calls to gather ones flock of cows together.
But how would cows react to herding calls today? Swedish Jonna Jinton decided to try.
"It was the a bright summer night, and I decided to go out and called out to the cows," she writes on YouTube. "I thought that maybe there was something deep within them that made them remember the sounds from ancient times, back when people sung towards them from afar."
The clip, which has reached 1.6 million views on YouTube, is truly enchanting. Just have a look at how the cows react to Jonna's magical voice - this is just beautiful!
