Leave it to the Norwegians and Swedes to take a way to call cattle in high mountain pastures and turn it into a genre of music.
This originally functional call has become a distinctive style of music, which someone online has endearingly described as “opera for cows.” The Norwegian composer Edvard Grieg was apparently inspired them. Kulning is seeing a bit of a revival at the moment thanks to a few modern artists like Jonna Jinton and Christine Hals. The latter provided some kulning for the soundtrack of Disney’s Frozen; you might have also heard kulning if you’ve watched the TV series Vikings.
