Kulning is a type of singing that comes from Scandinavia, which is a place in Europe where it's very cold and snowy. It's a special way of singing that is often used by farmers to call their cows home from the fields.
So, imagine you're a farmer in Scandinavia and you live on a big farm with lots of cows. When it's time for the cows to come in and be milked, you need to call them back to the barn. But, you don't have a phone to call them, and shouting might not work because the fields are very big and the cows might not hear you.
This is where kulning comes in! Kulning is a special way of singing that is very loud and high-pitched. It sounds a bit like a cross between singing and screaming, but it's actually very beautiful. When you sing kulning, you use your voice to make a sound that travels very far and can be heard over long distances.
So, as a farmer, when it's time to call your cows home, you would start singing kulning. You would sing a special melody that the cows recognize and that tells them it's time to come in. The melody might be a bit different from farm to farm, but the cows would always understand it because they're used to hearing kulning.
Kulning is still used in Scandinavia today, even though we have phones and other ways of communicating. People like to keep the tradition alive and use it as a way of connecting to their heritage and history. It's also really fun to try, even if you don't have any cows to call!
