Hello little one! Do you know what ululation is? It's a big word that means making a loud, high-pitched noise with your voice. It's often used in some cultures as a way to express joy or celebration.
So, imagine you're at a party or a wedding, and lots of people are very happy and excited. Some of them might start to make a really loud, high-pitched noise by wiggling their tongues back and forth really fast while letting out a loud "ulululululululul" sound.
It might sound a bit like a howling coyote or a siren, but don't be scared - it's just a fun way for people to show their happiness and enthusiasm! Some people might even add clapping or drumming to make it even more lively.
Overall, ululation is just a way to express joy and excitement in a really loud and fun way.
