Flabiol is a musical instrument that is used in some parts of the world, especially in Catalonia in Spain. It is a type of flute that is played by blowing into it and using your fingers to cover and uncover holes along its length to create different notes.
Imagine blowing into a long stick with a bunch of little holes along it. Depending on which holes you cover with your fingers, you can make different sounds and notes. The flabiol is like that, except it's made out of wood and has a special shape that helps it make beautiful music.
People who play the flabiol usually play it in groups with other instruments, like a drum or a guitar. They play traditional songs and dances, and it sounds really cool when they all play together.
Sometimes, the flabiol is even used in big festivals and celebrations, where lots of people gather together to have fun and dance. So, if you ever hear someone talk about playing a flabiol, you'll know it's a type of musical instrument that makes beautiful music!
