A vessel flute is like a musical instrument that you can blow into and make sounds. Just like when you blow air into a balloon and it makes a squeaky noise, blowing into the vessel flute makes a different sound depending on how you play it.
The vessel flute is a special kind of instrument because it is made out of a hollowed-out object, like a bone or bamboo cane, that has holes or notches cut into it. These holes or notches affect the airflow and produce different sounds.
To play the vessel flute, you hold it up to your mouth and blow gently into it. Then you cover and uncover the holes with your fingers to create different notes. It's kind of like playing a recorder or a kazoo, but with a different shape and sound.
People have been making and playing vessel flutes for thousands of years in different parts of the world. Some cultures even believe that vessel flutes have special powers and can communicate with spirits.
Overall, a vessel flute is a unique and fun instrument that you can play by blowing into it and controlling your fingers to make different sounds.
