The didgeridoo is a musical instrument that comes from the Aboriginal people of Australia. It is made from a hollowed out log that is about as tall as a grown-up person. When a person plays the didgeridoo, they blow into one end of the log and make a low, vibrating sound.
To make the sound, the player needs to blow air into their mouth and then push it into the didgeridoo. They also need to use their lips to vibrate and make the sound. The player can change the pitch of the sound by moving their tongue and changing the amount of air they blow into the didgeridoo.
People have been playing the didgeridoo for thousands of years. It was used by the Aboriginal people in ceremonies and celebrations. Today, people all over the world enjoy playing the didgeridoo and listening to its unique sound.
