One of the oldest wind instruments comes from the desert of Northern Australia. It’s called a did geridoo . Native Australians make them for important celebrations. First,they cut a hollow branch from a eucalyptus tree. Then,they clen it make a mouthpiece and paint pattems on it. The sound of the didgeridoo is not only strange and beautiful but also great for dancing and singing. It only produces one note but a skilful player can use it to create an exciting rhythm.
