A didgeridoo is one of the oldest woodwind instruments in the world. It is from Australia. It is made from a Eucalyptus tree. It’s hollow inside because of termites! There is beeswax on top of the mouth piece. Other Didgeridoos might not have beeswax on the mouth piece because it would be a perfect size. Some tones are high and some tones are low. Longer Didgeridoos have a deeper sound. Shorter Didgeridoos have higher sound. Didgeridoos are from the Australian Aborigine tribes, who play loads of beautiful music and have cool hairstyles!
