Didgeridoo
When a tree is found and cut down, the part of trunk or branch that will be made into a didgeridoo is cut out. The bark is taken off, the ends are trimmed, and there is some shaping of the outside. It may be painted or left natural. A rim of beeswax may be put on to the mouthpiece end. Traditional instruments made by Aboriginals in Arnhem Land are sometimes fitted with a 'sugarbag'  mouthpiece. This is black beeswax from wild bees and has a its own special smell.
