There is not always a mouthpiece of beeswax to be put on the didgeridoo. Sometimes the wooden mouthpiece on the didgeridoo is already in good shape and does not need to be changed. When the nozzle is too large, you can use beeswax to make the wooden mouthpiece smaller by sculpting a mouthpiece on it, as it were. This is easy to do yourself and done in 10 minutes. If the nozzle has a rough surface, a little beeswax on the nozzle can also offer a solution.
