When you can no longer blow the basic tone on the didgeridoo, it can indicate a leak, crack or hole in your didgeridoo. However, you can very easily fix your didgeridoo with beeswax. When you discover a crack or hole near the mouthpiece, it will be difficult to get another sound out of your didgeridoo. A crack or hole at the end or bell of the didgeridoo will have little to no influence on the didgeridoo tone. The solution is to close the leakage which you can do very simply with beeswax. The advantage of beeswax is that it moves with the shrinking and expansion of the wood of the didgeridoo. Moreover, the aboriginal people from Australia also repair their didgeridoos in this traditional way
