Didgeridoo Sound

The didgeridoo is manufactured based trunks hollowed out by termites. In Australia there are thousands of termite mounds, and it is estimated that there are 20 million termites per hectare, tirelessly building great mountains of earth and clay.
Termites burrow into trees, especially the eucalyptus, hollowing them out but not killing them.
The aborignal australians check the trees in the forest: if the termites have finished hollowing the wood out, the men will cut it down to make their valued instrument.
They clean it, removing the bark, and with an iron bar heated in a fire, they finish emptying the inside of the bough. The Didgeridoo is ready.
The musicians themselves are responsible for making and checking the sound of their instrument.
