About 15,000 years ago some indigenous Northern Australians decided that they needed a more efficient way of talking to each other than just shouting a lot.
And blowing into a long cylindrical tube proved to be just what was needed and seriously useful fun – the dawn of the didgeridoo.
Trumpets and bagpipes were invented at about the same time. The ancient Greeks used the trumpet in battlefield communication to devastating effect.
The way you can tell that your didgeridoo is better than everyone else’s didgeridoo is to blow into it and see how far the sound goes.
