Since 1996, alejandro blau developed a concept with which he introduces children and adults the world of the didgeridoo. This includes the construction of a didgeridoo:

When we are making a didgeridoo, we proceed as the Aboriginals in Australia:
We use a pipe, bought in a construct market and which is suitable for a didgeridoo.
As a "city kid" we cut our pipe to the desired length, paint the pipe and finish with wax to a didgeridoo with mouthpiece.
During the construction alejandro blau let the kids know what he was told by aboriginals, storys about playing the didgeridoo, some playing techniques.
When ready with the own didgeridoo, we practice together creating a song of our own and learn to play as a group. So listening, concentrating, give other parts importance and give own part importance are some of the teachment children get.
