Didgeridoo is made of a hollow wood and to manufacture it can be very simple or extremely complecated depending on the material used and on the way of carving the wood. The common materials used are various: bamboo and plastic, metal and clay, eucalyptus or any other type of wood. It must be pointed out that originally it was a wooden instrument actually made of eucalyptus. aborigines use trunks or branches hollowed by termites (termited) found in the bush, they just add a mouthpiece made of bee wax and decorate the instrument with paintings and carvings; of course these didgeridoos are the best in sound and carving, since termites hollow only "soft" eucalyptus wood leaving untouched the hardest part. So if you have an Australian termite colony and a good piece of eucalyptus you are ready to make yourselves your "original" didgeridoo:-) Instead, as far as "human" carving is concerned, some use big and long drills but only in case of a stragiht wooden piece, or some practice a less normal method, much slower but likely more effective: take an incandescent iron bar and press it in the wood until perforating it all along its length. Anyway, the most common method to proceed still remains the longitudinal cut of the branch and the following carving of the two inner parts that consequently will be reassembled by means of an expansion glue. As far as the bamboo is concerned, it is all much simpler as this wood is already naturally hollowed; even in this case one can make a longitudinal cut or break inner membranes near the knots beating strongly with a metal bar. The chipest method, producing low-quality didgeridoos (but good enough to start playing), consists of taking a plastic (or metal) hose and supply it with a mouth-piece. When using natural materials, it is very important the wood be well seasoned before carving it.

Dimensions:

Length determins didgeridoo basical note, it can go from 80 cm. up to 2.5 mt. with a diameter of 2-8 cm. While diameter cannot vary a lot, length can theorically be short or enormous; please note that beyond a certain length the breath needed and the infrasonic note will be enemies to sound listening, instead a too much short didgeridoo can produce the classical raspberry noise.
