Transcript of How the Didgeridoo Works

By Jarrod Faulkner How does the Didgeridoo work? So What's to know about the Didgeridoo? Thank You For Watching The traditional way that didgeridoos are made is a very interesting process. It is usually made by getting a eucalyptus tree that has been hollowed out by termites. It is then trimmed down and has it's trunk removed, and then a rim of beeswax is applied to the narrower end to work as a mouthpiece. How is it made? To play the didgeridoo, one must continuously vibrate their lips whilst exhaling. To keep the constant drone, one must use a special breathing technique called " Circular Breathing". This means to inhale through the nose whilst exhaling through the mouth. How is it played? The didgeridoo is common with other reedless wind instruments due to the players using their lips and breath to cause the air inside to vibrate at a frequent rate. The harder the players breathe, the bigger the vibration and the bigger the vibration is, the louder the sound. How does make sound? (Part 1) How does it make sound? (Part 2) When the didgeridoo is played, the sound waves travel backwards into the player's vocal tract, a resonator(sound detector) that amplifies and/or suppresses certain patterns. The frequency of the tract resonating depends on the shape of the tract and the position of the player's tongue. Most of the time during player the didgeridoo, the tract is actually moving backwards. http://www.cairnsunlimited.com/popups/images/w_didgeridoo.jpg http://www.aboriginalart.com.au/images/dg_p16.gif http://images.travelpod.com/users/jamiemeasures/1.1285449050.playing-the-didgeridoo.jpg http://www.phys.unsw.edu.au/jw/graphics/didjschematic.GIF Reference List: 1.
