William Barton : Power Exercise
This technique was fundamental for me in learning how to control the back pressure of big mouth pieces and big bores. It may sound funny when you practice but the sound is not important, it is literally lifting weight with your cheeks and lungs. be conscious of your positioning while practicing as to not hurt or strain your neck ( swivel from the hip and not neck and back if your going deep under). if you have a traditional eucalyptus didgeridoo that is not coated on the inside I would not recommend using this as it may crack from the saturation when it dries.
