Powerful Breathing and Maximizing Lung capacity by William Thoren
Breathing effectively will reduce a lot of stress when learning any new techniques on the didgeridoo. Due to the larger mouth piece size required for playing these techniques, it is important that one has good control of breath when moving up to something that requires more air then normal.
Side vs Front playing by William Thoren
Many didgeridoo players play out of the side of their mouth because the clarity of the drone sound is easier to achieve. Often the front sounds softer and not as rich in the early stages of playing. From my experience, with practice, frontal playing allows for equal clarity once mastered and opens up a larger range of possible control. Mastering frontal playing is a lottle more difficult at first but has huge payoffs in the end. Making the switch to playing out of the front is possibly the most important foundation to learning this technique.
