I took my didgeridoos out in public last Sunday and the general consensus was that I'd made the mouthpieces too big. Drats. So today I melted the beeswax with my hair dryer and reshaped them. I'm letting them cool now. I still can't figure out the circular breathing to save my life so it's discouraging. Especially when I see a kid on youtube that must be all of 16 playing like he was born with a tube in his mouth. Let me see if I can find that for you.
