Yes I accidentally learned how to play years ago when I went camping with some friends and we were stuck inside the tents for most of the time because it constantly rained so I taught myself how to play. I used water to learn how to circular breathe by filling my mouth and checks up with the water and slowly squeezing it out of my lips whilst breathing in through my nose. It's a great way to understand the concept of circular breathing. I've never actually owned a didgeridoo so I haven't played it in a while.

Oh beezwax for sure but Sticky-Tack/Tac 'n' Stik/Blue Tack (what ever you want to call it) is pretty good. It does get warm a little quicker than wax but it doesnt leave a slimy residue from the condensation of your breath.

I liked your 3 beat breaths and then a long exhale. It really gives it a rhythm.

Happy didging
