I’d presented it before but I can’t remember which post it was in. I’m attaching an image of the description and one of the Didgeridoo.
It’s the one I play in my latest post « Musiques Elisabeth ».
I’m giving you the link where Greg (DidgeridooPassion) plays it, you’ll see more playing possibilities with this Didgeridoo than with my somewhat « grainy » or « organic » way of playing.
