The domesticated bones are much thinner walled n ya have to be a little more careful with them while out n about to keep from cracking or chipping them but other then that , the sounds they produce are identical. The biggest difference I've found has been the circumference of the end of the smallest bone, the one ya stick in yer mouth to make the actual sound through, the small the hole the higher the pitch, the bigger the hole the deeper the pitch. While I was makeing them there was a tone range that was the sweet spot to me, after putting them all together I'd cluck n file a bit on the end a little at a time until the tone was where I liked it. Then just rounded the edges so it was comfortable on the lip when useing-just some thoughts YMHS Birdman
