I was just reading a post on circular breathing and I tried it myself.
I'm interested in how a musician like a clarinetist can maintain a constant dynamic when doing circular breathing. I find that my cheeks don't hold enough air so when I do circular breathing the air flow drops to a tiny amount before a new breath can push the dynamic back up again. It sounds very noticeable...I probably need to practice some more to smooth out the F dropping to ppp and back up to F again...
Any thoughts appreciated
