Until Windworks it was always my understanding that the Yoga/Wedge breath was designed to create high air pressure which then resulted in the wonders of double C and beyond. But as we now know it is shape that changes pitch, and that Greg doesn’t use any body activation when demonstrating the high range and the videos of Jim Manley clearly show that he doesn’t need anything but a low slow deep breath to play with his incredible range. So I too support the petition to hear what Greg has to say about the role of the Yoga/Wedge breath in relation to the Windworks process and psychology.
