It has been a month since this post. I have been marinating in the largo stage since that time. I have watched the fundamental videos again and again. The progress has been slow, but it has been significant, better sound, more relaxation. The mouthpiece has been moved down as noted above, and this change has helped. Yes, the mouthpiece wants to move up and over to the old position as I ascend.

In the shape-leadpipe video, another video called “synthetic or sympathetic” is referenced. Where do I find this video?
