Thank you for the replies!
John, you mention pulling the mouthpiece out to check for a sympathetic buzz. I notice I can hardly ever get the mouthpiece not to buzz when I pull it out, which I guess would indicate synthetic oscillation…
Been messing with lots of articulations and some lead pipe playimng. How else can I work on this sympathetic buzz? Can anyone point me back toward the videos that Greg talks in depth about it?
Thanks again!
