France, sorry for posting yet another post but it just so happens that I’m at a point in the course (again) that is supper relevant to this thread.

After posting the above post, I watched the very next video in the course: Andante Fundamentals – Leadpipe Transition (or something like that)

In that video, Greg really explains how the tongue fits in and the jaw (chin), etc. I think it would be super helpful to you to watch that again and obviously it’s better to hear this stuff straight from Greg than from me or other peers who are still developing.

Hope this is helpful to you.

Best,

John
