The aah-ooh is critical for me in remembering to tighten the aperture corners from the corners while relaxing the top and bottom lip, letting the top lip vibrate freely in the air column. When I do that, everything is golden and I get good sensations and an open easy feeling and resonant sound and increased flexibility / speed.

I often catch myself overthinking and trying too hard and overblowing and clamping, but I think I’m getting it… again…

Great video!
