Hi Gary,

Happy to hear that I am not the only one struggeling. I can move my jaw forward but even a slight forward change gives me trouble with my joints. So my strategy for now is:

– I try to keep my jaw as relaxed as possible and as much possible ‘in’ the joint (so not forward)
– I roll out my bottom lip slightly AND support it with my tongue anchored on it (this is actually what I have found useful from the TCE trumpet school, but it is not easy to do and you need some time to be able to play with your tongue forward.) This forms a bit of a cussion where i do not need to use the jaw so much and then I can rest my top lip on my bottom lip (alignment) and blow upward a little

it is stil in experimental phase though so my final stand on this i can not give you yet.

Good luck. W.
