| Re: Lower Jaw position
The best place for the lower jaw is somewhere under the upper jaw......
I had a trumpet teacher that played around with lower jaw position and came to a lesson hardly able to talk. He had somehow thrown his lower jaw out of socket. Those were exercizes that I stopped right away!
Let's look at what moving the lower jaw does: changes the alignment of the teeth, which changes the support surface behind the lips. This creates a need to angle the trumpet differently to equalize the pressure between the lips.
It also changes the path that your air takes to enter the mouthpiece, as your tongue has learned to work with the "other" geometry.
Depending on how much "overbite" that you had, bringing the lower jaw forward can also increase the size of usable oral cavity, unbalancing the pressure relationship on both sides of the lips (back pressure from the horn/mouthpiece support the lips on the outside, breath support on the inside. They must be balanced to be able to produce a sound!).
This is a pretty major change in embouchure, that brings a whole lot of other requirements with it. You will have to change many habits.
What do you think will get better? |
