Some jaw releases...
Why should you care about releasing your jaw? Because we all tend to carry around some tension in these muscles. And as with residual muscular tension in other areas of the body, it just feels better to release some of it! But even more importantly, from an accent learning perspective, it's much easier to take on a new pattern—the posture of a new accent—if we start from a place that's less bound by our habitual pattern.
Enjoy!
