We all know we are meant to sing with a relaxed jaw but is yours relaxed? Really? Have you checked it lately?
If you're having trouble with a note or passage, check your jaw. Most of us hold tension there - especially when we're "working hard." Don't assume just because you know your jaw "should" be relaxed, that it is. Check it. And then - gently relax it. There now, isn't that better?
