To end this "series", we have the summation question - does it make a difference? The easy answer is yes. Of course, every person you sing for will have different priorities in their listening, but I think being physically and dramatically involved will never be a negative. And, as I've said in other posts, being involved in your character keeps you from being "too" involved with your voice. In other words, you can get out of your own way!!
I will explore this idea of getting out of your own way some more in upcoming posts.
