Last night I just had a blast! I kept it fun. One speech still eludes me, but, other scenes made up for it. I felt on my voice again. Why? Partly, it's still 'luck' for me, not entirely technique. But, I did warm up better, not only doing all my warm up exercises--going through the routine--but taking my sweet time at them, starting slowly, sipping the air up the channel rather than gulping or pushing it upward. I grounded myself physically, taking at least ten minutes just for awareness, without 'doing' anything. I did all this at home so I could relax in privacy. There are a couple of people out there--yeah, yeah, you know who you are!--who keep reminding me that such meditation can be crucial, but I too often skip over it. Last night, I didn't, and it helped.
The entire cast connected better, too. You could tell during the group warm up, an hour before curtain, that we were going to have a tighter show, whereas during Friday's anemic group warm up, you knew we would flail. Though it didn't help to have five nights off, either. That long stretch makes getting back into the world of Shakespeare a challenging task.
update: I edited from this post a couple of sentences that sounded like I was picking on one group of actors rather than on all of us, hence the heat, in comments to this post.
