Since I am still in high school and haven't really officially trained in acting, I am not up to par with the names and terminologies used by jrb and touchme. However, from what I've observed in my childhood/adolescent acting experiences, I've been exposed and drawn more toward the English school, and I agree with most of what is said here.
During rehearsals, unless I am walking through a scene quickly to help the lighting designer (ie, no lines, just standing in place), I always give it my all during rehearsals. By giving it your all, you are able to explore your full yet developing work before it is shipped out to the public.
During rehearsals (and performances), even if I go through a scene five times in a row, I never perform it the same way. What my character's going for, and the overall attitude I perform are both the same, however, I find new nuances every time I go through the scene.
jrb...are there any books you'd suggest to help me research the methods/terminologies you've mentioned?
