action and energy associated with the images varies, from recording to recording. stuff like fingers on keys or strings and 'chest' or 'mouth' in vocals, the woodiness and power of a cello, skin of the drums, the sense of suddenness to the music......stuff that seems to cross the border of realism. when it is a natural part of the image bringing it more alive i call that action. movement, intensions.
I don't quite understand. Are you talking about visual images in your head? You've told us you don't go to many live performances. Do you watch a screen with orchestras performing? I know DG sells access to live performances that you can watch on tv. I have a John Williams DVD of him conducting the Berlin Philharmonic (?); it has excellent visuals of musicians playing their instruments.
