That is a crucial distinction in what we do. Drama, music, dance and other "arts" have much to contribute and teach us about the process of learning the sounds of language, but I am more and more convinced that the often excessively "dramatic events" in the pronunciation lesson (and pronunciation instructors tend to be irrepressible performers, themselves) can ultimately be counterproductive, just as Wyeth observed: the event overpowers and undermines the "art" and impact of the action.
Our work should be as thoroughly moving and touching . . . as it is uneventful!
