Do you have any notes for me? If you have spent any time in the theater, or in film or television production, or have an actor in your family, or hope to be an actor, this question will have a familiar ring. Actors always ask for notes on their performance, and they will take them from just about anyone. While people in other pursuits tend not to ask for performance ratings, actors demand them. Ron Marasco's Notes to an Actor grew out of the actor's profession-which, the author notes, is such a mysterious art. It is learned by experience, trial and error, and by succeeding and failing.
