What is the author's tone in Six Characters in Search of an Author by Luigi Pirandello?

There is a lighter tone to this. A less obvious device in the play is Pirandello's use of laughter to lighten the audience's confrontation with this frustrating collision of reality and illusion. The play is not easily seen as humorous on the page, but in production the humor can be rich and is certainly essential in order to reassure the audience that their inability to easily distinguish between reality and illusion is an inevitable but ultimately comic part of human existence.
