What is the author's style in Private Lives by Noel Coward?

While Coward is known for his witty dialogue, his work is relatively short on quotable "punch-lines" or one-lmers, the kind of which define the comedic style of writers like playwright Neil Simon (The Odd Couple) and filmmaker Woody Allen (Annie Hall), The humor of Private Lives depends greatly on its expert stagecraft and carefully-balanced construction. In his introduction to the anthology Play Parade, Coward modestly describes the play as "a reasonably well-constructed duologue for two experienced performers, with a couple of extra puppets thrown in to assist the plot and provide contrast." This self-deprecating assessment points to two of the playwright's strengths: his awareness of the abilities of the "experienced performers" with whom he worked, and his attention to contrast and symmetry.
