Tragicomedy; Chekhov was known for his blending of tragic and comic genres.

Protagonists 

Voynitsky, Astrov, Sonya

Setting (time) 

Turn-of-the-century Russia

Falling Action 

Chekhov does not make use of the classical Aristotelian plot line, in which rising and falling action comprise an immediately recognizable climax, catastrophe, and denouement.

The play unfolds in the time of the present.

Tone 

Tragi-comedic

Foreshadowing 

Again, because Chekhov makes use of such an unconventional plot structure, often driven by indirect action, there is little foreshadowing.
