Griboyedov, as well as the vaudeville by A. S. Griboyedov and P. A. Vyazemsky "Who is a Brother, Who is Sister, or Deception after Deception". The goal lies in the analysis of similar genre models: light comedy and vaudeville – a variety of salon comedy. The key method of research is the motif-imagery analysis, which reveals a number of common a number of motifs and allowed examining the images of heroes. The comparative method is used for establishing the common and different between the indicated genre models.

The conclusion is drawn that vaudeville and light comedy are closely interrelated with a wide variety of genres: anecdote, fable, comic opera, interact, melodrama, and often serve as a means for conducting literary polemics. The external distinguishing characteristic of vaudeville is the presence of a verse. Despite the similarity of the fabula. it is worth noting that the light comedy rather tends towards high literary tradition; the external actable comism is reduced, and expressed through the speech manner of the heroes, witty dialogues, and aphoristic speech. The heroes are usually secular young people. The scene is also limited to secular living rooms and manor estates. Vaudeville in turn, is not restricted by the framework of secularism; its heroes can be officers, actors, servants, serfs, etc. Moreover, comism of the status of heroes is enhanced by external effects: buffoonery, multiple outfit changes, rapid and unpredictable narrative arc.
