In theatrical script writing, sketch stories, and poetry, a vignette is a short impressionistic scene that focuses on one moment or gives a trenchant impression about a character, idea, setting, or object. This type of scene is more common in recent postmodern theater, where less emphasis is placed on adhering to the conventions of theatrical structure and story development. Vignettes have been particularly influenced by contemporary notions of a scene as shown in film, video and television scripting. It is also apart of something bigger than itself. Like a vignette about a house belongs to a collection of vignettes or a whole story such as The House On Mango Street by Sandra Cisneros.
A blog can provide a form of vignette.
