Improvisational comedy, often called improv, is a form of live performance where comedians create scenes and dialogue on the spot, without a script. This spontaneous style relies on the performers' creativity, quick thinking, and ability to collaborate with one another. In improv, audience suggestions often inspire the content, making each show unique. Comedians use various techniques, such as character development and storytelling, to engage the audience and build humor. Popular formats include short games and longer scenes, showcasing the performers' skills in adapting to unexpected situations.
