How does a key scene from a novel contribute to the work as a whole?

A key scene imitates an important idea that contributes to the conflict in the plot.

Explanation:

The key scenes in a novel are inflicted by the author to convey his central idea and the intended message to the audience effectively. These scenes include the characters engaging themselves in the rising actions that leads to the conflicts and these conflicts lead to the climax and the falling action eventually. The resolution to these actions comes as a conclusion to the fiction through which the narrator relates the "universal theme" to the readers. Thus, the key scene focuses on the central events of the plot that drives the story throughout and leads it to the denouement.
