Any performance is a two-way communication process. The performer addresses the audience with words and actions; the audience in turn actively responds to the performer. If this performance deviates too far from audience expectations of the familiar folk artifact, they will respond with negative feedback. Wanting to avoid more negative reaction, the performer will adjust his performance to conform to audience expectations. "Social reward by an audience a major factor in motivating narrators..." It is this dynamic feedback loop between performer and audience which gives stability to the text of the performance.
