The Business Audience as Chorus

The character of the audience in a business presentation is found somewhere between a traditional citizen audience and a Greek chorus. Like a Greek chorus, the business audience is a group that is made up of individuals. Together they bring institutional knowledge to the presentation. They represent the culture and interests of all executives and employees. They serve as a foil to the presenter and senior managers in the audience are often eager to participate and be heard.

A skillful presenter can leverage the chorus attributes of their business audience to advantage: challenging them, wooing them, and letting them give voice to and become advocates for the message of the presentation: averting tragedy rather than courting it.
