2. Encores: In some cases, particularly with music and dance performances, the audience may demand an encore, which means the performers return to the stage for an additional performance.
3. Booing: Booing is a form of expressing disapproval or dissatisfaction. It can occur if the audience feels the performance is of poor quality or if they disagree with the content.
4. Laughing: Laughter is a common response to comedy performances, but it can also occur in other contexts, such as when an unexpected or humorous moment happens during a serious play.
5. Silent and Attentive: In more formal theatre settings, audiences may be expected to be silent and attentive during the performance, showing respect for the performers and the art form.
6. Heckling: Heckling is a form of disruptive behavior where individuals from the audience make vocal comments or interruptions that distract or criticize the performers.
7. Standing Ovations: In exceptional cases, especially for remarkable performances or as a sign of great appreciation, the audience may give a standing ovation, where they stand up and applaud enthusiastically.
8. Participation and Call-Outs: In some theatrical performances, such as musicals, plays with audience involvement, or interactive shows, the audience may participate by singing along, responding to prompts, or even playing a part in the performance.
9. Etiquette: Many theatres have certain rules and expectations regarding behavior, such as turning off mobile phones, not talking during the performance, and refraining from any actions that could disturb the experience for others.
It's worth noting that these are just generalizations, and specific theatres and performances may have their unique traditions and expectations for audience behavior.
