Theatrical effects are techniques used in live performances to enhance storytelling and create a more immersive experience for the audience. These effects can include lighting changes, sound effects, and stage props that help convey emotions or set the mood. For example, spotlights can highlight a character's importance, while soundscapes can evoke a specific atmosphere, such as a bustling city or a serene forest. Additionally, special effects like smoke machines or pyrotechnics can add excitement and drama to a production. These elements work together to engage the audience's senses and make the performance more memorable. Overall, theatrical effects play a crucial role in bringing a script to life on stage.
