Theater of the Mind is a concept where storytelling and imagination create vivid mental images without visual aids. It often involves audio formats, such as radio dramas or podcasts, where sound effects, music, and voice acting engage the listener's imagination, allowing them to visualize scenes and characters. This technique has roots in radio broadcasting and oral storytelling, emphasizing the power of sound to evoke emotions and create immersive experiences. It encourages active participation from the audience, as they interpret and visualize the narrative in their own unique way, making each experience personal and distinct.
