Theatrical props are objects used on stage during a performance to enhance storytelling and create a believable environment. These items can range from simple objects like books and chairs to more elaborate pieces like swords or furniture. Props help actors convey their characters' emotions and actions, making the performance more engaging for the audience. Props are typically categorized into two types: hand props and set props. Hand props are items that actors carry or interact with, such as cups or weapons, while set props are part of the stage design, like lamps or paintings. Both types play a crucial role in bringing a play or performance to life.
