Answer :
They are different because in performances you see the action and in books you don’t
Many performances originally start as written stories. Similarly, many written stories are eventually turned into performances. However, the two mediums still have a lot of differences that need to be highlighted. Performances are originally designed as scripts. These tend to include all instructions that the actors and crew need to follow, such as tone of voice and facial expressions. In written texts, this is left to the imagination of the reader. Moreover, written texts need to be very detailed when it comes to setting and mood, as the reader needs to be able to imagine all this on his own. On the other hand, during a performance, this is conveyed through the acting.
