First of all read through the passage to be acted. Then choose who will play each person, animal or divine being in the story. Imagine that a cameraman has taken shots of the major events in the plot. Go through the plot arranging yourselves into each one of these 'frozen pictures'. When each person has learnt their moves you can begin the performance.
Someone narrates the story from the beginning until they have described the first frozen picture.
The narator then waits till the actors have taken these positions for this first snapshot of the action. She than says 'curtain up'. The 'audience', who have had their eyes shut since the begining of the performance are now allowed to open then. The narator then says 'curtain down' and continues with the story til the next frozen picture. And so the story progresses.
