Scene study is the practice of taking a written scene apart, making specific choices from the text, and testing those choices with another actor. It connects script analysis to behaviour.
You look at the circumstances, relationships, objectives, obstacles, shifts, and actions in the scene. Then you put the analysis on its feet. If your character needs forgiveness, for example, the work is not to look sorry. It is to pursue forgiveness from this particular person and let their resistance change how you go after it. Good scene study includes another pass after feedback, because the first attempt shows what your preparation actually produced. The point is not to discover one correct performance. It is to build a process that helps you make clear choices while staying responsive to the person in front of you.
