The play Macbeth by William Shakespeare is organized into 5 acts â the so-called Five-Act Structure. The plot is chronological and there arenât flashbacks. Each act contains several scenes; an example is act three which contains six scenes. The play starts with a prologue scene given by the three witches who occasionally appear between major scenes to foreshadow or comment on events, e.g. act 1, scene 3 (the drums).
