In the beginning, some lines were 10s, but most were 11s or 12s. This is due to her talking quickly since she was upset that Macbeth lacks the personality to go after his promised crown. However, about 13 lines later when Lady Macbeth finally stops rambling and reaches her “Hie thee hither” line, the rest of the monologue remains in a consistent pentameter. This is because Lady Macbeth has finally calmed down and strategically talks out a plan for her and her husband. However, the very last line tears away from the consistency of the lines preceding it. It has only seven beats because the servant walks in and Lady Macbeth’s monologue ends. However, this line is important because Lady Macbeth started off the monologue by saying “Glamis thou art, and Cawdor; and it shalt be What thou art promised”, and ends off her monologue with the similar message saying that Macbeth will be exactly what he is promised because both fate and the witches said so, and nothing will change
