Final answer:
Stage directions and dialogue in the play 'Macbeth' contribute to plot progression and character development. Macbeth's dialogue reveals his guilt and moral conflict post-murder, whereas the First Murderer's dialogue and Lady Macbeth's responses are more pragmatic, showcasing a contrast in depth of emotion and moral engagement.
Step-by-step explanation:
To answer the question, stage directions and dialogue in a play are pivotal in advancing the plot and developing the characters. In Macbeth, the dialogue sheds light on Macbeth's psychological turmoil and moral decline. For instance, when Macbeth exclaims, “Methought I heard a voice cry 'Sleep no more! Macbeth does murder sleep'”, the audience can sense his overwhelming guilt and descent into paranoia following Duncan's murder. The repetition of 'sleep no more' emphasizes his tormented state, unable to find peace. In contrast, the First Murderer's dialogue is more straightforward and focused on the practical aspects of the act of murder, revealing a lack of the same depth of moral conflict that Macbeth experiences.
Comparatively, Lady Macbeth's use of dialogue, such as when she tells Macbeth to “Go get some water, And wash this filthy witness from your hand”, demonstrates her practical approach to the aftermath of the crime and her initial lack of remorse, which is a stark contrast to Macbeth's distress. These dialogues not only further the action but also offer insights into the character's inner workings, building tension and development throughout the plot. The use of dialogue in plays differs from novels, where actions and thoughts are often narrated; here actors interpret actions based on the dialogue, imbuing it with their own emotions and reactions to bring the characters to life.
