Final answer:
After the soliloquy in Act 3, Scene 1, Macbeth speaks in the form of a dialogue, which involves conversation between characters, as opposed to a monologue or soliloquy.
Step-by-step explanation:
After the soliloquy in Act 3, Scene 1, Macbeth speaks in the form of a dialogue. A dialogue is a conversation between two or more characters, which contrasts with a soliloquy where a character speaks their thoughts aloud when alone on stage. In the case of Shakespeare's plays, the dialogue after a soliloquy typically resumes the interaction between characters, involving exchanges that move the plot forward.
In Shakespeare's time, plays often featured shifts between poetic forms like iambic pentameter and prose. This shift can indicate a character's social status or mental state. Macbeth, written in a mixture of these styles, sees characters of nobility often speak in verse, while commoners and moments of intense emotion or madness may be conveyed in prose.
