Read the excerpt from act 5, scene 8 of The Tragedy of Macbeth. Macduff has just killed Macbeth. The stage direction at the beginning of the excerpt has been expanded.

Re-enter MACDUFF, with MACBETH’S head in one hand and MACBETH’S crown and sword in the other.

Macduff. [To MALCOLM.] Hail, king! for so thou art: behold, where stands
The usurper’s cursed head: the time is free:
I see thee compass’d with thy kingdom’s pearl,
That speak my salutation in their minds;
Whose voices I desire aloud with mine:
Hail, King of Scotland!

All. Hail, King of Scotland!

a triumphant mood
a sense of unease
a feeling of contempt
a respectful tone
