Read the excerpt from act 3, scene 4 of The Tragedy of Macbeth . Macbeth is speaking to Lady Macbeth and preparing to join his guests at the banquet table. Macbeth: See, they encounter thee with their hearts’ thanks; Both sides are even: here I’ll sit i’ the midst: Be large in mirth; anon, we’ll drink a measure the table round. What mood does the alliteration in the phrase "they encounter thee with their hearts’ thanks” help create?
