O, you are well tuned now!
But I’ll set down the pegs that make this music,
As honest as I am.
– William Shakespeare
Othello, Act 2, Scene 1. Speaking to himself, Iago uses a music metaphor to tell the audience of his plan to ruin Othello’s happiness. Having just seen Othello and Desdemona kissing, he vows to destroy their love, so foreshadowing events to come.
