How is drama created in Act 3, Scene 3, of Shakespeare's 'Othello'?

First, we must consider this scene in relation to the rest of the play. This comes right in the middle, and pinpoints the moment Othello is transformed from a jealous husband to Iago's puppet. In this alone we can see a clear dramatic movement.Now we have a framework in which to answer the question we must perform some close analysis of the language to support an argument. There are a few moments you could choose to discuss, such as Cassio's sly exit; Desdemona's pleas to Othello; Iago's dialogue with Othello; and, finally, the dropping of the handkerchief. It is important not to try to cram all these into your answer, but to choose what you think is most pertinent to creating 'drama'. For example, you may focus on the exchange between Iago and Othello at the end of the Scene. Iago spurs Othello on, not with long, persuasive speeches, but with short, simple prompts, which work to madden Othello. A good way to begin constructing an argument is to ask yourself questions, such as: 'what is the effect of Iago's short interjections?' From this you can launch an analysis of Othello's responses, which echo back Iago ('think', 'think, my lord?', 'Think, my lord!') and finally culminate in a long, sprawling speech. This repetition creates dramatic tension between the characters, as the dialogue becomes unnatural, and is heightened by the anger of Othello's long speech. In this way, from a few essential lines you can begin to construct a strong argument rooted in the language of the play.
