Note the increasingly long sentences as Macbeth delves deeper into the horror and chaos of the contemplated deed. The first complete sentence is nearly five lines. The next sentence is over nine lines. And if, for the purpose of analyzing this speech, we consider the semicolons and colons to serve the same purpose as periods (which they could, depending on the actor), then we see even more clearly the escalation of sentence length. While Macbeth begins with a simple five-word phrase (\"He's here in double trust\") he culminates with a 36-word sentence (ending with \"drown the wind.\").");
