One choice made in the book Othello is the use of foreshadowing. Foreshadowing adds suspense to the drama and keeps you wondering what's going to happen, which is why a lot of authors use it. Another thing that I noticed Shakespeare did is that the lines seem to be either a block of text, or merely a short sentence. Lots of commas and semicolons are also used, which keeps the text flowing along instead of it having a slow speed.
