how does the production of Oedipus maintain the elements of original Greek tragedy?

(masks, chorus, music, religious ritual, etc.)

The production of Oedipus the King was well done, if a little odd or awkward in places. The face-paint on Oedipus and a few of the chorus members mimicked the masks of old Greek theater, as well as the idea of a closed theater where no one leaves the stage. That element was the most odd and gave me a good taste of what Greek theater would have been like, given the setting in which greek plays were performed, the ancient amphitheater.

The music and chorus provided an additional element of original Greek tragedy. Most renditions of old plays that I've seen have either removed the chorus entirely or incorporated the chorus into the play as speech, when in all likelihood they were actually sung. The music and dance provided key interludes and helped to explain back story and advance the overall plot.
