<P> The plays had a chorus from 12 to 15 people , who performed the plays in verse accompanied by music , beginning in the morning and lasting until the evening . The performance space was a simple circular space , the orchestra , where the chorus danced and sang . The orchestra , which had an average diameter of 78 feet , was situated on a flattened terrace at the foot of a hill , the slope of which produced a natural theatron , literally `` seeing place '' . Later , the term `` theatre '' came to be applied to the whole area of theatron , orchestra , and skené . The coryphaeus was the head chorus member who could enter the story as a character able to interact with the characters of a play . </P>
