Theatre of ancient Greece The plays had a chorus from 12 to 15[10] 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 skenÃ©. The coryphaeus was the head chorus member who could enter the story as a character able to interact with the characters of a play.
