A dramatic tool
used for exposition
and general mood
-setting. Makes use of one or more anonymous
players who discuss the general state of affairs
in the kingdom
. They may communicate with the principal
characters as well.
The Greek chorus is still used today. The example that springs to my mind first is the Newscaster who comes on to conveniently discuss an arrest/murder/election that affects the plot.
Depending on who's directing, members of a Greek chorus may hold multiple roles during a performance.
