Identify and explain the four elements of drama that don't exist in short stories or novels.

The answer to this question depends on if the play is
being read or if it's being staged.  The latter is its intended purpose, so I'll focus
on "live drama" versus "fiction."

1.  Live drama uses a
live audience.  Actors on stage feed off the energy in the crowd, and intensifies the
mood.  Fiction has readers, but no live audience.

2.  Live
drama is more fluid and easily revised; novels and short stories are fixed--cannot be
changed.  The director of a play can take out a line or even a scene if it does not work
from performance to performance.  A fiction writer cannot revise so easily or
quickly.

3.  Live drama is collaborative; fiction is
solitary.  In drama, there are actors, directors, and choreographers, musicians, and
techs.  It's obviously much more of a team production.  Fiction is composed in
solitude.

4.  Live drama is meant to be heard and seen, not
read.  Fiction is obviously meant to be read.  So, drama is a audio-visual
performance-based art, and fiction is much more contemplative.
