A
play is meant to bring a story to life visually. Props and costumes help bring
context to a play that the audience would otherwise miss without them. It’s
especially true when dealing with a play that is set in a different time period
and unfamiliar setting to the audience. The play “Trifles” is set in a time
period that is very different from the one we live in now. Without props and
costumes to portray this setting accurately it would be difficult for an
audience to fully grasp the setting. The dialogue itself gives hints to a
different time period but it might not be blunt enough to fully explain this to
an audience. If the audience is not aware of the setting they will not
understand they story fully. You could rely on the actors to portray accurate
speech and mannerisms but this could still be inadequate.
There
is also a lot of interaction with props written in the playwright. If actors in
the play did not have these props to work with they would have a difficult time
portraying their actions to the audience. I doubt it would be too difficult for
experienced actors to work with a blank set, but the audience can only work
with what they hear or see. If there was no set to portray the bleakness and
emptiness of the house, the audience might not be able to immerse themselves in
the story deep enough to appreciate it.
