4. Four or Full Stage

Behind the wings that bound Three are another pair of wings, set
an equal number of feet back, which serve as the boundaries of
"Four." But, as there are rarely more than four entrances on any
stage, Four is usually called "Full Stage."

In Full Stage are presented all acts such as acrobatic acts, animal
turns, musical comedies, playlets and other pretentious acts that
require deep sets and a wide playing space.

5. Bare Stage

Sometimes the very point of a playlet depends upon showing not the
conventional stage, as it is commonly seen, but the real stage as
it is, unset with scenery; therefore sometimes the entire stage
is used as the playing stage, and then in the vernacular it is
called "Bare Stage." [1]

[1] The New Leader, written by Aaron Hoffman and played for so
many years by Sam Mann & Company, is an excellent example of a
Bare Stage act.

On the opposite page is a diagram of the stage of Keith's Palace
Theatre, New York City. A comparison of the preceding definitions
with this diagram should give a clear understanding of the vaudeville
playing stage.
