A pit orchestra is a type of orchestra that accompanies
performers in musicals, operas, and other shows involving music.
The terms was also used for orchestras accompanying silent
movies when more than a piano was used.  In performances of
operas and ballets, the pit orchestra is typically similar in
size to a symphony orchestra, though it may contain smaller
string and brass sections, depending upon the piece. Such
orchestras may vary in size from approximately 30 musicians
(early Baroque and Classical Opera) to as many as 90-100
musicians (Wagnerian Opera). However, because of financial,
space, and volume concerns, the musical theatre pit orchestra is
considerably smaller (at most 20-30 musicians, including not
more than ten string players). Typically, pit orchestras play in
a lowered area in front of the stage called an orchestra pit.
Inside the pit, the conductor stands towards the stage and with
his or her back towards the audience to coordinate the music
with the actions of the singers, dancers and acto
