noun. A well located directly downstage of the Apron in which the orchestra sits. Many modern proscenium theaters have mechanically or hydraulically operated lifts in their orchestra pits which allow the floor to be raised or lowered to increase stage area, or lower the orchestra below floor level. Such lifts typically have four preset stops: basement (minus ~15') , pit (minus ~6'), audience (minus ~3'), and stage (0'). Often referred to simply as "The Pit."
