5: Our Stages and Their Equipment

  • Page ID
  • Like all other art forms, theatre has developed its own specific terminology to describe
    its elements of stage craft and equipment. Many of these terms have been
    handed down through history. Some come to us from the earliest Greek theatres,
    others from Roman theatre, Renaissance theatre, and other theatre cultures from
    around the globe. In theatre, it is common for several different terms to be used to
    describe the same element, and each of these terms is generally deemed to be accurate
    and acceptable. For the student, this makes the vocabulary of theatre a bit of a
    challenge to absorb. It also means we should always strive to be specific and consistent
    in our use of terminology to ensure clear communication.


    Consider This
    Why is it important to sound like an expert? When working on a show, we rely on
    one another’s expertise to ensure the production is the best it can be. Choosing a collaborator
    means measuring the success of the project against that team member’s skill
    and their level of commitment. We all want to work with the most talented, dedicated
    artists, but also with people we can relate to and trust. Trust is always easier to establish
    with someone who speaks and acts like an expert in the field. Using correct terminology
    and demonstrating seriousness about your art will always help others instil trust
    in your ability.


    The most confusing terminology in common use for the theatre involves stage directions.
    In order for a production team to be able to reference what part of a stage
    they are discussing or for a director to talk to a performer about where they should
    be appearing on the stage, we need to have a set of coordinates to guide us. We refer
    to these as stage directions. For most, the tricky part is that they are from the perspective
    of the actor facing the audience. The major areas are downstage (left, right,
    and center), which is the edge of the stage closest to the audience; mid-stage (left,
    right, and center); and upstage (left, right, and center) which refers to the area furthest
    away from the audience. In larger theatres these major areas may be further
    divided to include a “left of center” and “right of center” as well. We are often in 

    the audience facing the stage when we refer to these coordinates and must remember
    to reverse our natural sense of direction. During early rehearsals stage managers
    note all of the actors stage movements, referred to as blocking, using this system
    of coordinates. This blocking is recorded into the script of stage manager’s prompt
    for production reference. Conversely, we also use the terms “house right” and
    “house left” when referring to the seating area of the auditorium as we face the
    stage. In arena theatres these directions are impractical, and many companies instead
    use a clock-face model to divide the playing area.



    Stage directions


    Of the terms we use to describe basic elements of a playing space, some relate
    most clearly to a proscenium style theatre, but can also be applied to other types
    of spaces. The area of the stage where the actor is visible to the audience is known
    as the playing area. Space outside the playing area where the audience’s view is
    blocked by scenery, curtains, or the proscenium arch is referred to as wing space and
    can be found both off-stage-left and off-stage-right of the playing area. In a proscenium
    theatre the area in front of the proscenium arch is referred to as the apron.


    In some spaces, all or part of this apron may be converted into an orchestra pit to
    house musicians for productions. Some theatres have a crossover—a hallway upstage
    of the playing area or in a basement below the stage that allows for passage
    from one side of the stage to the other unseen by the audience.


    A stage is occasionally equipped with removable panels to create an opening in the
    floor with access to a basement area. Handy for quick (dis)appearances, these are
    known as traps.


    A control booth or group of booths is usually found at the rear of the auditorium.
    This location allows the stage manager and lighting and sound operators to have
    the same perspective as the audience. Additional booths may be available for followspot
    operators or other technical needs. In some productions, you see sound operators
    at a live sound-mixing console in the seating area of the auditorium. This
    is done so they are able to hear the performance as the audience does rather than
    from the remote location of a booth or from behind a glass window.



    Above the stage, you commonly find a fly system or theatrical rigging. In a proscenium
    theatre the space above the stage is blocked from the audience’s view by the
    top of the proscenium arch. Depending on how high the ceiling is over the stage,
    you may be able to fly in rigged scenery to transform the stage setting. The area
    above the stage is referred to as the fly loft. At the top of the fly loft is a series of
    support structures known as the grid. From this grid structure a series of cables,
    pulleys, and ropes supports and moves the hanging elements. If the fly loft is twice
    as tall as the proscenium, then elements sized to fill the stage can be hidden above
    for later use. The draperies, scenery, lighting, and other production resources are
    rigged from this structure via ropes and cables. Modern theatres may be equipped
    with a counterweight system allowing for easier operation and movement of heavy
    rigged elements. When this is the case, a fly crew can move multiple drops or flying
    elements via locking control lines running along one wall of the stage house. This
    allows for large scenic transformations with minimal effort. Older theatres may be
    equipped with rope-set rigging where sandbags and tie-off cleats or a pin rail keep
    the flying elements under control. Most of these theatres place the pin rail about a
    story above the stage along one wall. This system allows for the flying of production
    elements as does the counterweight rigging system, although ropes must be carefully
    tied of by hand rather than simply locked in place.

    In both of these rigging systems the support or lift lines (whether rope or steel cable)
    are referred to by their length extending out from the head block as short, mid,
    and long lines. Some wider stage fly systems may require additional spaced lift lines.
    For rigging, a pulley (or sheave) is housed within in a block, aptly called a pulley
    Its job is to change the direction of the rope or line. Several pulleys can be
    housed in a single block to accommodate multiple lift lines. The pulley blocks directly
    above the short, mid, and long lines are referred to as loft blocks and are
    supported by the grid. In a rope-set system these lift lines run across the fly loft,
    through the head block, and down to the pin rail where they can be controlled.
    Heavy objects are balanced for lifting through the attachment of sandbags. In a
    counterweight system the lift lines are routed through the head block and then attached
    to a counterweight arbor, which is tracked to run vertically up and down the
    off-stage wall. This arbor is then loaded with weights using a loading bridge above
    the stage to counter the load rigged onto a batten, which is the horizontal pipe that
    the lift lines support, and to which scenery, lights, or drapery is rigged. The vertical
    travel of the arbor is then controlled by the fly crew through the use of a hand-line,
    which can be locked at any height via the rope lock. The hand-line (or purchase line)
    is attached to the arbor at the top and bottom. This line runs through the head block
    at the grid and under the tension block at the stage level. Some battens are capable
    of supporting the extra weight loads of lighting equipment. These are designated as
    electrics and may also be equipped with permanent electrical circuits for lighting

    Consider This
    Though the art of rigging has been a part of theatre for centuries, the kind of theatrical
    spectacles being created today require a special degree of safety oversight. We routinely
    lift extremely heavy objects above stages and must rely on careful engineering to keep our
    environments safe. Theatrical rigging standards have been developed for production, and
    experts should always be consulted when rigging safety is in question.


    Fly systems are designed to balance a heavy load hung from a batten so a single individual
    can move it without great effort. To “fly in” a batten is to bring it down
    toward the stage floor to be worked on. Conversely a batten is “lifted out.” It is customary
    to always announce to others working around you that a batten or “pipe” is
    “moving” when you are about to shift its position. This lets everyone know to be on
    alert for a changing environment and things may be coming in from above. If you
    are working with a fly system, you should always keep the load-in balance whenever
    possible to avoid run away lines and keep areas clear when work is being done
    Sometimes simply balancing a load is not enough for our purposes, and we must
    gain an advantage over the load for an individual to lift it. That is when we must employ
    a system of rope and pulleys to aid in lifting the load. You may be familiar with
    the power of a block and fall set from images of safes or pianos being hauled up into
    the windows of tall buildings. A block and fall set uses several blocks of pulleys to
    half the force of the weight of the load we need to haul, but does so by making us
    move twice the rope through the blocks. Adding more sets of pulleys to the system
    continues to reduce the force required to lift the load, but also increases the length
    of rope that must travel through the system.


    There’s More to Know
    On large-scale professional productions cue sequences must be linked to the timing of
    scene shifts, flying elements, lights, and sound. In these productions some parts of the fly
    system operation is motorized so that a number of flying pieces can move at just the right
    speed and in the right order without requiring a large fly crew. These motor-controlled
    cue sequences are often run by software called Show Control. In addition, large productions
    often use individual power winches to hang props in the air above the wings, which
    leaves the wings free of clutter.


    Mechanical Advantage, 2 to 1


    Mechanical advantage allows for the use of pulleys to share the weight of a lift line
    allowing a single technician to lift more than their own weight.


    While stage scenery is designed to provide a representation or illusion of the desired
    location(s) for the play, it is often as important to hide what you don’t want the audience
    to see as it is to represent what you do want them to take in visually. Rigged
    from the fly system, theatre draperies create a void that surrounds the performance


    These drapes help designers to mask what they don’t want seen. There are specific
    names for each piece of theatrical drape. The main drape or grand drape is often
    richly colored and sits just behind the proscenium arch. This drape traditionally
    opened to reveal the set at the top of a show. It is now common for the set to be
    exposed when the audience enters the theatre, and so you may only occasionally see
    this drape closed, but even when open, it is often visible at the edges of the proscenium.
    Above the main drape is usually a grand valence or grand teaser. This drape
    is also richly colored to match the main drape and helps to block the audience’s
    view of the lights and other equipment hanging above in the fly loft. A series of
    tall but narrow black draperies mask the view into the wing space along both sides
    of the playing area. These vertical drapes are known as legs and tormentors. The
    first set of drapes upstage of the proscenium are termed tormentors and are typically
    flat-faced, black drapes. The vertical drapes upstage of the tormentors are the
    legs, which are often pleated. A flat-faced drape known as a teaser is a short wide
    drape hung in front of the set of tormentors to mask the fly gallery equipment.
    This masking continues upstage with borders hung in front of each set of legs. In
    some theatres, additional masking is hung in the wings running perpendicular to
    the main drape. These are referred to as tab drapes. Theatres may be equipped with
    a blackout drape, a full, stage-width, black drape, or a blackout traveler that can be
    traversed open as needed.

    Drops are another series of soft goods used in scenery. Drops are traditionally large
    pieces of painted or colored canvas or muslin that provide large-scale backgrounds.
    They can be rigged to fly in and out if the theatre is so equipped. Usually, they are
    constructed with ties at the top seam so they can be easily attached to battens. The
    bottom hem may be equipped with a pocket for a pipe or chain that provides weight
    to help the drop hang flat and stay in place. Musical theatre tends to rely on a series
    of painted canvas drops to quickly move the story from one location to another.
    The sky drop, which is mounted upstage of the playing area to serve as background,
    is another common drop. Though now rare, a cyclorama may be used upstage in
    place of a sky drop with its extreme ends curving toward the apron to partially surround
    the playing space. Cut drops have a profiled edge to help layer an image such
    as tree foliage. A portal is a drop with its center section cut away to create a surface
    with a smaller opening than the natural proscenium. A false proscenium is often a
    hard-faced portal that has been constructed to replace or augment the look of a theatre’s
    natural proscenium arch. A show curtain is a drop that may replace a main
    drape for a production and has been created as part of the scenic environment.

    Drops often need special lighting to make them convincing illusions. Space might
    need to be allocated for a decorative ground row, which masks lights placed behind
    it to up-light a drop from the stage floor.
