A spike is a precise marking, typically made with tape, on the stage floor, a piece of scenery, or a prop, indicating the exact position for an object, a set piece, or an actor's blocking. These marks serve as crucial visual guides for the stage crew and performers, ensuring accuracy, consistency, and efficiency throughout rehearsals and performances.
Purpose
The primary purposes of spikes in stagecraft include:
- Precision and Consistency: To ensure that all props, furniture, and set pieces are placed in their identical, designated locations for every rehearsal and performance. This is essential for maintaining the director's artistic vision, preserving sightlines, and facilitating smooth transitions.
- Actor Blocking: To mark specific positions where actors need to stand, sit, or move, aiding them in consistently hitting their marks and recreating stage pictures.
- Efficiency: To expedite scene changes by providing clear visual cues for where items belong, thereby reducing guesswork, potential errors, and delays during live performances.
- Safety: To prevent accidents by ensuring that objects are not placed where they might obstruct entrances/exits, create tripping hazards, or interfere with technical elements.
- Technical Cues: While less common for stage floor marks, spikes can occasionally indicate focus points for lighting, precise placement for audio equipment, or other technical elements requiring specific alignment.
Application and Materials
Spikes are generally applied by the stage management team, often during technical rehearsals or prior to performances, once final blocking and set placements have been determined.
-
Materials:
- Gaffer Tape: The most common material due to its strong adhesive, durability, and ability to be removed without leaving residue. It is available in various colors, allowing for differentiation (e.g., different colors for different acts, characters, or types of items).
- Glow Tape: Phosphorescent tape used for marking items or positions that need to be visible in low light or complete blackout conditions.
- Paint Pens/Markers: Sometimes used on less visible areas of the stage or directly on props for more permanent or subtle marks.
- Chalk: Occasionally employed for temporary marks during early rehearsals or initial layouts.
-
Placement:
- Stage Floor: The most frequent location for spiking, marking the "footprint" or perimeter of furniture, the center points of props, or the standing positions for actors.
- Scenery/Props: Spikes can also be placed on scenery or props themselves to indicate where other items should be placed in relation to them, or to mark specific orientations.
- Fly Lines: In some rigging systems, lines on the fly system may be "spiked" with tape to indicate specific trim heights for flown scenery.
Types of Spikes
- Prop Spikes: Marks indicating the exact placement of furniture, hand props, and set dressing (e.g., the corners of a table, the base of a lamp, the position of a rug).
- Actor Spikes (Blocking Spikes): Small marks, often an 'X', 'T', or a line, indicating where an actor should stand or hit a particular position during a scene.
- Reference Spikes: Marks used internally by the crew for alignment purposes, such as aligning two pieces of scenery during a scene change or indicating where a curtain should stop.
Importance
The meticulous and accurate use of spiking is a fundamental aspect of professional stage management. It underpins the smooth, consistent, and safe operation of a theatrical production, enabling complex stage movements and rapid scene changes to occur seamlessly, thereby contributing significantly to the overall quality and success of a performance.
