Key Takeaways
- The basic concert lighting rig has three layers: key light (illuminates the performer), effects (creates visual energy and atmosphere), and wash (provides colour and ambience to the full stage)
- Moving heads are the most versatile fixture in a concert rig — they provide key light, wash, and beam effects from the same instrument
- Follow spots (manually operated spotlights that track the performer's movement) are essential for large concerts where performer movement range exceeds what automated fixtures can cover
- Hazer density must be calibrated for the venue — too little and beams are invisible; too much and visibility is impaired
- Concert lighting programming (pre-programming cue states before the show) takes 6–10 hours for a medium-complexity rig — this time must be in the load-in schedule
The three-layer rig
Key light: The lighting that makes the performer visible and photographable. Moving head profiles (hard-edged fixtures with sharp beam control) provide the cleanest key light. Position: overhead front (at 45° to the performer's face from both above and the side). Colour temperature: 3,000–3,200K for warm-skin-tone rendering; cooler temperatures for electronic and DJ formats. Effects: Moving heads in beam mode (narrow, intense beams that create geometric patterns and movement), strobes (impact at specific musical moments), and laser systems for high-energy concerts. Effects are what make a concert look like a produced spectacle rather than a well-lit stage. Wash: LED pars (colour-changing wash fixtures) covering the full stage surface with controllable colour. Wash provides the stage's ambient colour palette — the backdrop against which the key light and effects are layered.
The programming workflow
Concert lighting is pre-programmed to the artist's set list before show day. The lighting programmer (often a separate role from the LD for larger concerts) works through the show cue-by-cue, building lighting states for each song's verse, chorus, bridge, and climax. A 90-minute concert set with 12 songs and 4 states per song requires programming 48 cue positions — plus transitions, intro states, and emergency states. At a typical programming rate of 4–6 cues per hour, this is 8–12 hours of programming. For shows where the artist's set list changes, the programmer must be available on show day to update cues.
