Son et lumière (show)
Son et lumière French pronunciation: [sɔn ɛ lymjɛʁ] (French, lit. "sound and light"), or a sound and light show, is a form of nighttime entertainment that is usually presented in an outdoor venue of historic significance.
Special lighting effects are projected onto the façade of a building or ruin and synchronized with recorded or live narration and music to dramatize the history of the place. The invention of the concept is credited to Paul Robert-Houdin, who was the curator of the Château de Chambord in France, which hosted the world's first son et lumière in 1952. Another was established in the early 1960s at the site of the Great Pyramid of Giza in Egypt.
This nighttime medium naturally lends itself to ecclesiastical buildings, stately homes and ruins, and has rapidly become very popular in France where about 50 annual productions take place, principally in the Loire Valley, at the Palace of Versailles and at Les Invalides in Paris.
The format usually involves no active participation by actors but a recorded narrative of the history of the building concerned by one or a cast of voices. To this is added music or sound effects as appropriate, all of which is synchronised to lighting and/or projection effects which provide the visual dimension. Pyrotechnic effects are occasionally included for added spectacle.
A relatively recent variation is that, rather than the music and narration coming through a concert-like sound system, they may use headsets, such as in Philadelphia, Pennsylvania's "Lights of Liberty". This allows an audience to move through a historic district as the show proceeds.
Performances around the world 
In France, son et lumière shows are performed in and around France's historical châteaux.
In neighboring Luxembourg, a son et lumière event took place in 2007 at the Chateau de Septfontaines.
Further afield, the first African production was at the Pyramids of Giza at Cairo, Egypt, in 1961, while the first in Asia was the Red Fort in Delhi, India in 1965 by the India Tourism Development Corporation.
In Britain, where the majority of such productions have been staged at churches, cathedrals and abbeys, indoor presentations are frequently preferred, particularly as architectural gems might otherwise not be shown to best advantage. The first British production was at Greenwich Palace in south London in 1957. In England in particular, where son et lumière is as well received as it is in France, many of the nations's principal historic houses and church buildings have enjoyed such a production. Of particular interest have been the ones at Canterbury Cathedral (produced as part of the European "Cathedrales en Lumière" events), Rochester Castle, St Augustine's Abbey, St. George's Hall, Liverpool, Tewkesbury Abbey, St Paul's Cathedral, Hampton Court Palace, and at Chartwell, the country home of Winston Churchill. Part of the London 2012 Olympic bid involved the use of son et lumière inspired light projections of athletes upon various London buildings.
In India, popular shows are at Red Fort, Purana Qila, Delhi, and Golconda Fort. In Peru, a son et lumière show opened in Park of the Reserve, Lima in 2007, called "Circuito Mágico del Agua" (magic water circuit) which has a Guinness record as the world's largest water source exposed in a public park.
Composers who have produced son et lumière shows include Jacqueline Nova and Halim El-Dabh. French electronic music composer Jean Michel Jarre has incorporated son et lumière productions into his live concerts, which often take place outdoors at historical sites, sometimes with more than one million spectators.
