This now instantly recognizable music was originally written for the court of Louis XV, King of France. The stirring piece by composer Jean-Joseph Mouret (1682-1738), is the first movement of Mouret's "First Suite in D," from his second book of Fanfares for Trumpets, Kettledrums, Violins and Oboes (published in Paris, ca. 1729). It is also known as Mouret's "Rondeau" and as the "Theme from Masterpiece Theatre."
