Marc-Antoine Charpentier was a French Baroque composer during the reign of Louis XIV. One of his most famous works is the main theme from the prelude of his Te Deum, Marche en rondeau. This theme is still used today as a fanfare during television broadcasts of the Eurovision Network and the European Broadcasting Union.
