The Map Room: Dawn

The Map Room: Dawn was played in Raiders of the Lost Ark during the Map Room scene where Indiana Jones places the Staff of Ra down to find the location of the Ark of the Covenant. It is a beautiful rendition of the Ark motif, and may even be considered the most complete representaion of the Ark Theme in the movie. The music starts slow and mysterious, with a hint of foreboding, and gradually builds to a swirling apogee accompanied by high vocals as Indy revels at the revelation of the Ark's location by the staff. The theme suggests the great power and holiness of the object by the grandness and raised sound of the music.
This piece is mirrored later in the movie as the Ark is opened, in the track titled The Miracle of the Ark, only it twists to become much more dark, sinister and vengeful.
A section of the piece also appears at Hangar 51 closing Raiders and again in the same building near the beginning of Indiana Jones and the Kingdom of the Crystal Skull.
