Gravemind (music)

200px|right Gravemind is a musical piece included in the second disk of the Halo 3 Original Soundtrack. In the Halo 3 campaign, it plays during the levels the Covenant and Floodgate and is five minutes and 22.037 seconds long (5:22.037).

The song is relatively quite until around 1:01, when the music's tempo rises with intense, electrically-generated sounds. These sounds are a "remix" of the Halo: Original Soundtrack piece Devils... Monsters..., apart from the Gravemind speaking in the background, which may result in the name of this track. This is the classic Flood music, meant to involve the player in the game with its fear-instilling beat and sounds. At approximately 1:52, the excerpt of Devils... Monsters... dies down and a chorus begins a slow melody. In the Floodgate gameplay, this would be when the Shadow of Intent arrives at the Battle of Voi. After this (at around 2:50), another chorus will begin a second Flood musical, except this part was made solely for the Halo 3 Original Soundtrack. This beat is generally based on a group of singers, and has an eerie feeling to it. At about 3:12, a short violin solo plays numerous high-pitched notes extremely fast. Finally, the Halo 3 theme plays until the end, with the exception of a drum-solo in the middle of it.

Trivia
The background message often refers to a line deciphered as "Side by side we march as one. Humans and Elites will fall."
