Halo Theme

The Halo Theme is the staple music of the Halo series and is instantly recognizable by fans of the games.

In its original incarnation, featured frequently in Halo: Combat Evolved, it placed heavy emphasis on deep, powerful drums and fast paced strings. The song is heard most prominently at the start of Silent Cartographer, during the beach landing and during the end credits. The chant at the beginning of the piece was used for the main menu screen in-game. It is also a deep religious theme referring to the Forerunners, as the Monitor will hum it in Halo 3 with the IWHBYD skull on. It is as well as being the first true music heard by the player. On the Halo: Original Soundtrack, however, it was the last track, and also included the bonus track Siege of Madrigal at the end.

Future Use
For Halo 2, the song was remixed into the MJOLNIR Mix. The basics of the song remained the same, but it featured impressive electric guitar overlays by former Whitesnake guitarist Steve Vai. Halo 2 continued to use the song in its original form in certain parts, such as at the beginning of the level Metropolis. The MJOLNIR mix was played at the end of Metropolis, as the Master Chief boards the Scarab, and later during the end credits, is the first track on the Halo 2 Soundtrack Volume 1.

The theme was again revised for Halo 3, this time recorded with a live orchestra instead of synthesized strings. The version used in Halo 3 finished with the ending used at the end of The Maw (Level), as opposed to the reprise of the opening chant that the original theme and the MJOLNIR mix had used.

The soundtrack for Halo Wars, composed by Stephen Rippy, also uses the Halo Theme at various points, most prominently during Spirit of Fire.

Trivia
