Halo Theme

The Halo Theme is the staple music of the Halo series.

Halo: Combat Evolved


In its original incarnation, featured frequently in Halo: Combat Evolved, it placed heavy emphasis on deep, powerful drums and fast paced strings. The track is heard most prominently at the start of the level The Silent Cartographer, during the beach landing and during the final Warthog run segment of The Maw. The chant at the beginning of the piece was used for the main menu screen in-game. On the Halo: Original Soundtrack, however, it was the last track, and also included the bonus track Siege of Madrigal at the end.

Halo 2
For Halo 2, the theme was remixed into the MJOLNIR Mix. The basics of the theme remain the same, but it features electric guitar overlays by former Whitesnake guitarist Steve Vai. Halo 2 uses the track in its original form in certain parts, such as at the beginning section of the level Metropolis. The MJOLNIR mix is played at the end of Metropolis as John-117 boards the Scarab, and later during the end credits. It is the first track on the Halo 2 Soundtrack Volume 1.

Halo 3
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 finishes with the ending used at the end of The Maw, as opposed to the reprise of the opening chant used in the original theme and the MJOLNIR Mix. Occasionally, 343 Guilty Spark can be be heard humming it with the IWHBYD skull activated in campaign.

Halo 4
It has been confirmed that the Halo Theme will make a return in Halo 4. It can be heard in the opening scene of the level "Composer", when John-117 and Cortana observed Installation 03.

Other media
The soundtrack for Halo Wars, composed by Stephen Rippy, also uses the Halo Theme at various points, including Spirit of Fire, Quite the Vacation Resort, and We're Burning Sunshine.

The Halo Theme does not appear in Halo 3: ODST. While stated before release that the Theme would not appear in Halo: Reach, several tracks in the soundtrack borrow motifs from it. For example, "Immemorial" from Overture takes three bars from the beginning of the chant, while "Unreconciled" from Tip of the Spear takes the drumbeat and uses both the beginning of the chant and the main melody.

A re-orchestrated version of the theme serves as the theme of Halo: Combat Evolved Anniversary.

The Halo Theme is used in the closing moments of the teaser trailer for Halo 4, implying that the Theme will appear in the game itself.

The initial eight notes of the chant appear after John-117 kills the second Hunter in Part 5 of Halo 4: Forward Unto Dawn.

Halo Legends
A partial remix of the track appears in the Halo Legends Original Soundtrack. This remix plays during Halo Legends episode Origins during the scenes depicting the escalation of the Human-Covenant War.
