"Duh-duh-duh-daaaaaah! Duh-duh-duh-daaaaah! It would be a real toe tapper... if I had some. You must listen to Marty O'Donnell, he's quite the genius! He da man!"
Tim Dadabo jokingly acting as 343 Guilty Spark, commenting on the Halo Theme and its composition.[1]
The chant from beginning of the Halo Theme.

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

It is characterized by its opening Gregorian chant, a tribal percussion section, and a low strings section. The low strings section featured a series of triplet rhythms, in which each triplet was followed by the melody leaping upwards by an octave, a ninth, a tenth, and finally an eleventh, before restarting at an octave. The complete theme features high strings playing a high-tempo melody which repeats in variations.

CompositionEdit

The song is set in the key of E Dorian, with two sharps: F and C. The first part of the song is a choir chant which is repeated at the end, and this is set to a beat of 4-4, with the middle section featuring string instruments and percussion; this is set to a beat of 12-8 and is significantly faster than the choir chant. As for the tempo, the starting choir is set to 95 bpm (beats per minute), while the middle section speeds up to 120, before the ending choir chant which settles back to 95.

HistoryEdit

Martin O'Donnell and Michael Salvatori composed the Halo Theme over the course of three days in July of 1999. O'Donnell was asked by Joseph Staten on a Thursday to compose a soundtrack for the then-upcoming Halo MacWorld premiere demo on the following Tuesday. However, the music would need to be first recorded and shown internally within Bungie on Monday — the same day Bungie representatives would board the flight to New York for the presentation on the following day. [2]

Staten told O'Donnell that the theme needed to evoke the game's "ancient, epic and mysterious" atmosphere. To best convey this impression, O'Donnell drew inspiration from his studies on Middle Ages music and decided to incorporate Gregorian chant into the theme, which has since become a staple of the Halo series in its various forms.[3] He was also inspired by the first verse of The Beatles' song "Yesterday", which inspired the four-phrase structure of the Gregorian chant.[4][5] O'Donnell has stated that he laid down the core melody of the theme in about half an hour during the drive to the studio at Salvatori’s house.[2][3]

Recording one day prior to the MacWorld presentation, the theme was recorded with an orchestra composed of six string instruments: four violins and two cellos. O'Donnell and Salvatori sung the Gregorian chant with three jingle singers, who had previously collaborated with the duo on a number of commercials. O'Donnell and Salvatori applied reverb to the strings and choir recordings, while the cello recordings were overdubbed, thus creating the impression of a large orchestra when the recordings were added on top of the MIDI recording. O'Donnell requested one of the jingle players to sing the Qawwali-like solo during the string melody, but upon hearing O'Donnell's example, it was decided O'Donnell would sing the solo instead.[6][5]

After the MacWorld presentation, O'Donnell adapted different aspects of Halo Theme into various pieces of music in Halo: Combat Evolved and its sequels. O’Donnell cited an anecdote from his teacher, film composer David Raksin: according to Raksin, when he expressed concerns over the repeated use of the main theme of Laura in its film score, Raksin was told by his mentor Alfred Newman that good themes should be used repeatedly, while bad themes would have never been used in the first place.[5] O’Donnell and Salvatori followed this philosophy when composing other Halo music - a tradition carried by future composers in the franchise. Called “emotional equity” by O’Donnell, a sense of familiarity would be felt by players when themes are being repurposed, remixed, and reused throughout the trilogy.[7]

An arrangement of the theme, titled Installation 04, serves as the theme of Halo: Combat Evolved Anniversary.

Halo 2Edit

Main article: Halo Theme MJOLNIR Mix

The original piece from Halo: Original Soundtrack was remixed into the MJOLNIR Mix, the first track on the Halo 2: Original Soundtrack, Volume 1. The main theme remains unchanged, 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.

Halo 2 featured Cloistered Expectancy (from the track Prologue), which was the Halo 2 rendition of the Gregorian chant from the Halo Theme.

Two variants of the Halo Theme are featured in the Halo 2 Anniversary Original Soundtrack. The Halo Theme Gungnir Mix is a remixed version of the MJOLNIR Mix from Halo 2, and the Halo Theme Scorpion Mix is a percussion heavy version of the main theme.

Halo 3Edit

Main article: One Final Effort

The theme was again revised for Halo 3, arranged into the track One Final Effort, this time recorded with a live orchestra instead of synthesized strings with the grand piano as its main instrument. 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 heard humming it with the IWHBYD skull activated in campaign.

Halo 4Edit

Main article: Sacrifice (music)

The Halo Theme was reprised as the song Sacrifice. The chant portion of the theme, now referred in the Halo 4 credits as "Halo Cantorum", is heard when Installation 03 is revealed in the level Composer. The main notes of the Halo Theme play in the theme 117 when John neutralizes the external shield generators on Mantle's Approach.

Notes that ambiguously sound similar to the main chorus play subtly when Dr. Halsey tells her interrogator not to underestimate the Spartans.

Halo 5: GuardiansEdit

Main article: The Trials

The Halo Theme returns in Halo 5: Guardians, rearranged as the The Trials with more focus on electronic digital instrumentation. It's also featured as part of the soundtrack in Halo Canticles. It was recorded at Abbey Road[8]

The Gregorian chant can also be heard faintly in the All Hail and The Cost advertisements.

Halo InfiniteEdit

Main article: The Road (music)

The Halo theme returned in the sixth mainline game as The Road. It was first played during the Discover Hope trailer at E3 2019.

Part of the theme plays during the song Set a Fire in Your Heart.

Other mediaEdit

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,[9] 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.

The initial eight notes of the chant appear in the track Axios, which can be heard after John-117 kills the second Mgalekgolo in the climax of Halo 4: Forward Unto Dawn.

Although the Gregorian chant portion of the Halo Theme is used as a major motif in Halo: Nightfall trailer, the original music piece does not contain the Halo Theme.[10]

The initial eight notes of the chant appear in episodes three and six of Hunt the Truth Season 2.

TriviaEdit

  • The country of Palestine aired government-sponsored music videos, and plays, one of which, according to a source, used the Halo Theme music without Bungie's sanction.[11]
  • The opening Gregorian chant consists of a series of 28 (seven times four) notes. Additionally, the second and fourth 'phrases' of the chant each consist of seven notes.
