O'Donnell's first piece of music, "Halo", which would become "the signature theme for ''Halo''", was written and recorded in three days.<ref name=ancient/> O'Donnell convinced [[Alex Seropian]] to allow him to produce an original piece of music for the game's 1999 Macworld Conference & Expo demonstration. He drew inspiration for the theme from [[The Beatles]]' "[[Yesterday (song)|Yesterday]]".<ref>{{cite web|author=Staff|date=March 24, 2016|url=http://www.ign.com/videos/2016/03/24/ign-unfiltered-interview-halo-and-destiny-composer-marty-odonnell|title=IGN Unfiltered Interview: Halo and Destiny Composer Marty O'Donnell |workwebsite=[[IGN]]|time=30'00"—35'00"|access-date=March 25, 2016}}</ref> O'Donnell recruited Salvatori and three other colleagues with whom he had recorded jingles with—Robertjingles—Robert Bowker, Jeffrey Morrow, and Rob Trow—to produce the "chanting monks" that open the piece. Originally, he had intended the [[Qawwali]] accents to be sung by one of the professionals, but after singing an example of what he wanted, the others suggested using O'Donnell's own rendition instead.<ref name=ancient/> The theme premiered at the [[Macworld Conference & Expo#1999|1999 Macworld Conference & Expo]].<ref name=ancient/>

The remaining themes were written, recorded, and produced throughout 2001.<ref name=ancient/> The music was written with a variety of equipment, including, "keyboards, synths, and samplers as well as digital recording equipment were controlled by computers".<ref name=ancient/> In addition, [[MIDI]] devices such as the Roland XV-5080 and [[E-mu Proteus|EM-U Proteus 2000]] were most prominently used to create the game's soundtrack. Live instrumentations, fromby members of the [[Chicago Symphony]] and Chicago Lyric Opera Orchestra, were added where needed.<ref name=ancient/><ref name=TotalAudio>{{cite web|first1=Martin|last1=O'Donnell|author-link1=Martin O'Donnell|last2=Wu|first2=Louis|year=1999|url=http://nikon.bungie.org/music.html|title=TotalAudio Questions and Answers|workwebsite=[[Halo.Bungie.Org]]|access-date=April 13, 2008}}</ref> The soundtrack features a wide range of sounds, O'Donnell described it as, "[[Gregorian chant]], string orchestra, percussion and just a bit of a 'Qawwali voice'".<ref name=ancient/> Working closely with level designers, O'Donnell divided the music "into chunks". Based on these "chunks", "[''Halo''<nowiki>'</nowiki>s]which audiocould enginebe couldplayed playback dynamically by [the music]audio backengine dynamically baseddepending on the player's actions".<ref name=ancient/> For the soundtrack release, O'Donnell rearranged the music featured in the game in order to make listening to the soundtrack "more enjoyable".<ref name=album/>
Bungie had previously released soundtracks for their games due to fan request, but Microsoft was hesitant to commit to producing a soundtrack for ''Halo''; at the time most video games did not get a commercial soundtrack release. The publisher finally relented after pressure from O'Donnell and the outside solicitation of musician [[Nile Rodgers]].<ref>{{cite web|author=Reese, Emily|date=September 6, 2011|url=http://minnesota.publicradio.org/display/web/2011/09/06/top-score-martin-odonnell-halo-s2e1/|title=Top Score Launches Season 2 with Halo Composer Martin O'Donnell|publisherwebsite=Minnesota Public Radio|access-date=September 7, 2011}}</ref>

==Reception==
Reception of the soundtrack was generally positive from critics.
