Editing Music of Halo 2

==Overview==

===Development===

One of the first tracks composed for Halo 2 was [[The Last Spartan]], which was the backing track for the [[2002]] [[Halo 2 announcement trailer]]. The Last Spartan is representative of many compositions in Halo 2, where composers [[Martin O'Donnell]] and [[Michael Salvatori]] introduced new motifs, whilst reusing and incorporating musical themes from [[Halo: Combat Evolved]]. In the case of The Last Spartan, the track begins with its own motif before ending with [[Prologue (music)#Cloistered Expectancy|Cloistered Expectancy]], the Halo 2 rendition of the Gregorian chant. Other examples include [[Impend]], which opens with the ending of [[Brothers in Arms]], and [[Heretic, Hero]], which opens with its own melody before incorporating the main melody of [[A Walk in the Woods]] in its second half. Other than the Gregorian chant, only two tracks in Halo 2 were outright arrangements of tracks from Halo: Combat Evolved, including [[Remembrance]] (arrangement of [[The Maw (music)|The Maw]]) and [[Prologue (music)#Cold Blue Light|Cold Blue Light]] (arrangement of the fourth section of [[Opening Suite]]).  

The Last Spartan also demonstrated the reuse of motifs introduced in Halo 2, with its motif incorporated into two other tracks that were composed in the early stages of the development. [[Mombasa Suite#Skyline|Skyline]], likely written early due to its inclusion in the [[Halo 2 E3 demo]], incorporated the main motif of The Last Spartan. Similarly, [[Earth City]], another track composed for the demo and later featured prominently at multiple points in the game, incorporated the main motif of The Last Spartan as well as the Gregorian chant from the Halo Theme.
