Greatest Journey
From Halopedia, the Halo wiki
Greatest Journey is a song included in the Halo 3: Original Soundtrack. It plays during the level Halo.
The song starts with a slow choir-and-strings melody. The vibrato used by the strings section is very prominent in this section. The motif continues, and at 0:55, changes to a more gloomy and strange tone. This continues until 1:40, when drums start beating. This leads to the start of the Halo 3-version of the Halo Theme from the Halo 3 E3 2007 Trailer. This could be considered the "turning point" of the song. At 4:30, the Halo Theme section ends, and high strings and piano play the last notes.
It runs for 5:57.
Note: The name of the song could refer to the Great Journey.
