Tribute (music)
From Halopedia, the Halo wiki
Tribute was a song included in the Halo 3: Original Soundtrack. It plays during the ending cutscene of Halo 3.
It begins with a drum and strings melody similar to the theme from the ending cutscene of the Halo 2 level Cairo Station. Strings then take over with a slow and mournful melody. Higher strings and choir then join in for a second repetition. The melody continues to swell until the end, when it quickly fades.
Note: The song incorporates several elements from both the High Charity Suite and the Cairo Suite.
It runs for 2:52.
