Some pieces of the game's music are produced with a much larger real orchestra than anything in the prior two games. For example, the music for the announcement trailer was recorded with a 60-piece orchestra and a 24-piece choir. Halo 3 is the first game in the series to feature custom soundtracks, allowing players to replace in-game music with their own choices.
