Luck is a song included in the Halo 3: Original Soundtrack. The song plays only once, during the Halo 3 Cutscene-only level "Arrival"

The song starts with a light melody of wind instruments with choir interspersed in between. The introduction melody comes to a dramatic climax, then turns to a more peaceful strings section. Near the end, wind once again takes the melody, which is replaced by piano at the end.

The song is most likely in reference to the Master Chief's supposed "luck" as mentioned by Cortana in the video.

It runs for 3 minutes and 25.244 seconds (3:25.244).

This song carries the traditional violins heard at the beginning of all three games. This is its shortest form, while Halo 2 Cairo Suite features the longest.
