Lament for Pvt. Jenkins

Lament for Pvt. Jenkins is a piece included in the Halo: Original Soundtrack.

This piece is played during the cutscene where Master Chief watches the video feed from Jenkins' helmet. The theme is also played on the level The Silent Cartographer, when Dropship Bravo 22 gives a Mayday call.

Overview
The piece is a tense, moody ambient song by string orchestra. The piece opens with a dark, powerful drumbeat, followed by an apprehensive minor chord. Every seven seconds, the drum sounds again, punctuating a change in the chord. The song becomes increasingly disjointed towards the end, featuring the scrambled high notes typical of the Flood, and slowly fades out, leaving a dark air to the scene.

It is also featured on the ad for Halo 3, Arms Race, right after a Marine is shot by a Brute Spiker.

Nomenclature
The name is clearly derived from the Chief witnessing the horrible fates of Jenkins, Bisenti, Mendoza and the rest of Johnson's squad.
