'''Alien Corridors''' is the fifteenth track in ''[[Halo: Original Soundtrack]]''.

==Overview==
The piece is dominated by a series of odd, atonal chimes, similar to the noises given off by [[Covenant]] holo-panels in the accompanying level, ''[[The Truth and Reconciliation]]''. 

The piece starts off with the "alien chimes" alone, but at 00:09, an extremely high synth note begins to assert itself, giving shape and pattern to the chimes. Starting at 00:19, a series of drums start up, giving the piece a driving, yet irregular, beat. At 00:31, a crash of cymbals leads the piece into its main section, allowing the drumbeats to push the piece into a slightly frenetic pace as the high-pitched synth fades out.

At 00:40, an even higher-pitched synth note takes over where the last one left off; the chimes shift their pattern and become somewhat more minor. At 00:49, another cymbal note removes the synth and sets the piece pace forward again as the chimes sound over the pulsing drums. At 00:56, the drums mostly drop out, revealing a midrange synth note underlying the piece; shortly thereafter, the high synth returns to give the beatless piece a sense of shape.

The piece continues without drums; at 01:17, the synth is joined by high strings, which slowly cycle through chords that drown out the chimes. At 01:29 the chimes become briefly audible again as the high strings fade out to make way for lower strings that continue the chords. The piece gradually fades out with the mid-range strings alone.

==Appearances==
The track plays in the ''[[Halo: Combat Evolved]]'' campaign level ''[[The Truth and Reconciliation]]'', when [[John-117]] enters the cargo bay of the [[Truth and Reconciliation|eponymous ship]].

==Arrangements==
The piece was arranged into ''[[Xenoarchaeology (music)|Xenoarchaeology]]'' in ''[[Halo: Combat Evolved Anniversary: Original Soundtrack]]''.

==Production notes==
The name of the piece alludes to the many narrow corridors onboard the ''Truth and Reconciliation''.
