Deference for Darkness
From Halopedia, the Halo wiki
Not to be confused with Deference of Darkness.
Deference for Darkness is the fourth track (Disc 1 Track 4) included in Halo 3: ODST Original Soundtrack, and plays in the Halo 3: ODST campaign level Mombasa Streets. It is composed of Rain (0:00-3:07), Trailhead (3:07-4:47), and Guiding Hand (4:47-6:35).
Rain (3:07) begins with four piano chords with high strings playing in the background. A tenor saxophone enters with a three note cue. The piano plays a slow melody while accompanied by high strings. The piano leads with variation of the melody, then strings take over. The low strings and piano play in the background while high strings play a flowing melody dramatically before slowing down. The tenor saxophone returns for another three note cue, following by low strings and piano playing the second theme of the piece: a somber flowing melody which slowly builds up to melancholic climax. The piano then returns to the first slow melody, but accompanied by the tenor saxophone. The pieces ends on the piano's reprise of the first chord in the opening piano solo. The piece plays in the campaign level during the cutscene following Tayari Plaza and continues into the gameplay sequence afterwards. A piano-only version plays in Another Rain (in the track The Light at the End). Elements of the piece, especially the saxophone's three-note cue and the flowing melody in the middle of the piece, would be later incorporated into Hell of a Night (in the later track Special Delivery), Orbital Drop Shock Trooper and Prepare to Drop (in the later track Finale).
Trailhead (1:40) features percussion and digital notes playing a crisp and fast melody. The melody repeats in variations before fading out. The piece plays randomly when roaming in Mombasa Streets. A percussion-only version plays in Clear the Air (from the later track The Office of Naval Intelligence).
Guiding Hand (1:48) contains eerie ambiance with synth notes and digital chimes. It repeats before fading out. The piece plays randomly when roaming in Mombasa Streets.
