Suite Autumn

200px|right Suite Autumn is a suite/medley of short music pieces included in the Halo: Original Soundtrack. It runs for 4:24.

It plays during the levels Pillar of Autumn(0:49-1:27), Halo(0:00-0:48), 343 Guilty Spark(3:02-4:24), Two Betrayals, Keyes, and The Maw(1:28-3:01) after the player leaves the bridge and his arrival via Banshee, respectively. The tone is sombre, and somewhat ominous. The tone adds to an atmosphere of uncertainty, with the Pillar of Autumn's sharp turns sometimes you never know whats around the corner. The title of the piece is a play on "Sweet Autumn".
