Halo CE Soundtrack

On the Halo CE soundtrack, the Halo theme has a little piano solo at the end, yet I never heard it in the game anywhere. Does anyone know about this?

Siege of Madrigal. It’s from the game series Myth that Bungie made prior to Halo, and appears as an easter egg in all Bungie Halo games when you stand in a specific obscure location.

Oddly enough it was remade in Halo 2 Anniversary but I don’t recall it ever appearing in a campaign map, just Ivory Tower.
