Ice Chapel

Ice Chapel (as named in Metroid Prime & Fusion Original Soundtracks) is a theme from Metroid Prime. It was composed by Kenji Yamamoto.

Description
Ice Chapel plays exclusively in the Chozo Ice Temple in the Phendrana Drifts, where Samus Aran acquires the Wave Beam and fights an adult Sheegoth for the first time.

Ice Chapel is orchestrated similarly to other Chozo temple themes in the game, such as Chozo Shrine, with an ethereal choir melody and ambient synths. It also uses high-pitched instruments heard in other music tracks associated with Phendrana Drifts to evoke the frozen atmosphere. It can be heard here:

While the Ice Chapel theme has never been featured in another game in its entirety, the opening notes of its melody are adapted into Matad Jinchozo, a jingle that plays when a Chozo Seal is unlocked in Metroid: Samus Returns.
