Area 4 (theme)

Area 4 is a theme from Metroid: Samus Returns. It was composed by Daisuke Matsuoka.

Description
Area 4, as its name implies, can be heard in the first half of Area 4, where Samus Aran acquires the Wave Beam and hunts down a single Gamma Metroid. It is a very atmospheric track with a few minimalist melodic patterns repeated throughout. Area 4 can be heard here:

Area 4 may be based upon the ambient track originally played in Phase 5 and Phase 7 in Metroid II: Return of Samus. This theme, originally composed by Ryoji Yoshitomi, has some similar note patterns to Area 4. Since Phase 5 corresponds directly to the first half of Area 4, this may have been a deliberate reference by Daisuke Matsuoka, although this is not confirmed. This ambient theme can be heard here:

Trivia

 * In the internal files, this track is called Area 6. However, this theme does not play at all in Area 6.
