- This article is about the theme known as "Area 1" in the Sound Test. For the themes internally referred to as Area 1, see Area1 Add1 and Matad Area01 Damage.
Area 1, as its name implies, can be heard throughout Area 1. It also temporarily plays in the second half of Area 7 while Samus Aran is hunting down the remaining Omega Metroids, after she passes through a Gryncore-blocked door. Once the Omega Metroids are all exterminated, then Chozo Laboratory will permanently replace Area 1.
Area 1 has two sections. The first consists of a flute-like instrument playing a series of rising notes, alternating between playing it slowly and quickly, while quiet high-pitched synths in the background mimic this pattern at a much faster pace. The second section features dark and mysterious vocals that resemble throat singing. Area 1 can be heard here: 
Area 1 is based upon the beginning of the ambient track originally played in Phase 2 in Metroid II: Return of Samus. This theme, originally composed by Ryoji Yoshitomi, likewise opens with a rising pattern of high-pitched notes first played slowly and then repeated at a faster pace. The high-pitched synths in the Area 1 theme in particular sound remarkably similar to the original chiptune. While Daisuke Matsuoka fully remixed this theme as one of the tracks played in Area 3, this Area 1 theme was his way of retaining the track's original context. The original ambient theme can be heard here:
