Ridley's Chamber has a low and sinister melody, playing softly between a four-note pattern that rises in pitch in the song's second half. The result is reminiscent of other contemporary "dungeon themes" from the NES era, such as the castle theme from Super Mario Bros. and the dungeon theme from The Legend of Zelda, which combine low melodies with a short repeating harmonic pattern. Its highly repetitive nature is evocative of the confusing and disorienting atmosphere of a maze, and the annoying frustration of trying to solve it.
Ridley's Chamber is remixed in the Zero Mission remake. Now, the repeating four-note pattern is much softer in relation to the melody, helping to alleviate some of the original's potentially annoying sound. The song has also been significantly extended with more melodic lines. Its instrumentation and arrangement, particularly due to the addition of glissando, are reminiscent of the ghost house theme from Super Mario World. It is designated as 13 in the Sound Test.
