Overview
quiet room is a Vocaloid-originated track by Japanese music producer 有機酸 (Yuukisan), first released in 2017 on the album troy with vocals by Hatsune Miku. For its inclusion in maimai DX, Yuukisan recorded a self-cover version, a relatively uncommon treatment for Vocaloid songs in the rhythm-game context at the time, giving the track a more personal, intimate character than its original iteration.
Musically, quiet room moves at a deliberate 93 BPM with sparse instrumentation and a subdued, melancholic atmosphere that sets it apart from the high-energy Vocaloid tracks typical of the niconico & VOCALOID genre. The accompanying music video was created by 東洋医学 (Tōyō Igaku), whose visuals reinforce the song's muted, introspective mood.
In the maimai context, quiet room is perhaps best known for its MASTER chart, designed by はっぴー (Happy). はっぴー has publicly stated that quiet room is their personal favorite song from the original maimai でらっくす, and its MASTER chart their favorite chart from that same release, a rare candid endorsement from a seasoned notes designer. The MASTER chart's relatively sparse note density for a level-12 difficulty and its emphasis on Slide and Touch patterns reflect the song's spacious, breathing quality. The EXPERT chart, designed by シチミヘルツ (Shichimi hertz), offers a complementary but denser intermediate arrangement. Across all difficulties, quiet room was available from the launch of the DX series and required no special unlock conditions.
