Where 285 Hz sits in the Solfeggio set
285 Hz is the second of the three "foundation" tones (174, 285, 396 Hz) that ground the extended Solfeggio sequence before the well-known core set begins. Tradition assigns it themes of repair and renewal - practitioners describe using it when recovering from illness, injury, or exhaustion, typically as a quiet drone during rest or body-focused meditation.
In musical terms, 285 Hz sits between C#4 (277.18 Hz) and D4 (293.66 Hz) - about 48 cents above C#4, almost exactly a quarter tone between the two. Like the other Solfeggio tones, it does not correspond to a standard-tuning note, which gives it a slightly unplaceable quality when heard next to conventional music.
Honest expectations, practical use
There is no peer-reviewed evidence that 285 Hz - or any audio frequency at listening volume - accelerates tissue healing; the numerological origin of the Solfeggio set dates to the 1990s. What listening practices genuinely support is rest: slow breathing alongside a steady quiet tone reliably reduces arousal, and rest is a real contributor to recovery.
Used that way, 285 Hz is a pleasant low-mid drone - warmer than 396 Hz, more present on small speakers than 174 Hz. Sine is the purest; triangle adds a soft, organ-like body that some listeners prefer for longer sessions. Download the WAV to loop it in any player.
