174 Hz is the lowest of the extended Solfeggio frequencies. In the Solfeggio tradition it is commonly associated with a feeling of physical grounding — a low, steadying tone that many listeners describe as calming and settling. It is important to be clear from the start: these are perceptions and traditions, not medical facts, and 174 Hz is not a treatment for pain or any condition.
Where the 174 Hz association comes from
The extended Solfeggio set (174, 285 and 963 Hz) was added to the original six tones by sound-healing writers in the late 20th century, building on the numerology popularised by Dr Joseph Puleo and Dr Leonard Horowitz. In that tradition 174 Hz was placed at the foundation of the scale and framed as the “anchor” tone — the one associated with the body itself.
How people listen to 174 Hz
People who listen to 174 Hz often use it for body-scan meditation, wind-down routines and sleep preparation, and many report a sense of relaxation. Whether that comes from the specific frequency or simply from sitting quietly with a low, steady tone is exactly the kind of question research has not settled — so treat it as something to experience for yourself rather than a promised outcome.

Is 174 Hz safe to listen to?
At a comfortable, moderate volume, listening to a 174 Hz tone is generally considered safe for most people, just like any quiet music. Keep the volume low, take breaks, and stop if you feel any discomfort. It is not a medical treatment and should not replace professional care.
What does 174 Hz actually do?
Traditionally 174 Hz is associated with grounding and stress relief, and many listeners report feeling calmer. There is no strong scientific evidence that the specific frequency produces a specific physical effect, so it is best understood as a relaxing listening experience rather than a guaranteed result.
What note is 174 Hz?
174 Hz is almost exactly the musical note F3 (174.61 Hz), only about 6 cents flat — making it the closest match to a standard note of any Solfeggio tone.
How is 174 Hz different from 528 Hz?
174 Hz is a low tone traditionally associated with the body and grounding, while 528 Hz is a higher tone associated with the heart and transformation. Neither has proven medical effects; they simply sit at different points in the Solfeggio tradition.
