174 Hz is the lowest of the nine Solfeggio frequencies, and the one people reach for when they want to feel held. It sits low and warm, more felt than heard, and the tradition treats it as the ground floor of the whole scale.
What 174 Hz means
In the Solfeggio tradition, 174 Hz is the foundation tone: safety, grounding, and physical ease. It's the frequency people put on when the body is tense and the mind will not settle — the sonic equivalent of putting your feet flat on the floor. Because it's the lowest tone, it's often described as giving your other frequencies something to stand on.
The honest part
You'll see 174 Hz sold as a "natural anesthetic." That claim isn't supported by credible research, and no tone is a substitute for medical care. What is real: low, steady, warm sound reliably slows the breath and lowers physical tension. That's not nothing — it's most of what people are actually feeling. Use it as a grounding tool, not a painkiller.
How to use it
- Play it low while you do anything that asks your body to settle: stretching, lying down, slow breathing.
- Pair it with your feet on the floor and a longer exhale than inhale.
- Good as a base layer under a quiet evening or a hard day.

Frequently asked
What is 174 Hz good for?
174 Hz is the lowest Solfeggio tone, traditionally used for grounding, safety and physical ease. People play it when the body feels tense — its real benefit comes from low, steady sound helping you settle, not from any medical effect.
Does 174 Hz relieve pain?
There's no credible evidence that 174 Hz works as a painkiller, despite the "natural anesthetic" claim. It can help you relax, which may make discomfort easier to sit with, but it is not a substitute for medical care.
Is 174 Hz the lowest Solfeggio frequency?
Yes. The nine Solfeggio tones run from 174 Hz up to 963 Hz, so 174 Hz is the base of the scale — which is why it's associated with foundation and grounding.
