741 Hz
Free healing-frequency, solfeggio & Om sound generator
The "Sol" solfeggio tone — bright and clear. Play it pure, or soften it with the drone layer.
Start at a low volume and turn up slowly. Pure tones can sound louder than music at the same setting, especially higher frequencies.

741 Hz carries the syllable "Sol", from "Solve polluti labii reatum" ("loosen the guilt of our stained lips") in the hymn Ut queant laxis. Solfeggio writers read "solve" and "polluted lips" as a theme of cleansing and self-expression, which is where the modern associations come from. The number itself was assigned in the late 20th century; its digits reduce to 3 (7 + 4 + 1 = 12).
You will see 741 Hz described as the frequency of "expression and solutions", "awakening intuition", "detox" or "cleansing cells", and chakra charts assign it to the throat. (Different sites also swap the descriptions of 741 and 852 Hz, a sign of how loosely the meanings are defined.) None of these effects has been demonstrated; a sound does not detoxify the body.
Practically, the hymn's theme of speech makes 741 Hz a nice choice before something voice-related — warming up for chanting, singing practice or a talk — purely as a focusing ritual.
741 Hz is within about 2 cents of F#5, which is 739.99 Hz in standard tuning — effectively the same note. So unlike several other solfeggio tones, 741 Hz blends cleanly with instruments, singing bowls or a voice pitched to F#.
Nobody has shown that a particular frequency heals the body, repairs DNA or treats a medical condition. The specific benefits attached to each solfeggio number are claims from the books and videos that popularised them, not findings from controlled research. What is well supported is more modest: calm, steady, predictable sound that you like can help you relax, mask distracting noise and give your attention somewhere to rest. Any of these tones can do that — and so can plenty of others.
Use it for: relaxation, meditation, a calm background while you read or rest, sound exploration, or simply because you like it. Don't use it as: a treatment for any medical or mental-health condition. For a deeper look at the whole set, see the solfeggio frequency list.
It is promoted for self-expression, problem-solving and "cleansing", but there is no evidence for these effects. It is a clear, bright tone some people like for focus or before voice practice.
No. There is no scientific evidence that any sound frequency detoxifies the body or cleans cells.
F#5. In standard tuning F#5 is 739.99 Hz, so 741 Hz is only about 2 cents sharp — practically identical.
Human hearing is more sensitive in the upper-mid range, so higher tones seem louder at the same level. Lower the volume for higher frequencies.
