About the 741 Hz tone
741 Hz sits high enough to cut through a mix but well within the range every set of headphones and speakers reproduces easily.
As with the other Solfeggio tones, this page generates a clean 741 Hz sine wave and makes no claims about it — it's simply the frequency, ready to play.
On the keyboard, 741 Hz is closest to F#5 (the F-sharp roughly an octave and a half above middle C), a little below it — the exact cents are shown on the generator. It’s the fifth of the six traditional tones, above 639 Hz and below 852 Hz, and its clear, penetrating character makes it easy to pick out even at low volume. A pure sine keeps it smooth; triangle or square make it noticeably brighter and thinner.
