This page opens the tone generator already set to 741 Hz — choose a waveform and duration, generate the tone, then play it or download the WAV. In the solfeggio tradition 741 Hz is called the frequency of expression and problem-solving. There is no scientific evidence behind these claims — treat the tone as a relaxation aid and judge by ear.

Pure tones are handy for testing speakers and headphones, tuning instruments by ear, audio experiments and relaxation sessions. Start at a low volume — a sustained pure tone can be harsh when loud.

Need a different pitch? Open the full generator and dial in any frequency from 20 Hz to 20 kHz. Everything runs locally in your browser — nothing is uploaded or stored.
