About the 396 Hz tone
396 Hz is the lowest of the classic six Solfeggio tones and one of the most frequently used in meditation and ambient playlists. As a mid-range pitch it reproduces cleanly on almost any speaker or headphones.
This page generates 396 Hz as a pure sine tone. We describe the frequency and its place in the series but make no claims about it — play it however you like.
On the keyboard, 396 Hz sits just below G4 — the G above middle C — a touch flat of it; the generator shows the exact note and how many cents away it is. To build a fuller drone, open a second tone at its octave (792 Hz) or layer it under brighter neighbours like 528 or 639 Hz, where its low-mid pitch works well as a steady bass note. Switching the waveform from sine to triangle or square adds upper harmonics if the pure tone feels too plain.
