963 Hz solfeggio frequency: the highest crystalline tone of the nine, for awareness and quiet mornings, shown with its waveform

963 Hz is the highest of the nine solfeggio tones, traditionally paired with awareness and a sense of oneness. It is a thin, bright, almost crystalline tone near B5, and it is the frequency behind the most watched Mindael videos. Used softly over a low drone, it suits quiet mornings and the end of a meditation.

What 963 Hz is

963 Hz is the ninth and highest solfeggio tone, one of the three added to extend the original six. As a pitch it sits near B5: thin, bright and close to crystalline. It is also, by a wide margin, the frequency people ask us about most, because it features in our most watched videos. In Mindael it is generated at exactly 963 Hz.

What it is used for

The tradition pairs 963 Hz with awareness and a sense of oneness, the top of the ladder. In practice it is a tone for the lightest moments of a routine: the last few minutes of a meditation, a quiet morning before the day starts, a breath-based practice where you want the room to feel open rather than warm. It is the opposite of a sleep tone, and we do not suggest it for relaxation on its own.

There is no research on 963 Hz specifically; the tone and tuning studies so far concern 528 Hz and 432 Hz, described in the guide below.

How to listen

Fainter than anything else in the mix. A 174 Hz drone or crystal bowls underneath at three or four times its level, and 963 Hz set to where you can just hear it, then one step lower. An alpha 8 Hz beat with earbuds suits a calm, awake morning. Ten to twenty minutes is plenty.

The highest tone, kept where it belongs.

963 Hz only works when it is faint and sitting on something low. Mindael generates it at exactly 963 Hz and lets you pin it over a 174 Hz drone or crystal bowls with the levels saved, so it never gets sharp. Download it and try it at the end of tomorrow morning's sit.

Frequently asked questions

What is 963 Hz used for?

In the solfeggio tradition, awareness, oneness and a sense of the whole. In practice it is a morning and meditation tone, played very softly over a low drone, and it is the tone people most often ask us about after seeing it in a video.

What does 963 Hz sound like?

A thin, bright, almost crystalline tone near B5, the highest in the set. On its own it can feel sharp within a minute, which is why it is always used over something low and at a low volume.

Is 963 Hz good for sleep?

No. It is the brightest tone of the nine and stays firmly in the foreground. For sleep use 174 or 285 Hz under rain.

How loud should 963 Hz be?

Quieter than any other tone in the set. Set it to where you can just hear it over the drone, then lower it one more step.
