What does 963 Hz mean?
963 Hz is the highest of the nine Solfeggio frequencies, a set of tones used in meditation and sound-healing practices. In that tradition it is often called the “frequency of oneness” and is associated with the crown chakra, deep meditation and a sense of connection and clarity. These are spiritual associations, not medical claims: what you actually get is calm, slow music with a particular tuning.
How this version was made
- Re-tuned: the whole track has been pitched down by 44 cents (a little less than half a semitone), so the note B sits at exactly 963 Hz instead of 988 Hz. Tempo and length are unchanged.
- 963 Hz tone: a soft, pure 963 Hz sine tone runs underneath the music at a low level (about 22 dB below the mix), fading in and out. It is easy to verify with any spectrum analyzer.
The original 440 Hz version of Deepest Healing is available as a separate product. Both are royalty free and come with the same license.
