Traditional practice
What it is
A 963 Hz sine tone, close to B5. In the modern Solfeggio set it is the highest of the nine tones.
What users may experience
Light, shimmering and clearly pitched. Most listeners prefer it quietly on top of a low base.
Traditional associations
963 Hz is described in Solfeggio and chakra traditions as a 'crown' or 'return to oneness' tone. That framing is symbolic and cultural, not scientific.
Sound & relaxation
Hearing is very sensitive near 1 kHz, so this tone reads as present even at low volume — useful as a quiet accent that does not mask the base layer.
How to use it
Layer at low level over 111 Hz, 174 Hz or 432 Hz for 10–20 minutes.
Suggested session length
10 · 20 minutes — listening style: Accent layer; intensity: steady.
Safe listening
Bright tones can cause listening fatigue. Keep the volume low and stop if your ears feel strained.
