The top of the Solfeggio series: the 963 Hz SI tone
This tuning fork sounds the highest tone of the Solfeggio scale, marked SI, at 963 Hz. The high pitch rings clear and bright: many describe it like the delicate voice of a tiny bell, held for a long time. Tradition links this tone with inner calm and a sense of harmony with nature - a favourite closing tone for sound baths and relaxation sessions.
Small size, easy handling
Higher tones come with shorter forks: this piece is only 11.8 cm long and weighs 74 grams. That makes it especially easy to hold and position precisely - whether you listen to it near your ear or use it during a session. Thanks to its small size it travels comfortably in a bag or instrument case.
Nickel-free steel and maple wood
The fork is made of black oxide, nickel-free steel, safe to use even with sensitive skin. The maple handle feels warm to the touch and gives a secure grip. The fork is made in Germany with careful workmanship so its tone stays pure for many years.
Use it alone or as part of the series
You can use this fork on its own to create a quiet moment, or together with the other members of the Solfeggio series: building up from the lower tones to 963 Hz creates a varied, gradually brightening soundscape. Various wooden stands are available for the forks.
