174–963 Hz Solfeggio Unweighted Tuning Fork Series

• Single-frequency option: one fork at the selected frequency.
• 9 Solfeggio Set: all nine listed frequencies, one fork of each.
• A storage pouch and rubber mallet are included with each fork.
• Photos of the full collection do not mean that a single-frequency option contains nine forks.

The names and themes used in modern Solfeggio practice are symbolic interpretations. The benefit described here is how you can structure a listening routine; these frequencies do not guarantee relief from pain, anxiety or another condition.

174 Hz — a lower starting point

The lowest tone in the collection. A useful choice if you prefer a lower register and want a simple sound cue for settling into a quiet space.

285 Hz — a step upward

Between 174 and 396 Hz. Explore a mid-low tone and use it to mark a reset between activities; the theme of renewal is a personal practice choice.

396 Hz — reflection

A lower-middle tone often given a theme of release in modern sound practice. Use it before journaling or a mindful pause without expecting a prescribed emotional response.

417 Hz — transition

Only 21 Hz above 396 Hz, but a distinct pitch. Use the contrast to explore nearby tones or mark the change from work to rest.

528 Hz — attentive listening

A middle tone in the nine-fork sequence. Use it as a focus for noticing the beginning, fading sound and return to silence; claims of DNA repair are not established for this product.

639 Hz — shared presence

A higher-middle tone that can accompany a shared listening moment. Invite another person to describe what they hear; connection is a practice theme, not a frequency-driven promise.

741 Hz — a cue before focused activity

A brighter tone for a brief pause before reading, writing or another quiet task. The useful benefit is the repeatable cue to begin; it is not a detoxification treatment.

852 Hz — contemplation

One of the higher tones, between 741 and 963 Hz. Choose it if you enjoy a brighter pitch for meditation or an intention-setting ritual.

963 Hz — the upper end of the sequence

The highest tone of the nine. Its contrast with 174 Hz is easy to explore when played separately; use it as a closing cue and leave a moment of silence afterwards.

A single fork is enough to learn the basics. Choose the set when you want to compare the full range, vary a session or use several distinct cues in a personal or studio routine. There is no requirement to play all nine in one sitting or in a fixed order.

• One-piece CNC-machined 2A11 aluminium-alloy fork body, with a silver-tone finish.
• Unweighted forks: frequency tolerance within ±1.5 Hz at 20°C.
• Each fork is tuned and frequency-checked before dispatch. Ask our studio about testing if you would like more detail.

Our independent studio coordinates specifications, production, tuning, inspection, engraving and packing. Custom frequencies and quantity orders are welcome; confirm feasibility and timing before purchase.

• Hold only the handle. Keep the prongs and any tip weights free.
• Activate with a gentle tap from the included rubber mallet, or a suitable soft activator placed on a stable table. Do not strike the fork on hard surfaces.
• Listen in a quiet space at a comfortable distance. Let the tone fade before repeating.

Keep dry, wipe with a soft cloth and store in the included pouch. Avoid drops, impacts and use on injured or irritated skin. Stop if uncomfortable.
