Otto C 128 Hz Tuning Fork for Sound Healing Therapy

Choose by intention—start simple, start steady:
• 136.10 Hz (OM) – Centering, breath-led calm, inner balance.
• 128 Hz (weighted classic) – Reliable on-body release for tight spots.
• 528 Hz (unweighted favorite) – Uplift/renewal with a bright, heart-forward tone.

Angel tones (4096 / 4160 / 4225 Hz) are beautiful add-ons for clarity.

If you want a structured path with real body feel, choose weighted first.

• Chakra Weighted Set – A root-to-crown flow you can feel on the body; perfect when you blend energy work with gentle somatic release.
• Solfeggio Weighted Set – The beloved Solfeggio path, optimized for on-body application; great for pattern release, renewal and uplift.
• Solfeggio Unweighted Set – Add later for room-filling meditation and biofield harmonizing (pairs beautifully with your weighted set).

Tip: many practitioners pair Chakra Weighted with Solfeggio Weighted. They are not the same frequencies, which makes the toolkit complementary and complete.

Chakra Weighted Set works through planetary frequencies for complete energetic alignment - root to crown chakra balancing.

Solfeggio Weighted Set (9 forks) combines the 6 original sacred tones (396-852 Hz) with 3 additional frequencies (174, 285, 963 Hz) for comprehensive healing applications - from pain relief to spiritual connection.

Many customers love the duo: Chakra establishes balance and flow; Solfeggio targets where you want to go deeper—an all-in toolkit for physical, emotional, and spiritual work.

One fork can serve a focused intention (e.g., 174 Hz soothing, 528 Hz renewal, 136.10 Hz inner peace).

Choose a Chakra or Solfeggio set if you want repeatable, guided protocols from day one—weighted first for on-body depth.

Strike gently on a rubber activator (never hard edges or fork-to-fork). Hold the stem, avoid touching the tines.

For weighted forks, place the stem lightly on the body and let the vibration do the work; for unweighted, work near the ears or sweep the field.

Breathe slowly and allow each tone to fully fade before the next strike.

For on-body work, add Extension/Resonator Handles to your weighted forks. They:

• Deepen contact and prolong vibration on the body
• Improve precision on acupressure points and tight areas
• Reduce hand fatigue during longer sessions

Note: Handles are designed for weighted forks (on-body use). Limited batches—add while in stock.

Tuning forks add precision and focus, while bowls create rich, immersive overtones.

Layering both engages different aspects of resonance for a deeper, more integrated experience—customers often describe this as “the moment everything lets go.”

Use a rubber activator, store in protective pouches, wipe the stem after oils, and avoid drops/impacts to preserve tuning and finish. Your forks will serve beautifully for years with simple care.

Professionally calibrated to ±0.25 Hz accuracy using CNC-machining and computer verification. Each fork is laser-engraved with its frequency and maintains tuning stability.

Each batch is inspected for tuning consistency and finish quality so your tools look and feel professional in every session.

Premium aluminum alloys, CNC-machined for clean attack and long sustain, smooth edges, and laser-engraved frequency markings. Each batch is inspected for tuning consistency and finish quality.

They’re the same tones by octave relationship, but weighted forks are typically tuned to a lower octave—divided by 2 up to 8 depending on the frequency to optimize tactile resonance on the body (lower frequencies travel deeper and feel smoother on contact).

This octave shift preserves the energetic signature—you receive the same benefits through the corresponding octave, with a more comfortable, long-lasting body vibration.
