Zen Therapeutic Blue Tuning Fork 67Hz-133Hz
Enter a deeper state of resonance with the Zen Therapeutic Blue Tuning Fork, a precision-calibrated instrument designed to deliver profoundly grounding frequencies in the low range of 67Hz to 133Hz. Striking in both form and function, this oversized tuning fork is ideal for practitioners seeking to integrate deep tissue vibration, nervous system regulation, and energetic balance into their sound therapy or bodywork sessions.
With its weighted design and adjustable frequency range, this fork allows you to customize the pitch by repositioning the included weights along the prongs. The result is a dynamic instrument capable of producing a broad spectrum of therapeutic tones, including resonant favorites like C67, G100, and C133—and everything in between. Whether anchoring a session with low, calming frequencies or exploring more energizing tones near the top of its range, this fork offers rich versatility for vibrational healing work.
Why and How to Use It:
In sound therapy, low-frequency tuning forks are revered for their ability to penetrate deeply into the body, affecting both the physical and energetic systems. When struck and placed near or directly on the body, the fork produces slow, sustained vibrations that promote relaxation, relieve muscle tension, regulate the autonomic nervous system, and help ground scattered or anxious energy.
Common applications include use in Reiki, Vibrational Sound Therapy, massage therapy, craniosacral work, or meditative grounding practices.

Tuning Notes:
• C67 – Venus (Higher Harmonic): Some traditions extend Venus tones slightly upward depending on tuning base
• G100 – Venus (Another Octave); Strong emotional resonance; used in therapies of the heart
• C133 - elevated harmonic of the Moon’s frequency, this tone is often linked with inner reflection, emotional balance, and the nurturing aspects of the divine feminine in planetary tuning traditions.
The Blue fork bridges the physical and emotional realms. Its mid-low frequencies correspond with the heartbeat and natural breathing rhythm, supporting emotional regulation and flow. The color blue is associated with peace, communication, and inner clarity — bringing steadiness to transitions and gentle release where energy feels stagnant.
Use: Employ The Harmonizer mid-session to connect grounded awareness with emotional balance. It helps unify the left and right hemispheres of the brain, supporting coherent states ideal for meditation and integration.
Each tuning fork has the frequency rang notated on the fork for easy reference.
The Vibrational Alignment Set
Experience the full spectrum of sound therapy with three uniquely tuned forks:
• Purple – “The Awakener” (133–263 Hz): Opens awareness and uplifts energy, harmonizing the higher centers.
• Blue – “The Harmonizer” (67–133 Hz): Balances body and mind, restoring calm, flow, and emotional clarity.
• Green – “The Grounder” (32–67 Hz): Anchors and centers, easing tension and creating deep physical relaxation.
Please note: The sound you hear at the moment of striking does not reflect the actual tone of the tuning fork. Due to its low frequency, the true vibration may be difficult to detect through traditional speakers. For the most accurate listening experience, we recommend using quality headphones.
