128 Hz Otto / Master Fork 1 Tuning Fork - Weighted
$69.99
Explore the foundational resonance of 128 Hz through a weighted tuning fork designed for body awareness, grounding, physical resonance, and intentional sound practice—and recognized as Master Fork 1 within the three-fork Master Tuning Fork system.
The 128 Hz Master Fork 1 Tuning Fork is the first frequency in the three-fork Master Fork system, followed by 256 Hz Master Fork 2 and 512 Hz Master Fork 3. In its weighted form, it is also known as the Otto 128 Tuning Fork and provides the foundational frequency of the system.
Its low, resonant frequency can be incorporated into meditation, sound healing, focused listening, breathwork, and body-based vibrational practices. The weighted design produces pronounced tactile vibration, making it particularly suitable for practitioners who work with direct-contact tuning fork techniques.
Frequency: 128 Hz
Type: Weighted
Material: Premium Aluminum Alloy
Ideal for: Body Awareness • Grounding Practices • Sound Healing • Master Fork Practices • Direct-Contact Sound Work
Made to Order
Each instrument is made to order. Please allow up to 3–4 weeks for delivery.
128 Hz holds a dual position within this collection: it is part of the Otto frequency system and Master Fork 1 within the three-fork Master Tuning Fork system.
Within the Otto Tuning Fork system, 128 Hz is the highest of the foundational Otto frequencies:
32 Hz
48 Hz
64 Hz
128 Hz
Its weighted construction creates a clearly perceptible tactile vibration that can be incorporated into grounding, body-awareness, meditation, and direct-contact sound practices.
The 128 Hz Master Fork 1 establishes the foundation of the three-frequency Master Fork progression.
128 Hz — Master Fork 1 — Foundational Tone — Grounding & Physical Awareness
256 Hz — Master Fork 2 — Harmonic Foundation — Balance & Centered Awareness
512 Hz — Master Fork 3 — Higher Harmonic Tone — Focus & Tonal Awareness
The relationship between these three frequencies follows a simple octave progression, with each frequency doubling the previous one. This creates a clear harmonic structure from 128 Hz to 256 Hz and from 256 Hz to 512 Hz.
The 128 Hz Master Fork 1 is known as the Flower of Life Tuning Fork in its unweighted form and as the Otto 128 when weighted. The 256 Hz Master Fork 2 and 512 Hz Master Fork 3 complete the three-fork progression.
Key Benefits

How to Use
Strike the tuning fork gently with the included striker and allow the tone and vibration to develop naturally.
For body-based techniques, gently place the vibrating stem against an appropriate area using light, comfortable pressure and an established tuning fork technique. Avoid injured, inflamed, or sensitive areas.
For non-contact work, hold the vibrating fork near the body or within the meditation space while listening closely to the sustained tone.
Pair the 128 Hz Master Fork 1 with 256 Hz Master Fork 2 and 512 Hz Master Fork 3 to explore their octave relationships and progressive tonal structure.
