128 Hz, 256 Hz & 512 Hz Master Tuning Fork Set of 3 - Weighted
$209.97$178.47
A foundational three-fork set for grounding, harmonic exploration, focused listening, and body-based vibrational sound work.
The Master Fork Set brings together 128 Hz Master Fork 1, 256 Hz Master Fork 2, and 512 Hz Master Fork 3 to create a simple three-frequency progression built around octave relationships.
The weighted design of all three forks produces pronounced tactile vibration, making the set suitable for practitioners who incorporate direct-contact tuning fork techniques alongside focused listening and non-contact sound work. Together, the three frequencies provide a versatile foundation for exploring lower, middle, and higher harmonic tones.
Within the system, 128 Hz Master Fork 1 is also known as the Otto 128 in its weighted form. The 256 Hz and 512 Hz forks are also part of the Fibonacci Tuning Fork system, connecting this three-fork set to a broader framework of mathematical ratios and musical intervals.
Frequencies: 128 Hz • 256 Hz • 512 Hz
Type: Weighted
Material: Premium Aluminum Alloy
Ideal for: Body-Based Vibration • Harmonic Sound Work • Grounding Practices • Focused Listening • Frequency Exploration • Practitioner Training
Made to Order
Each set is made to order. Please allow up to 3–4 weeks for delivery.
The Master Fork Set creates a three-frequency progression in which each frequency doubles the one before it.
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 128 Hz, 256 Hz, and 512 Hz follows a simple octave progression. Each frequency is double the previous frequency, creating clear harmonic relationships across the three forks.
The 128 Hz Master Fork 1 is known as the Otto 128 in its weighted form and as the Flower of Life Tuning Fork in its unweighted form.
The 256 Hz Master Fork 2 and 512 Hz Master Fork 3 are also core frequencies within the Fibonacci Tuning Fork system. In this framework, 256 Hz represents the 1/1 reference and 512 Hz represents the 2/1 ratio, creating an octave relationship. The broader Fibonacci system also includes 384 Hz at 3/2 and 426.7 Hz at 5/3.
The Fibonacci relationships described here are based on mathematical ratios and musical intervals. Their use in contemporary tuning fork practices is primarily musical, harmonic, and contemplative, rather than a scientifically established effect of individual frequencies.
Key Benefits
Complete 128 Hz • 256 Hz • 512 Hz Master Fork progression
Weighted construction provides pronounced tactile vibration
Creates clear octave relationships between all three frequencies
Includes the Otto 128 Master Fork 1
Includes 256 Hz and 512 Hz Fibonacci frequencies
Suitable for body-based vibrational techniques and focused listening
Provides a versatile foundation for practitioner sound work
How to Use
Strike each 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.
Use the frequencies individually or explore them progressively, beginning with 128 Hz, moving to 256 Hz, and finishing with 512 Hz. Allow each tone to resonate fully before introducing the next frequency.
The three forks can also be incorporated into Fibonacci-based sound practices, harmonic exploration, meditation, and practitioner-led sound sessions.
