The Otto tuning fork set has three weighted pieces ringing at 32, 64 and 128 Hz, each on a different octave of the C tone. The deep vibrations offer you a way to ground and wind down after a long day. The prongs are 21 to 37.5 centimetres long, the whole package weighs 446 grams, and a 39 x 11 cm blue velvet pouch protects it during travel.
Three C octaves one after the other
Each of the 32, 64 and 128 Hz pieces sings the musical C note on a different octave. The deepest, 32 Hz fork gives an especially strong low vibration that you can feel through the skin. 64 Hz holds the middle, more accessible range, and 128 Hz is the most easily recognised C tone, with a familiar feel for many ears.
Felt vibration on the body
All three forks have weighted ends, with a small metal weight at the tip of the stem. As a result the sound lasts long and the stem placed on the skin produces a vibration you can feel deeply. Sound circles especially value this set, because it gives you a chance to meet the 32 Hz low range, which is hard to find as a single fork.
Size, weight and pouch
The prongs range from 21 to 37.5 centimetres, and the 39 x 11 cm blue velvet pouch keeps them neatly arranged in storage. The whole package weighs 446 grams, which is light for a three-piece set. We gladly recommend it to you also if you need to travel to a sound therapy practice.
Home ritual ideas
Sit comfortably, tap the strong, deep 32 Hz first and rest the stem on the sole of your foot at arm's length. Breathe slowly while the sound fades. After a minute of quiet, ring the 64 Hz, then another minute later the 128 Hz. This gradual building feels especially settling for you.
Good to know before use
The set arrives in a paper bag, and you should always tap the forks on your palm or a soft rubber puck, never on metal. Only this way does the ±0.25% tuning stay clean. The forks are wellness companions, not medical devices. If you are pregnant, wear a pacemaker or had a recent surgery, please ask your doctor first.
