How to Use a Tuning Fork (and Which One to Buy)

A tuning fork takes ten seconds to use, but almost everyone does it wrong the first time — and improper handling can permanently detune the instrument. Here's the correct way.

The four-step process

  1. Hold it by the stem, the part that extends from the bottom. Never by the prongs. A prong held between the fingers won't vibrate: the sound dies immediately, and many people conclude their tuning fork is defective.
  2. Strike a single prong, with a sharp blow, using the mallet provided. A clean strike is better than a hard strike.
  3. Bring it close to one ear, five to ten centimeters away, without touching. Then switch to the other ear.
  4. Listen until the sound completely fades. This is the only rule that matters. It takes about forty seconds.

The table trick

Place the base of the stem against a wooden table, a door, or a board while the tuning fork vibrates. The furniture will vibrate with it and act as a soundboard: the sound becomes much more present, at the cost of a shorter duration.

This is the same principle as the optional resonance box sold with some models. A solid wood table works perfectly, for free.

The three mistakes to avoid

  • Striking against a hard surface. Table, wall, furniture corner, bony knee: the impact deforms the metal, the tuning shifts, and it's irreversible. Use only the mallet or the fleshy palm of your hand.
  • Dropping it. Same consequence. That's why a case is provided: a tuning fork should not be stored loosely in a drawer with keys.
  • Touching it against skin or bones. Some people do this, but an unweighted tuning fork is not designed for it: it will stop vibrating on contact, and you risk detuning it. Models designed for body application are weighted, heavier, and more expensive.

What to check before buying

  • The material. Aluminum alloy for a listening tuning fork: lightweight, clear sound, long note. Steel produces a shorter, drier note.
  • The mallet. Without a mallet with a rubber head, you'll end up striking something hard. If it's not included, the advertised price isn't the true price.
  • The case. Same reason. A tuning fork without a case will go out of tune within a year.
  • The engraved frequency. It should be engraved in the metal, not printed on the packaging.
  • The seller's claims. If the product description promises DNA repair or healing, steer clear: these claims are prohibited in Europe, and a seller who writes them hasn't checked much else. We explain why here.

The price

In France, a listening tuning fork with mallet and case costs between €25 and €50. Below €15, the tuning is often approximate and the sound metallic. Above €60, you're paying for a brand or a weighted model intended for professional use.

When to use it

The best use we know is also the simplest: one strike to begin your break, one strike to end it. In between, you do nothing. The sound replaces the timer, and it's much more pleasant than a phone alarm.
