444 Hz: a bright tuning pitch

A4 = 444 Hz is occasionally used by orchestras and soloists who want a brighter sound than 442. It is a choice, not a standard, and an ensemble has to agree on it before anyone tunes.

• Open the tuner at A = 444 Hz

Which note 444 Hz is at other reference pitches

“In tune” depends on what A4 is tuned to, so the same frequency is a slightly different distance from the nearest note in each tuning.

Octaves of 444 Hz

Doubling a frequency raises it an octave and halving lowers it one, so these all have the same note name and the same offset from it.

Period and wavelength

One cycle of 444 Hz lasts 2.252 milliseconds; in air at 20 °C, where sound travels at about 343 metres a second, one wavelength is 77.3 centimetres.

Convert another frequency

Or hold 444 Hz as a steady tone, sweep from it, or beat it against a second tone in the tone generator. The note frequency chart lists every note from C0 to B8.
