The method of a professional tuner

Preliminary assessment

The tuner begins by listening and playing several notes to assess the overall state of the tuning and identify unstable strings.

Temperature control

He allows the piano to adapt to the temperature and humidity of the room, in order to avoid rapid dissonance after intervention.

A4 Agreement

Traditionally, he uses a tuning fork to set the reference to 440 Hz, but some use a electronic tuner for greater consistency.

Equal temperament

From this reference note, he tunes the other notes by intervals (fifths, fourths, octaves) while ensuring harmonic balance.

Finishing touches and double check

Each string is checked, adjusted if necessary, then the tuning is stabilized to last several months.
