Temperament
Modern pianos employ a tuning system called “Equal
Temperament,” which is also used by your digital piano.
Equal Temperament, however, is a relatively new tuning
system, and different temperaments were in use during the
times of Bach, Beethoven, and Chopin.
Your digital piano comes with the seven temperament settings
listed below, which adjust the tuning of the keyboard to suit
a variety of classical pieces.
Use the keys shown below to change the temperament setting.
