Chapter 3. Performance
Setting the Tuning Curve
(Stretch Tuning)
Pianos are generally tuned so that the low range is flatter and the high range is
sharper than equal tempered pitches. This method of tuning is unique to the piano,
and is known as “stretched tuning.”
A graph that shows the changes in pitch of actual tuning compared with the changes
in equal temperament pitch is called a tuning curve. Changing the tuning curve
produces subtle variations in the reverberations of the chords you play.
