* Once a setting for the tonic has been made, it will not change even if you change tempera-
ments.
* When you have selected a temperament other than Equal and play in ensemble with other in-
struments, certain discrepancies in pitch may occur, depending on the key being used. In
such cases, use the piano’s Tuning knob to adjust the pitch so it matches the tonic of the
other instruments.
Stretched Tuning
Stretched Tuning refers to a method of tuning specific to pianos.
A piano is ordinarily tuned so that, in comparison with the pitches of Equal tempera-
ment, the lower range notes are tuned slightly lower and the higher notes are tuned
slightly higher.
The Tuning Curve represents the actual pitch changes produced by a particular tuning,
when compared with the pitch changes of Equal temperament.
By changing the Tuning Curve, subtle changes in chord sonorities will be heard.
Choose the curve which suits your particular needs.
OFF (Standard) A natural tuning curve with most wavering or beating suppressed.
I A tuning curve which tends to emphasize the lower notes. This curve
compensates for the fact that the lower notes are often perceived as
_____ being higher in pitch than they actually are.
II This tuning curve places emphasis on both the lower and upper ranges.
