Playing Using Classical Tuning ;
[Playing Using Baroque Pitch]
Currently, standard pitch is determined as
being that where A = 440 Hz. However, in the
Baroque period, it is believed that standard
pitch was that where A = 415 Hz.
Follow the procedure below in order to play
using the standard pitch of the baroque period.

2. Adjusting to Suit Your Preferences
Setting the Tuning Curve —_y
(Stretch Tuning)
Stretch Tuning refers to a method of tuning
specific to pianos.
A piano is ordinarily tuned so that, in compari-
son with the pitches of equal temperament,
the lower range notes are made lower and the
higher notes are made 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. You can
choose whichever curve suits your purpose.
A natural tuning curve, with most wavering
suppressed.
A tuning curve which tends to emphasize the
lower notes. This acts in compensating for the
fact that the lower notes are often perceived as
being higher.
This tuning curve places emphasis on both lower
and upper ranges.
* Even when a temperament other than Equal is selected,
the setting for the Tuning Curve that has been made
will remain in effect.
