Pitch-Related Settings

Fine-tuning the Pitch of the Entire Instrument
You can fine-tune the pitch of the entire instrument such as keyboard, Style and Song parts (except the
keyboard part played by the Drum Kit or SFX Kit Voices, and audio playback)—a useful feature when
playing the PSR-S950/S750 along with other instruments or CD music.

The pitch range of each octave is divided equally into twelve parts, with each half-
step evenly spaced in pitch. This is the most commonly used tuning in music today.
These tunings preserve the pure mathematical intervals of each scale, especially for
triad chords (root, third, fifth). You can hear this best in actual vocal harmonies—
such as choirs and a cappella singing.
This scale was devised by the famous Greek philosopher and is created from a
series of perfect fifths, which are collapsed into a single octave. The 3rd in this tun-
ing are slightly unstable, but the 4th and 5th are beautiful and suitable for some
leads.
This scale was created as an improvement on the Pythagorean scale, by making the
major third interval more "in tune." It was especially popular from the 16th century
to the 18th century. Handel, among others, used this scale.
This composite scale combines the Werckmeister and Kirnberger systems, which
were themselves improvements on the mean-tone and Pythagorean scales. The
main feature of this scale is that each key has its own unique character. The scale
was used extensively during the time of Bach and Beethoven, and even now it is
often used when performing period music on the harpsichord.
Use these tunings when playing Arabic music.
The tuning of each note for the cur-
rently selected scale is shown.
