Using, Creating and Editing Voices Changing Pitch Cent: In musical terms a "cent" is 1/ 100th of a semitone. (100 cents equal one semitone.) Instantly recalling the desired scale Register the desired scale to the Registration Memory. Be sure to checkmark the SCALE item when registering (page 135). 4 Change the following settings as necessary. • Tuning the individual notes of the keyboard (TUNE) 1 Press the [3π†] button to select the note for tuning. 2 Use the [4π†]/[5π†] buttons to set the tuning in cents. • Determines the base note for each scale. Press the [2π†] button to select the base note. When the base note is changed, the pitch of the keyboard is transposed, yet maintains the original pitch relationship between the notes. Preset Scale Types EQUAL TEMPERAMENT PURE MAJOR PURE MINOR PYTHAGOREAN MEAN-TONE WERCKMEISTER KIRNBERGER 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 tuning 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. ARABIC Use these tunings when playing Arabic music.
