ENGLISH Detailed Settings - [FUNCTION] F2. Selecting a Scale You can select various scales. Equal Temperament is the most common contemporary piano tuning scale. However, history has known numerous other scales, many of which serve as the basis for certain genres of music. You can experience these tunings with the P-140. F2.1: Scale Setting range: 1: Equal Temperament 2: Pure Major 3: Pure Minor 4: Pythagorean 5: Mean Tone 6: Werckmeister 7: Kirnberger Default setting: 1: Equal Temperament EQUAL TEMPERAMENT 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. PURE MAJOR/PURE MINOR 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. PYTHAGOREAN 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. MEAN-TONE 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. WERCKMEISTER/KIRNBERGER 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. F2.2: Base Note If you select a scale other than Equal Temperament, you need to specify the root. (You can also specify the root note with Equal Temperament selected, but it will have no effect. The base note setting is effective for tunings other than the Equal Temperament tuning.) Setting range: C, C#, D, Eb, E, F, F#, G, Ab, A, Bb, B Default setting: C • Root indication example (F#) (G) Followed by a high bar if sharp (Ab) Followed by a low bar if flat 40 P-140 Owner's Manual
