2. The MICROTUNING Page
This page, accessed with PAGE+, provides a selection of preset intonation scales
(temperaments) and four programmable ones.
Several of the scales available are historic and are suitable for those interested in the
creation of antique music.
The small keyboard in the right part of the display shows how each
note of any Intonation scale differs with respect to the same note
of the Equal scale.
For example, if you select the Mesotonic scale and play every note within an octave, the
small keyboard will display, for every note, the difference in 64th of a semitone with
respect to the same note of the Equal scale (0). The display will show the following:
Play any note C#:
Play any note D#:
The Intonation scales:
EQUAL TONE: this is the standard temperament and is the scale currently in use
(since the Bach era) - it provides the standard for modern
“Western” music based on the note A = 440 Hz.
INVERSE: inverts the keyboard - the higher notes on the left, the lower notes
on the right.
MESOTONIC: temperament in use during the 16th and 17th centuries which
favoured the perfect major third interval with respect to that of
the fifth. Calculated from the note C, the chromatic scale is very
irregular. The usable scales of this temperament are: C. Maj. / D
Maj.. / G Maj.. / A Maj.. / Bb Maj. and the relative minors.
WERKMEISTER III: temperament suitable for the execution of the German
musical repertoire between the end of the 17th and 18th century.
ARABIAN 1 & 2: two Arabian scales based on the reduction by one quarter of a
tone of one or more notes of the scale.
PROG 1, 2, 3, 4: four positions for user-programmable scales.
The note C# is shown to
be -16 units lower than
the same note of the
Equal scale
The note D# is shown to
be 7 units higher than the
same note of the Equal
scale
