Medeli SP4000 [31/32] Scale tuning system

Scale Tuning System

A tuning system is the system used to define which tones, or pitches, to use when playing music. In other words, it

is the choice of number and spacing of frequency values used. The equal temperament (has only one tuning

method, and is suitable for keyboard) is the common musical scale used at present, used for the tuning of pianos

and other instruments of relatively fixed scale. One of the advantages of the equal tempered scale is that it is the

same in any musical "key", so that compositions may be freely transposed up or down without changing the

musical intervals. Especially for piano, equal temperament is widely used and taken for granted. But people used

several other scales to compose and perform before adopting the equal temperament. This piano has been

equipped with 6 scale tuning systems, you can select one to reappearing its matched chord of the melody at that

time.

Characteristics of Different Scale Tuning Systems

Pythagorean

The Pythagorean tuning, named after the ancient mathematician and philosopher Pythagoras, is based on a stack

of intervals called perfect fifths. It is particularly well suited to music which treats fifths as consonances, and thirds

as dissonances.

Pure Major & Pure Minor

In music, just intonation (sometimes abbreviated as JI) or pure intonation is any musical tuning in which the

frequencies of notes are related by ratios of small whole numbers. Any interval tuned in this way is called a pure

or just interval. And the major scale which consisted of just intonations especially for this triad chords: Root, Third,

Fifth are sounded extremely harmony. The just intonation must be the most natural temperament.

Meantone

The Meantone System is a musical temperament which is close to just intonation. Used to tuning pipe organ in

16th century Europe. These musical scales which based on the Pythagorean System, minus quarter of common

comma for once, are extremely approaching just intonation. So, use this system to create musical scales are

sound beautiful and pure, just like a perfect triad chord.

Werckmeister

The Werkmeister was named after Andreas Werckmeister, and this scale was created as an improvement on the

Pythagorean scale. This tuning collapse comma maxima, created by Pythagorean, into four perfect fifths, the rest

fifths still remain their Pythagorean scale characteristics. Werkmeister Tuning can tune scale from harmonic to

melodic by increasing tone number, making each tonality sound distinct, this is the important gist for classicists

and romanticism tonality music to name the tone name.

Kirnberger

Kirnberger temperament is an irregular temperament developed in the second half of the 18th century by Johann

Kirnberger and regarded as an improved version of Meantone temperament. It makes possible to switch different

tunes freely when performing.

Twelve-tone equal temperament

In twelve-tone equal temperament, which divides the octave into 12 equal parts, the width of a semitone , i.e. the

frequency ratio of the interval between two adjacent notes, is the twelfth root of two. There is minute difference of

the same amount between each two intervals.
