The origin of the seven tone scale 20, the origin of the seven tone scale

The 12 equal temperaments, also known as the "12 equal rhythms", are a common system in the world that divides a group of tones (octaves) into twelve semitone intervals, and the ratio of the vibrations between the two adjacent rhythms is exactly equal. The twelfth equal temperament refers to the division of octaves (octaves) into twelve equal parts in proportion to the frequency, and each equal part is called a semitone, or minor second. A major second degree is divided into two equal parts.

Dividing an octave into 12 equal parts has some surprising coincidences. The frequency ratio of the two tones of its pure fifth interval (i.e., the 7th and 12th power of 2) is so close to that the human ear is basically inaudible to the difference between the fifths of the "fifths" and the "twelve equals". The 12 equal temperament is widely used in symphony orchestras and keyboard instruments, and the piano today is based on the 12 equal temperament.

As for what you said.

The pure fourths and major thirds of the "Twelve Equal Temperaments" have frequency ratios that are close to 4 3 and 5 4 respectively. That is to say, the main chord notes of the "Twelve Equal Temperaments" correspond to a few notes in the natural harmonic sequence, with only minimal differences, which provides the necessary conditions for the use of key wind instruments such as trumpets in the orchestra, because these instruments form the scale by natural harmonic scales (natural harmonic sequences whose frequencies are integer multiples of fundamental frequencies, in a sequence of equal differences). The semitone is the smallest pitch distance in the twelve equal temperament organization, and the whole tone is made up of two semitones.

1- Divide into 12 servings. Specific 1-2 whole tones, 2-3 whole tones, 3-4 semitones, 4-5 whole tones, 5-6 whole tones, 6-7 whole tones, 7-i semitones.

The semitone of the twelfth equal temperament is greater than the semitone of the law of fifths, and smaller than the pure temperament. Therefore, the use of 12 equal rhythm chords is impure and the melody orientation is not enough, so in the performance of the piece, especially when the orchestra is played in a multi-part ensemble, it is actually used in multiple rhythms, and according to the actual situation, in the performance process, it is biased towards one rhythm, which is not immutable.

Seven-tone scale: A scale made up of seven adjacent notes.

Because 4 and 7 are dissonant, don't you think it sounds like a transition tone?

There are only seven notes on the scale, because the ancients believed that when the frequency ratio between two tones corresponds to 2:1 (pure octave), 3:2 (pure fifth), 4:

At the three ratios of 3 (pure fourth), you can hear a more harmonious sound. The seven tones in the basic scale are the product of the combination of the twelve equal temperaments and the fifths of the symbiotic temperament.

The 12 equal temperament divides an octave into 12 equal parts, creating 12 chromatic scales, which determines which of them is basic and which is varied, which is borrowed from the law of fifths.

The fifths of the rhythm is based on the comparison of half and one-third of a fixed string, this ratio is the pure fifth in the interval, the ratio is two-thirds, and the seven-tone of 4, 1, 5, 2, 6, 3, 7 is obtained by continuously taking two-thirds of a string (and then taking it down, there will be a change of scale), although it is not on an octave, but combined with the twelve equal temperament, you can get 1, 2, 3, 4, 5, 6, 7 on the same octave.

The 12 equal temperaments are the world's most common system in which a set of tones (octaves) is divided into twelve semitones, and the ratio of the number of vibrations between the two adjacent rhythms is exactly equal. It divides a pure octave (e.g., c1 c2) into twelve equal parts, each of which is called a semitone, and is the main tuning method. Among them, the piano is set according to the twelve equal laws.

The four partial tones in the seven-tone mode are the variable sign tuan macro (a minor second below the sign sound), the change gong tone, the clear angle, and the leap (a major second below the gong tone).

The seven-tone scale is arranged in high and low order from the main tone to the main tone, which is called the seven-tone scale. There are a total of 15 seven-tone modes, including 5 types of Yale scale, 5 Qingle scale, and 5 Yanle scales.

Compared with pentatonic mode, the seven-tone mode is characterized by the addition of intervals of semitones and tritones. The seven-tone pattern can likewise be illustrated by the relationship between fifths or fourths.

It is formed by the original pentatonic scale gong, shang, jiao, sign, and feather (cdega) with two tones (cde fgab).

The seven-tone scale is a scale consisting of seven adjacent tones within an octave. Ecclesiastical scales were prevalent in the Middle Ages, and their composition and names are of Greek origin, with four modi

Doric key (Dorian) d d'；Phrygian e e'；Lidian F f', and Mixolidian G G'。Later, two more positive forms were added, namely the aeolian (a-a).'and Ionian g g', the latter two are the predecessors of the modern major and minor scales. In modern times, the major and minor scales prevail since the ten.

VI and XVII centuries to the present.

Seven-tone scale: A scale made up of seven adjacent notes.

Qingle scale: It is composed of Gong, Shang, Jiao, Qingjiao, Zheng, Yu, and Changgong.

Yale scale: It is composed of Gong, Shang, Jiao, Change, Sign, Feather, and Change.

Yanle scale: It is composed of gong, shang, jiao, qingjiao, zheng, feather, and leap.

It is a scale made up of seven adjacent notes within an octave. During the Warring States period in China, there was already a seven-tone scale, which was formed by the original pentatonic scale gong, shang, jiao, zheng and yu (cdega) and the two tones of change sign and change palace (cde fgab).

It looks like a pentatonic scale.

Orthophonic scale, lower scale, Qingshang scale.

A scale is a string of tones arranged in a sequential order of whole tones, semitones, and other intervals. The basic scale is a C major scale, and it is played on the piano with white keys. The scale is divided into "major scale" and "minor scale", i.e., "major" and "minor".

The major scale consists of 7 tones, where between the first notes and between the first tones are chromatic intervals, and between the other tones are full intervals. The interval between the first notes and the tones of the minor scale are chromatic intervals.

Regarding the origin of **, scientists call it the product of "heterosexual courtship". This statement was put forward by the famous British biologist Charles Darwin. This doctrine was a sensation at the time.

Darwin believed that prehistoric animals often pursued the opposite sex by chirping. The more beautiful their voices are, the more attractive they are to the opposite sex, so that animals have to make graceful and beautiful sounds to win each other's favor, and this song, especially the song of birds, has a musical or rhythmic element. Thus, Darwin thought about the origin of the **, arguing that sound existed before language was created.

The songs of some ethnic groups in the primitive tribes imitate the chirping of various birds, the moving chirps, and the undulating melody, thus forming beautiful folk songs that have been sung for centuries. In particular, the song of birds has an element of music or rhythm. Thus, Darwin thought about the origin of the **, arguing that sound existed before language was created.

The name and composition of the Yanle scale are: Gong,

Shang, Jiao, Qingjiao, Zheng, Yu, Leap, Palace.

The names and compositions of the Yale scale are: Gong, Shang, Jiao, Change, Zheng, Yu, and Change.

Extended Materials. Each key of the Yanle Tonggong system.

The Yanle key is made by adding clear angles and intercalations on the basis of the pentatonic scale. It is also known as the Qing Shang scale or the folk music scale.

Since all five positive tones can be used as the main tone, five Qingle keys can be produced on the basis of the Yanle scale

3. The various keys of the Yale Tonggong system.

The Yale key is based on the pentatonic scale by adding signs and palaces. Also known as the orthophonic scale or archaic scale.

The composition of its musical scale is: Gong, Shang, Jiao, Change, Zheng, Yu, and Change.

Since all five tones can be used as the main tone, five chiraku keys can be produced on the basis of the Yale scale:
