Simple Discussion of music

Simple Discussion of music

The so-called music is like the principle of being a person. The world of only one person does not need any truth at all,
A reasonable specification is required only when most people exist. Therefore, music is a collection of many notes.
Leli is studying the specifications in music.

First, let everyone know how many notes are currently used in music? Simple
First of all, you only need to know 12 audios. We can arrange the piano and keyboard with seven white keys and five
Black Keys are repeated in units. In fact, don't underestimate this, from J. S. Bach to 10.
Since the establishment of the 12th average law in October, the later-generation composite used the twelve voices as the standard for music creation.
. Although its process and changes are not so simple and simple, they are very important and basic concepts,
We will continue our in-depth discussion.

After talking about the twelve voices on the piano and keyboard, you should be curious about how this was made.
. Here we will talk about the problem of temperament. Sound is produced by vibration, frequency
The speed and slowness indicate the sound level. There is a very important relationship between sound harmony and frequency ratio,
For example, the frequency ratio of octal is, the full five degrees is, and the big three degrees are ..., Basically, the number is restored.
The smaller the proportion, the more harmonious it is called just intonation ). However, in a big three-degree cycle
For example, if you drop A, C, E, and # G, dropping a and # G will not become octal, but slightly different. To solve
In this case, an equal temperament is generated, which divides an octal value into twelve
The minimum distance between the sound and the sound is half. This does solve many technical problems,
It is not ideal for our hearing. This is not a problem for people playing keyboard instruments,
It is a test for the performance of major, violin, and other stringy instruments.

The most famous use of the mean law is the J. S. Bach average law piano set (the wel
L-tempered clavier), a total of 48 Prelude and compound songs, that is, each of the 24 major minor notes has two
The song is divided into two parts. This is the first work to achieve the average law.
.

The above is just a brief introduction of the concept of law adjustment. It is not that easy to study in depth,
It even requires a deep mathematical foundation. Therefore, this topic will be held here.
Tonality.

★Tonality)

Tonality is a minor in 24. But how did this happen? First
We should have some knowledge about scales. Basically, Western music is based on the seven scales.
We can see from the spectrum that the notes are arranged in the order of line and line, and only C, D, E, F, G, A, and B are obtained.
Seven different audio names. However, we have mentioned that there are 12 different audios in general, because
The distance between the above seven audios is not half. Take c, d, e, f, g in C major as an example.
, A, B, and C * are arranged apart from E, F and B, and C * are semi-phoneme, and all other sounds are complete.

You need to know that most classical music has been created since the baroque period.
Sexual music is dominant. Although atonal music is produced in modern music
Or are you familiar with tonality music. However, pop music is still unable to adjust its tonality. Why?
So what? For example, if a person goes out from home, no matter how far he goes, or how long he wants to leave,
Finally, we should always go home again. In tonality music, the most important thing in each tone is tonic ),
The music usually starts from the main or main chord and ends with a return to the main or main chord. This mode is the most important
The significance is to make music have a strong sense of direction.

The source of this sense of direction lies in the arrangement of scales. We call the distance between two notes as the phoneme, for example
If the phoneme of each note in a scale is the same, the distance between the notes is the same.
Points of intimacy. In this way, there is no trend and there is no direction to proceed. So we can
The importance of the two groups of half phoneme positions in the size adjustment. The following lists the audio names in the scale in sequence: Main
Tonic, supertonic, Mediant, subdominant
Dominant, submediant, and guide ?? Leading tone) and octal music (Ave ave ).

From this we can see that each of the twelve voices can become the main voice of a Single Tone, so we can get 12 major and 12 major
In total, there are Twenty-four major minor notes.

Chord

Three chords:

A three-chord is a chord formed by overlapping three tones. The Bottom Sound Of a chord
For the root sound, the root sound is called the third sound, and the root sound is called the fifth sound.

(1) major chord. The root voice and the third voice are separated into three vertices.
String.

(2) Minor three chords. The root voice and the third voice are separated into three degrees, and the root voice and the fifth voice are separated into three
String.

(3) subtract three chords. The root voice and the third voice are separated by three degrees, and the root voice and the fifth voice are separated by three degrees.
String.

(4) Increment three chords. The differences between the root voice and the third voice are greater than three degrees. The difference between the root voice and the fifth voice is increased by three degrees.

String.

Seven chords

The composition of a seven-chord is a chord consisting of four sounds stacked in three degrees. It is characteristic of a root chord.
The distance from the top voice is seven degrees, hence the 7th chord.

(1) Big, small, and seven chords. Based on the three major chords, the distance between the root and the seven is a small seven-degree chord. Also
It is called a 7-chord.

(2) Big seven chords. Based on the three major chords, the root and seven major chords are separated.

(3) Minor seven chords. Based on the minor three chords, the distance between the root and the seven is the minor seven-degree chord.

(4) subtract seven chords. Based on the three-chord reduction, the distance between the root sound and the seven sound is the seven-degree Reduction chord.

(5) Reduce the 7th chord. Based on the three-chord reduction, the distance between the root and the seven is the same as that between the seven degrees. Also
It is called the Guide 7 chord.

12 average law

The twelve average Law refers to dividing the eight-degree audio range (2x frequency range) into twelve equal portions by frequency and other proportions.
Each level is called a half tone, that is, a secondary level. A large two degrees is a two-equal copy.

It is amazing to divide an octal value into 12 equal portions. Its pure five-degree phoneme has two
The frequency ratio (that is, the 7/12 power of 2) is very close to the 1.5 power, and the human ears basically cannot hear the "five degrees of parallelism"
The difference between the five-degree intervals of the Law and the twelve-year average law. At the same time, the pure quartile and
The frequency ratio of two audios is close to that of 4/3 and 5/4, respectively. That is to say, "12-day average
The main chord notes of the law are consistent with those of the natural panic sequence, only
A very small difference, which provides the necessary conditions for the use of key playing instruments such as the trumpet in the band, because
Some instruments rely on natural panic levels (as described above, the frequency of natural panic sequences is an integer of the pitch frequency.
To form a scale.

The twelve average law is widely used in the symphonies and keyboard instruments, because only the twelve average
To facilitate the transfer.

It seems that the first person who accurately uses a mathematical method to calculate the audio ratio of the "twelve-average law" is me.
A musician surnamed Zhu from the Ming Dynasty. This is also a great tribute made by our people for world music.
.
Sonate

The sonate is a form of music (nonsense:-d), that is, a style of music writing.
A relatively fixed frame to frame a piece of music, so that a piece of music with a fixed curve has a comparison
The regular form facilitates the listener to understand and appreciate it.

Music is invisible. How can this framework be viewed? It depends on repetition, variation and comparison.
Elements. As long as you grasp these three points, listening to music won't be confused.

Because music is a transient kind of stuff, it is important for a musician to repeat some music, rhythm, or something.
To deepen our impression, but simply repeating is undoubtedly very boring, so we need to change it. This is
Variation.

The most common variation is to change the rhythm, sound, tone, and decorative sound on the basis of retaining the melody.
Means to change the effect and mood of Music (you have heard of the <animal carnival>, and a cheerful march is greatly
After slowing down the pace, it turns into a <tortoise>, which is quite cool.) Complicated variations are chaotic. What are the elements?
Of course, some features of the prototype have changed. Otherwise, it will not be a variation.

The comparison adds a dramatic factor to the music. Two emotions, different effects of music appear successively.
Is it interesting to depeat, tangle, and integrate with each other?

So we can talk about the sonata. The sonata is a large music style.
The development of Mozart and the perfection of Beethoven have become major factors such as the symphony, sonate, symposion, and chamber music.
It is also called the "Sonata-
The first music style "or" Sonata-Allegro.

Its structure is divided into three main sections from the outline: presentation, expansion, and reproduction.
Sorrow> let's talk about the first movement.

The presentation part raises the topic of this music movement. Generally, there are two themes here to achieve the effect of comparison.
If the theme is a piece of music, do not be intimidated by these terms.
And the secondary topic, or for short, the topic and subtopic. The topic is fast, powerful, heavy, and crude.
Hope to hold you down, and the sub-questions are often written as gentle as a song, it is a pity (think of "contrast" This element
In order to increase the complexity of music, it seems that the composer is not a straw package: sometimes at the beginning of the presentation
Child; write a piece of music between the subject and subquestions, which is often referred to as "connection Department" or "plug Department"; end with the subquestion
Add a tail called "end part". The "end part" here is the "end" of the Presentation part, not the whole
The "end" of the sonata.

In the first movement of <grief>, greenfir? :->) Music with a low haze is a reference
Child; The following fast and disturbing melody is the topic. After it is repeatedly replayed and changed,
The warmth to the hearts of people go to the melody:

3 2 1 | 6 5 3 5 1. 6 | 5-... this is a supplementary question.

-------------

The sub-questions were repeatedly repeated and changed, with gentle and warm voice. Finally, the presentation ended with a peaceful ending part.
Music.

On the basis of the two themes of the presentation department, expand the Department to write many new things based on some people's behavior.
It is called "development". According to our old Chinese novels, it is "perfunctory writing ".
Fast and impulsive, after several ups and downs, the expansion ended.

As the name suggests, the reproduction Department repeats the topic subquestions (in fact, the presentation Department ).
Point changes, otherwise it seems that the composer is not very competent? Sometimes the reproduction part is simplified, introduced, and inserted.
Class is removed. A tail sound is often added to the tail. The reproduction part of <grief> is complete. First, it is strongly
The melody of the subject is reproduced, and then changed once, and the connection between the subject and subquestions is reproduced.
The voice of the sub-question is different from that of the Presentation part, and the "End Part" is also reproduced.
. A gentle ending is added at the bottom.

So far, an example of a complete sonata is over.
