A little knowledge about music.

I found it somewhere else for reference.

What is music?

This is a matter of opinion, and there are many opinions. The author thinks that music is the art of sound, not the art of vision or other feelings. The art of organizing music sounds according to certain rules (sometimes using noise appropriately) to make people feel wonderful when listening to music is called music.

2. What is noise? What is music?

When vocal cords, strings, boards, motors and other objects vibrate, they will emit sound waves, which will spread to our ears through the air and make us hear the sound. There are two kinds of sounds: noise and music: irregular vibration sounds, such as the sound of boards and motors, are called noise; The vibration is regular, such as the singing of human vocal cords and the piano sound made by strings. , which is the so-called music. The tones used in music are mainly musical sounds.

3. What is pitch?

Music sounds high and low, which is called pitch. Pitch is determined by the vibration frequency of the pronunciation object. High frequency makes the sound high and low frequency makes the sound low. For example, when a woman sings, the frequency of vocal cord vibration is high, while when a man sings, the frequency of vocal cord vibration is low, so the male voice is lower than the female voice.

4. What is the range of tones used in music?

The range of tones used in music is about 97, ranging from the lowest pitch of 16 to the highest pitch of 4 186 per second. The largest piano in modern times can play 88 of them, and it is the instrument with the largest range. Due to physical limitations, the music that people can sing is only a small part of the music range.

5. What is a phonetic name? What do you mean by roll call?

Musical notes with different pitches are represented by C D E F G A G, and these seven Latin letters are the names of musical notes. They are generally sung in turn as DO RE MI FA SOL Ras, that is, 1 2 3 4 5 6 7 in the notation, which is equivalent to the pronunciation of the Chinese character "Domilai Fa Suo Xi". DO, RE, MI ... is the pronunciation of music when singing, so it is called roll call.

6. What is a sound train? How are syllables grouped?

Arrange more than 90 different musical sounds mentioned above to form a sequence, which is called a musical sequence. There are only seven names, but the number of sounds in the series is far more than this. How to distinguish sounds with the same name but different pitches? The method is grouping. People divide the sounds in a series into several groups. The sound group in the central position in the phonetic sequence (that is, the seven sounds starting from the central C in keyboard instruments such as piano and electronic organ) is called the minor group, and the sounds twice, twice and thrice higher than the minor group are called the minor group, minor group, minor group and minor group respectively. Of course, there are also voices lower than the small group, which are divided into the following categories: two times lower than the small group, two times lower than the large group, three times lower than the large group and four times lower than the large group. In this way, the grouping order from low to high in the sound sequence is:

Big characters, two groups of big characters, one group of big characters, one group of small characters, two groups of small characters, three groups of small characters and four groups.

The range of musical tones. The musical term is called register. The vocal range is probably: female voices range from F in small groups to A in small groups, and male voices range from F in large groups to A in small groups. So, how wide is your scope? Try it on the piano sometime. This range is your range from the lowest pitch you can sing to the highest pitch.

7. Which sound is the standard sound?

Internationally, it is stipulated that the A sound of small groups vibrates 440 times per second, which is the standard sound. Because there is a certain quantitative relationship between the tones of a tone sequence, for example, a tone twice as high as a certain pitch (also called octave high) must have a frequency twice as high as a certain pitch, and a tone twice as low as it (also called octave low) must have a frequency twice as low as a certain tone, so the pitch of a standard tone is specified, which is equivalent to the pitch of other tones. With this standard, people have the basis of tuning when making musical instruments, playing music and singing.

8. What is the overall tone? What is semitone?

Divide the distance of the group C D E F G A B into twelve equal parts, and each equal part is called a semitone. If the distance between two tones is two semitones, it is called "full tone" on keyboard instruments such as piano and electronic organ, and C-D, D-E, F-G, G-A and A-B are separated by a black keys, the distance between them is full tone; E-F, B-C, there is no black keys in the middle, and the distance is semitone.

9. What is natural sound? What do you mean by tone change?

Generally speaking, when we sing, those sounds that are sung as 1 2 3 4 5 6 7 are called natural sounds; Tone sandhi is defined as adding # in the upper left corner (such as #4, # 1) or # b (such as b7 and b3). # is called rising tone, which means that the sound is raised by one and a half tones on the original basis; B is called flat semitone, which means to lower the semitone on the original basis.

What is scale?

Centered on one of C, D, E, F, G, A and B, they are arranged from low to high (or from high to low). The order of this sound is called a scale because it goes up or down step by step like a ladder. The following two sequences are scales, the former is a major scale and the latter is a natural minor scale:

c d e f g a b c a b c d e f g a

1 1. What is notation?

A piece of music generally contains elements such as height, length and dynamics. The method of recording these elements on paper with various marks and symbols is called notation. No matter at home or abroad, many symbols have been used and are being used. Take China as an example, there are many kinds of notation at all times and in all countries. It is said that as early as the Warring States period, Shi Juan, a musician in Wei Linggong, recorded music by notation. According to written records, Gongchi spectrum and subtraction spectrum appeared in Sui and Tang Dynasties, and folk character spectrum appeared in Song Dynasty. After several changes, Miyachi notation is still used by folk artists. However, in modern times and modern times, notation and staff are widely used in China, especially notation is used by most people. From a global perspective, the staff is the most widely used.

12, what is the notation?

Notation is a notation for recording pitch with Arabic numerals 1, 2, 3, 4, 5, 6 and 7, which is known to almost all people who have read books in China. This notation was put forward by French monk Suetti in 1665. Later, Rousseau, a famous French philosopher and writer, improved it and actively promoted it. This notation is hardly popular in Europe because it is not convenient to record multi-voice and complex music. About 1882, Mei Sen, an American, introduced it to Japan while giving a lecture. It was used in Japanese schools in the19th century, but they stopped using it later. In the late Qing Dynasty, notation was introduced to China by students studying in Japan. 1904, the book School Singing written by teacher Shen Xingong was published, which was all the rage for a while. Since then, notation has been popularized in China. The author thinks that notation, as a popular recording method, has played and is still playing a huge role in the popularization and promotion of China music. However, because its notation has many limitations, and most countries in the world don't use it now, we should create conditions to popularize the staff in order to improve the music level and communicate with other countries in the world.

What is a staff?

The staff is the most widely used symbol in the world. In the current notation, the staff is the most rigorous, accurate and scientific. It uses five parallel horizontal lines to record the sound level, and a hollow (or solid) ellipse or a figure with a vertical line on its side (some even add a "tail" at one end of the vertical line as a comment to indicate the length of the sound (for example, please see the music score published by this station) has a three-dimensional effect, which is convenient for recording multi-voice music. /kloc-was officially introduced to China at the end of 0/7, and it was introduced in detail in "Continuing the Law and Justice of Lu" compiled by the court during the Kangxi period of Qing Dynasty, which shows that it has been introduced to China for a long time. From 65438 to 0930, the musician Mr. Liu Tianhua recorded the operas sung by Mei Lanfang with the staff, and published Mei Lanfang's Songs, which is the first album in China to record traditional Chinese opera music.

Some people think that staff is more difficult to learn than simple staff. This idea is easy to understand. In fact, the main reason is not that the staff is difficult, but that it is difficult to change the habit of reading music since childhood. All the music you have been exposed to since childhood is notation, and you are used to notation. It's certainly hard to change them now. If you use the staff from kindergarten, so do the music textbooks for primary and secondary schools. The music you usually see is all five elements, and you will get used to it after a long time. At present, many children begin to learn the piano at the age of three or four (you need to use the staff to learn the piano). From shallow to deep, from simple to complex, reading staff and practicing piano go hand in hand. Therefore, although many children are young, their ability to read staff is much stronger than that of many adults. What's the point? Practice makes perfect!

14, what is a serenade?

Articles have various genres, such as narrative, argumentative, poetry, prose and so on. , are all genre articles. There are also various music genres, such as serenades, lullabies, sonatas, waltzes, minuets, polkas, mazurkas ..... all of which are music genres.

Serenade is a kind of music genre, which is used to express love to the beloved. Chivalry literature originated in medieval Europe and spread in European countries such as Spain and Italy. At first, a young man serenaded his lover's window at night and poured out his love. The melody is beautiful, euphemistic and lingering, and he often accompanies it with guitar or mandolin. With the development of the times, its forms have also developed. The serenades created by Schubert and Tosini published in Famous Songs at Home and Abroad are widely circulated all over the world.

15, what is a polka?

The title "Polka" can't summarize and prompt the music content, but it shows that its genre belongs to a kind of dance music in which men and women dance together. Originated from Czech folk, it was once popular all over Europe, and many famous western composers used this genre to create music works. Generally, it is a double beat, and the rhythm is lively and cheerful.

16, what is Mazuka?

It is also a dance music for men and women. It originated in Poland and was once popular in Europe. The biggest difference between it and Polka is that the former is a double beat, but it is a triple beat. Generally speaking, the stress of three-beat songs falls on the first beat of the bar, while Mazuka often falls on the second or third beat. For example, Thomas Mazzuca, published in Simple Music Score, has such an accent in most bars. The emotions expressed by Mazzuca are generally lively and enthusiastic, so we should master this feature when playing.

17, what is a minuet?

Bach's two minuets have been published in Simple Piano Music. In fact, Bach has written more than two works of this genre, and many classical musicians such as Beethoven and Mozart have also written works named after "minuets".

The minuet originated in European courts and was once popular in French courts. It is a kind of dance music in triple time, which is slow in rhythm, melodious and elegant, and quite aristocratic.

18, what is a waltz?

Waltz, also known as waltz, is also a kind of dance music in triple time. A folk dance originated in Austria. At first, it was popular in Vienna, and it was popular in Europe in19th century. Strauss's masterpiece The Blue Danube is the most famous. There are two kinds of it: brisk walking and slow walking. Unlike Mazzuca, which has three beats, its stress usually falls on the first beat of the bar. It is also different from the minuet with three beats. Waltz is characterized by lively rhythm and smooth melody, not as soft as minuet. However, it must be clear that music is neither mathematical nor logical, and this difference is only general, not absolute.

I hope it helps you. I have said it in detail, but there are too many. Or just copy a paragraph. Please adopt it.
