The basic music theory knowledge of music is as follows:

1. The level of the sound is determined by the number of vibrations of the object within a certain period of time. The more vibrations, the higher the sound; the less vibrations, the lower the sound.

2. The length of the sound is determined by the difference in duration of the sound. If the duration of the sound is long, the sound will be long; if the duration of the sound is short, the sound will be short.

3. The strength of the sound is determined by the amplitude. If the amplitude is large, the sound will be strong; if the amplitude is small, the sound will be weak.

4. The timbre is different due to the nature and shape of the pronunciation body and the number of overtones.

5. The musical sound system consists of tone series. The sum of sounds with fixed pitches used in music is called a tone system; the sounds in the tone system are arranged in ascending or descending order, called a tone sequence.

Benefits of learning music:

1. A joint study of neurology, psychology and physics in the United States found that music can not only calm beasts, but also have more benefits for humans. Benefits: Children usually like music as soon as they are born and respond to music as soon as they are born. Strong spatial reasoning skills can improve your logical thinking and problem-solving abilities, making you more likely to find a good job in the 21st century, because all industries will need people who can use high technology.

2. Learning music can make people think more clearly, concentrate more easily, and handle other aspects of life better. It can also effectively relieve various stresses and make people healthier.

3. In addition to being a form of entertainment, non-professional music learning can also be of great help in mathematics and other scientific subjects.
