Music is a time art with sound as the carrier, and it is known as "flowing poem, intangible painting". Sound is the medium of music transmission, in other words, music expresses its meaning through the so-called invisible and intangible sound. The state of sound has always been erratic, and it comes and goes without a trace. Therefore, in the face of music, people often feel unfathomable and unreachable. However, it is precisely because of this that sound has a strong penetration. Successful music is not only full of passion, but also can connect everything with thoughts and emotions, and directly guide the listener's heart. Time embodies the special charm of music. Music is a process that travels through time. It always exists in a fleeting moment, which is both indescribable and intriguing. In the flow, music constantly develops, changes and combines, while at the same time, the listener is constantly capturing, for a time, expectation, satisfaction and forgetting coexist, and finally, through the ability of memory, imagination and understanding, it is integrated with each other. Music is usually the difference between singing and playing. It is divided into vocal music and instrumental music. Human voice is a natural and primitive sound, and it is also the most outstanding natural musical instrument. When performing, people often instinctively ignore the band at the beginning of singing; Instrumental music has extremely rich sound sources, which occupy most of the colors in the "color analysis" of sound, and has irreplaceable expressive power of vocal music. There are many basic elements of music, which have their own special functions, including melody, rhythm, beat, speed, dynamics, range, timbre, mode, tonality, harmony, polyphony, form, orchestration and so on. Here, melody and rhythm are the most important. Melody refers to a line composed of different sounds with different heights, lengths and strengths, which is common in the high-pitched part. It is the most important means to shape the image of music and is usually regarded as the soul of music. Rhythm refers to the rhythm in motion, which involves all aspects of "time" in music and is usually regarded as the pulse of music. It is these different musical elements that can change countless touching combinations in the hands of ingenious creators, thus realizing the purpose of depicting scenery, expressing feelings, reflecting social life and seeking the true meaning of life in music. Compared with other arts, music has always been regarded as the most mysterious and abstract of all arts. In art, only the beauty that can't be explained by words is the most valuable, and this is the magic of music. The famous poet Heine said, "The end of language is the beginning of music." Music language is very pure and essential. It expresses the truest connotation in obscurity and uncertainty, and it can reach people's hearts quickly. Therefore, music has always been regarded as an art that can "push people's inner freedom to the highest peak". How wonderful it is! The ancients in our country once praised it so much, describing the beauty and moving of music as "walking around the beam in the early hours of the morning, and never ending for three days", and affirming the social function and artistic value of music as "changing customs, not being good at music". Music has extraordinary strong fusion and appeal. In the wonderful sound stream, people from different countries and races communicate with each other, which brings happiness, and at the same time, music further evokes people's lofty quality and spirit.
