Music is an art that consists of sounds. It causes a variety of emotional reactions and emotional cries through human auditory organs. Music has no visual image and no clear semantics, but it can express people's thoughts, feelings and feelings about life, and can depict the scenery, images and even certain artistic conceptions of people and objects in nature, so it has extremely profound connotations. . The ability to appreciate music is closely related to the listener's knowledge and cultural accomplishment. The art of music is completed through the "trinity" creative process of composition - interpretation - listening. As a music listener, if you want to understand the content and emotions expressed in the work, you must first learn how to appreciate music. In his book "What to Listen Music", the famous American composer and conductor A. Copland divided the whole process of listening to music into three stages, namely the aesthetic stage, the expression stage, and the pure music stage. But in fact, when people listen to music, these three stages are interrelated, and the appreciation process cannot be mechanically divided into stages. But in this hypothetical stage, you can have a clear idea of ??the way to listen to music. The simplest way to listen to music is to listen purely for fun without any thinking, which is the aesthetic stage. It can be a kind of absent-minded immersion in music, while doing other work, while allowing the appeal of music to bring you to an unconscious but charming state. The four elements of music can stimulate people's emotions, and their appeal is extremely powerful. Therefore, the aesthetic stage occupies a very important position in music appreciation. It can bring you into the world of association and make you feel comforted or relieved, but You can't let it become a habit, because the value of music is not only the beauty it gives you. Only by adopting a conscious listening method can we get the true meaning of music. Listening to music requires understanding the meaning of the musical work. This is the second stage of listening to music, the expression stage. The meaning of music is to express emotions and emotions. The material of music is sound. It cannot express sadness or joy clearly like words, paintings and other arts. Composers usually cannot express it with specific words, nor can they relate it to something clear. Connection, can only use the expression of the voice to arouse people's emotions, so the feeling may be slightly different each time you listen to it again at different times. That meaning constitutes the content of the musical work, makes you excited, and resonates with you. Therefore, although music can use its expressive power to make you imagine and associate emotions, whether it is excitement, joy, sadness, or tranquility... there is no need to use specific words to explain what the meaning is. Even if you appreciate the title music, you should not be too rigid and bound by the title. The title only helps the imagination. In addition to the pleasant sounds and the emotions it expresses, music also exists in the form of notes and the processing of notes. This is the third stage of listening to music, the pure music stage. For musical materials, a work must be composed based on the principles of certain musical forms through melody, rhythm, harmony and timbre. Therefore, a listener must have and strengthen his/her awareness of musical materials and their development, and understand music. The principles of musical form, follow the composer's ideas, understand the ideological content of the work, identify the theme, recognize the characteristics, and further understand the overall layout of the music as the music changes and unfolds. This is the highest state of music appreciation. Of course, appreciating music is not only listening, but also imagining and associating. What is important when listening to music is understanding the musical works. The ideal music appreciator should be able to both enter music and transcend music. Just like a composer, he should have a subjective and objective attitude while appreciating music, be intoxicated by it, criticize it, and listen with a positive attitude. Otherwise, you will not be able to deepen your understanding of music.
