The element of music is sound. Composers can't express their feelings as clearly as words, but only use the expression of sound to arouse people's emotions. The four basic elements of music are rhythm, melody, harmony and timbre. Rhythm reminds people of body movements, and melody reminds people of mental emotions. Music expresses its emotions by the differences of melody, rhythm, sound, harmony and timbre. For example, major indicates happiness and grandeur, and minor indicates sadness and melancholy; Nervous and short rhythms express anger, while gentle and long rhythms express softness, strong pitch for enthusiasm, and low and weak tone for silence; Discordant sounds mean struggle and dispute, while concordant sounds mean peace and tranquility; Trumpet represents war, oboe represents pastoral and so on. How to enjoy music? Everyone listens to music according to their different appreciation abilities and hobbies. For the convenience of analysis, we divide the appreciation of music into three aspects. (1) Aesthetic Feeling Listening to music is purely fun for music, only pleasing to the ear, only perceptual appreciation, without any form of thinking, and letting the appeal of music bring itself into a fantasy realm. For example, when doing something, turn on the stereo and immerse yourself in music absently. At this time, the appeal of music alone brings people into an unconscious but attractive state of mind. Aesthetic sense occupies a very important position in music, but it should not be allowed to occupy too much position. Even in this initial stage of listening to music, we should adopt more meaningful listening methods. (2) All music has expressive ability, and there is always a certain meaning behind the notes, which constitutes the content of the work and can arouse emotions, which is emotional appreciation. (3) Pure music is not only pleasant sound and expressed feelings, but also exists in notes and the processing of notes. In order to follow the composer's thinking, consciously explore the structure of music, the change of theme and the application of composer's skills, which is a rational appreciation and an advanced stage of music appreciation.
