The element of music is sound. Composers cannot express emotions clearly like words, but can only use sound to arouse people's emotions. The four basic elements of music are rhythm, melody, harmony and timbre. Rhythm reminds people of physical movements, and melody reminds people of spiritual emotions. Music expresses its emotions through differences in melody, speed of rhythm, pitch of sound, changes in harmony, and differences in timbre. For example, major keys represent happiness and majesty, minor keys represent sadness and melancholy; tense and short rhythms represent excitement and anger, gentle and long rhythms represent gentleness and softness, strong pitches represent enthusiasm, low and weak sounds represent tranquility; dissonance It represents struggle and dispute, consonance represents peace and tranquility; trumpet represents war, oboe represents pastoralism, etc. How to enjoy music? Everyone listens to music according to their own different appreciation abilities and hobbies. For the convenience of analysis, we divide the appreciation of music into three aspects. (1) Aesthetics: Listening to music is purely for the pleasure of music. It only seeks to be pleasant to the ear, and it is just a perceptual appreciation. It does not require any form of thinking. Let the appeal of music bring you into a fantasy realm. For example, when you are doing something, turn on the speakers and immerse yourself in the music absentmindedly. At this time, the appeal of music alone can bring people into an unconscious yet charming state of mind. Beauty plays a very important role in music, but it should not be allowed to take up too much place. Even at this early stage of listening to music, a more meaningful approach to listening should be adopted. (2) Expression All music has the ability to express, and there is always some meaning behind the notes. This meaning constitutes the content of the work and can arouse emotions. This is emotional appreciation. (3) Pure music: In addition to the pleasant sounds and the emotions expressed, music also exists in the notes and the processing of the notes. In order to follow the composer's ideas, consciously explore the structure of the music, changes in themes, and the use of the composer's techniques. This is intellectual appreciation and an advanced stage of music appreciation.
