The Theory of Sound without Sorrow and Music", written by Ji Kang.

The Theory of Sound without Sorrow and Music believes that heaven and earth produce all things, and music is one of all things, and it is also produced by the way of nature and by heaven and earth. It is produced by the vitality of the world, so it is independent of heaven and earth and has its own "natural principles".

Its specific views on music mainly include 1. "Harmony is imageless" and "sound is impermanent" , that is, "sound" does not express certain feelings, and there is no necessary connection between it and feelings. 2. "Sounds have the harmony of nature and have nothing to do with human feelings." That is, the harmonious characteristics of music come from the nature of heaven and earth and are the " "The principle of nature". 3. "Sound is based on peace", which means there is no tendency to be sad or happy, that is, there is no sadness or joy. 4. "The sound is the result of restlessness and tranquility". It is believed that music can only rely on the movement of music. Changes cause emotional reactions of being restless or quiet when listening to music, but cannot arouse corresponding emotions. 5. "Sound" can make people "joyful and comfortable", that is, music can attract people with rich tones and make people's hearts move with the tune. And exercise, from which you can enjoy the beauty, feel satisfied, joyful and joyful.

"Soundless Music Theory" is another important treatise on music aesthetics after "Le Ji". It proposes and positively discusses the special characteristics of music. 2. In the book "Main Schools of Musical Aesthetics" published in 1929, the German theorist Gates first used the two names of autonomic music aesthetics and heteronomous music aesthetics. , to summarize the two views in Western music aesthetics.

The basic view of "Autonomous Music Aesthetics" is that musical beauty is a unique beauty unique to music. This is a kind of non-dependence, no The beauty that requires external content exists in musical sounds and the artistic combination of musical sounds. Music can only be understood as music, can only be understood through the music itself, and can only be appreciated by itself.

" "Heterometric music aesthetics" is based on finding the essence of music from the form, elements and composition of the music itself, rather than seeking the explanation of music from the connection between music and certain external objects. It is reflected in harmony, temperament The study of music technology theory such as science. What music shows is pure form. This form is not dominated by any external force. It transcends all specific images and concepts. It is the power of metaphysical thinking and a free and purposeless game.< /p>
