Research On The Visualization And Classification Of Music Structure Based On The Representation Principle Of Partial Order Structure

In recent years,although people's life quality shows an upward trend,and life pressure also increases,which makes people pay more and more attention to personal health status and leads to higher and higher requirements for disease treatment.Therefore,some non-injury and non-traumatic treatment methods are gradually recognized by the public,and the music therapeutics have become the focus of attention of people and experts.At present,many countries combine music with medical treatment,and select the corresponding music for the treatment of specific diseases to achieve certain results.Some countries even put forward and explored the problem of classifying the music according to different medical needs and the characteristics of the music itself.To sum up,it is particularly important to analyze the internal structure of music and obtain systematic and standardized classification standards in medical treatment before using music to treat diseases.In this paper,the music is initially screened according to the 1/f wave theory,and the spectrum of the selected music is generated.In order to ensure the accuracy of good music screening,we use mutual selection method to achieve the spectral density map of the music on the basis of music expert selection,and select the music that meets the 1/f fluctuation rule,and then select different types of good music for the follow-up experiments.The intensity data values of the same frequency corresponding to the music at different moments are obtained by realizing the spectrum map of the music after screening.Attribute partial order structure diagram reveals the characteristics of different levels of things based on the philosophical principles of human cognition.Partial order structure diagram can not only find the universality of the existence of things from the macroscopic commonness,but also find the uniqueness of the existence of things from the microscopic individuality.Attribute partial order structure diagram can deal with a wide range of data and a large number of data,but the structure graph formed is not complex and has no crossover,which is an effective visualization technology to represent the relationship between things.According to the characteristics of the partial order structure above,this paper compared the granulation methods such as the average method,the median method,the random method and the whole traversal algorithm based on the mean by using the obtained data of the internal structure of the music.According to the characteristics of the data of the internal structure of the music,the whole-ergodic graining method based on the average is selected to process the data,and relatively abundant and effective partial order structure chart of the music attribute/object is generated,realizing the visual representation of the internal structure of the music at each moment.In this paper,the partial order formal structure diagram of music is formed through the above method,and the characteristics of partial order formal structure diagram of Chinese and western music,five-tone music,blessing bowl music and the same music in different periods are compared respectively.Partial sequence structure diagram provides a new idea for music therapy in the field of music classification and the visualization of the internal structure of music.
