Music structure design utilizing computer JavaScript

The computer programs designed for music creation are analyzed to integrate computer software into music creation.Then a computer program utilizing JavaScript is introduced, including the theoretical basis of JavaScript, the identifiers, and the basic syntax.Finally, the characteristics of JavaScripts in Max software are studied, and JazzB JavaScript objects are used to program and analyze the morphological changes of the rhythm structure of jazz.The results show that the designed jazzy structure includes many jazz instruments such as the piano, the guitar, the bass, and the saxophone; the rhythm of the melody varies five times, from 128 beats per minute in the beginning to 132 beats per minute in the end.In the whole melody, electro-acoustic instruments account for 62.5%, acoustic instruments account for 25%, and synthetic instruments account for 12.5%.Hence, the contents of the music is enriched and condensed, while its texture is also ensured.The accuracy of JavaScript has reached the last 5 decimal places and the running speed is Millisecond (105ms), which is more powerful than other programming languages.When using it for the design of music structure, it can have a better use experience, which is of great significance in promoting music design.
