Developed in the pluralistic environment of NYU’s ITP/IMA program, The Code of Music emerges from a need to establish a common creative language among students from radically different musical, cultural, and technical backgrounds—a professional composer from Mexico just learning to code, an Indian software engineer new to music-making, an Armenian industrial designer exploring sound for the first time. The project is shaped by the ethos of the creative coding community—one that has successfully welcomed broader participation through tools like Processing and p5.js—but which still sees a narrower cross-section when it comes to music and sound. This talk introduces The Code of Music as both a pedagogical tool and publishing experiment, designed to expand access to music technology. Description This talk presents The Code of Music, an interactive handbook that teaches the fundamentals of music theory through code and interactivity, guiding readers to create their own expressive musical systems. Designed for the browser, the book combines concise explanations, interactive illustrations, and editable code examples—from audiovisual theremins and probabilistic drum machines to weather-responsive compositions. By engaging readers in building musical systems, the project aims to bridge the gap between introductory creative coding and musical thinking. I will share my pedagogical approach, the structure of the book, and the technical pipeline behind its dual-format publication as both a dynamic website and a printable book.
