Background Music Generation depending on Game Situation using Text-to-Music model
Tougo Fujisawa, Makoto Murakami (Toyo Univ.) PRMU2025-44
Abstract (in Japanese) (See Japanese page) 
(in English) The objective of this study is to develop a system that enables independent game developers to easily create background music (BGM), which is often a significant burden in solo game production. Text-to-Music models can generate music from textual input; however, they require descriptions of musical attributes such as genre, mood, and instrumentation. For game developers without specialized musical knowledge, it is not easy to compose such musically detailed descriptions. On the other hand, it is relatively easy to describe the content of game scenes in natural language. Therefore, this study proposes a method for generating game BGM from text that describes scene information. Specifically, text describing the game scene is first transformed into text describing musical attributes using LLM. The resulting text is then provided as input to MusicGen, a Text-to-Music model, in order to generate the game BGM.
