Music is a common element in almost all video games. Most music in games is written by a human composer, and played as a linear piece behind gameplay. Adaptive and/or Generative music systems can be used to extend the musical content or create new musical content using algorithms and AI. While there is research into these systems, there has yet to be an organized examination of their architecture and use. We present a taxonomy of generative music in games, to allow for examination and discussion of generative music systems. In doing so, we also present a survey of the current state of the art of generative music systems in games, and discuss challenges and prospects of generative music for games.

音乐是几乎所有视频游戏中的常见元素。游戏中的大多数音乐都是由人类作曲家创作的，并在游戏过程中扮演线性角色。自适应和/或生成音乐系统可以用于扩展音乐内容或使用算法和AI创建新的音乐内容。尽管对这些系统进行了研究，但尚未对其结构和使用进行有组织的检查。我们提供游戏中产生性音乐的分类法，以便对产生性音乐系统进行检查和讨论。在此过程中，我们还将介绍游戏中生成音乐系统的最新技术现状，并讨论游戏中生成音乐的挑战和前景。
