Generative AI-based music production systems are useful tools for generating text, images, and sounds, with particularly active use in the fields of text and image generation. However, most of these AI systems’ user interfaces (UI) does not yet sufficiently reflect user experience (UX) to satisfy users. This study aims to analyze the emotional vocabulary that is currently used in generative AI systems and to derive and compare the emotional vocabulary used by users to express the atmosphere of the music through experiments. This serves as a foundational study that demonstrates the necessity for more user centered development of emotional vocabulary.
