🧠 Expanding Crossmodal Generation through Language and Transforming Creative Subjectivity - Theoretical and Practical Considerations of the "Text to X" Structure in the Era of Generative AI - Author: Ichinose Rei / Published October 2025 by studio Rei 🔍 Summary "Toward an era where writing becomes creation." Stable Diffusion, ChatGPT, Suno, Runway... Crossmodal generation (Text to X), which "generates everything from text," is changing the very structure of creativity. This dissertation (14 chapters) centers on "creation through language," and explores: Non-performative composition The theory of prompts as musical scores Separating fictional personas from artist images Re-enactment structures through self-covering Redefining copyright and ethics This is the first systematic study to document, from both theoretical and practical perspectives, the transformation of the "creative subject" in the age of generative AI. It was created as a "thinking book for the T2X era" for creators who work across genres, including music, video, illustrations, and writing. 📘 Content Structure Introduction: Generative AI and the Shift in the Definition of Creator Chapters 1-3: Cross-modal Generation and the Formation of "Creation through Language" Chapters 4-7: Lyric-Driven Production / Prompt = Music Score Theory Chapters 8-9: Recursion of the Expressive Subject through Fictional Personas and Self-Covering Structures Chapters 10-11: Copyright, Ethics, and Responsibility in AI Music Chapters 12-14: Adaptation to an Era of Short-Life Music / Educational Implications / Summary and Outlook Appendix: "Rethinking the Boundary between Humans and AI" 🧩 Perspectives Gained from This Zine Language-Centered Creative Design = Theoretical Support for Non-Performance Composition The Idea of ​​Treating Prompts as "Musical Score" Creation: "Designing with AI," Not "Created by AI" Clarifying the Creator's Own Ethics, Responsibility, and Copyright Position Systematizing a Theory of Creativity that Extends to Education, Institutions, and Cultural Practices 📎 Specifications Format: PDF (Zine version / 57 pages) Published: October 2025 / studio Rei Author: Ichinose Rei Target audience: AI music producers, theoretical researchers, and generative AI creators in general Keywords: #Text2X #generativeAI #AIcomposition #crossmodal #promptengineering #creativeethics ✨ From Ichinose Rei "You can create without playing or drawing. But no one can escape the question of 'what to design.'" Creative work in the age of generative AI boils down to **how to verbalize one's intentions**. This paper, spanning music, art, and literature, was written as a record of "an era in which words move everything."
