With technological advancements, artificial intelligence technology is also evolving, and the methods of music creation and teaching are gradually changing. In terms of creation, the earliest creations were completed independently by human creators, requiring extensive theoretical support. Meanwhile, the methods of music creation are constantly evolving and diversifying, and the AI collaborative creation model is gradually becoming the mainstream approach to music creation. This article explores four aspects: how AI assists human composition, typical models of collaboration between human composition and AI, the application of AI composition in music education, and the future development direction of AI music generation technology in education, thereby better understanding the role and value of AI in music creation and education. AI is developing rapidly but not yet mature. Technically, AI can effectively help us solve problems in creation and teaching, but there are still some controversies regarding emotional depth and copyright. Therefore, we should avoid relying on AI as much as possible when using AI.
