Translated Data: The ChatMusician project enables the LLaMA2 model to understand and compose music through a text-compatible musical notation system known as ABC notation, without relying on external multi-modal neural network structures or specialized lexical analyzers. This project views music as a "second language," achieving an organic integration of music and language. The uniqueness of ChatMusician lies in its combination of musical notation with natural language, allowing the model to process music as it would text. This innovative approach offers new avenues for music comprehension and composition, showcasing the potential of large language models in multi-domain applications.
