Music composition represents the creative side of humanity, and itself is a complex task that requires, abilities to understand and generate information in two axes: time and frequency. While demonstrating impressive capabilities in STEM subjects, current LLMs easily fail in this task, generating ill-written music even when equipped with modern techniques like In-Context-Learning and Chain-of-Thoughts. To further explore and enhance LLMs’ potential in music composition by leveraging their reasoning ability and the large knowledge base in music history and theory, we propose ComposerX, an agent-based symbolic music generation framework. We find that applying a multi-agent approach significantly improves the music composition quality of GPT4. We show that ComposerX can generate coherent polyphonic musical compositions with intriguing melodies, following user instructions.
Vintage French Chanson: Create a nostalgic chanson piece in C major with a slow tempo. The chord progression will be C, Am, Dm, G, played over 16 bars. Utilize accordion, violin, and upright bass. The accordion should lead with its melodious and expressive sound, the violin should add a romantic and wistful quality, and the upright bass should provide a warm, supporting foundation. This composition should evoke the charm and sentimentality of a vintage French chanson.
