What's new: A research team from China and the U.S. has introduced NotaGen, a symbolic music generation model that harnesses language model training techniques (pre-training, fine-tuning, and reinforcement learning) to generate exceptionally musical classical sheet music.

Key notes:

• NotaGen implements a comprehensive three-stage approach: pre-training on 1.6 million music pieces, fine-tuning on 9,000 high-quality classical compositions, and reinforcement learning.
• The system can generate music based on specific periods (Baroque, Classical, Romantic), composer styles, and instrumentation requirements through a prompt-based interface.
• Researchers introduced CLaMP-DPO, a novel reinforcement learning method that enhances musical quality without requiring human annotation, streamlining the optimization process.
• In subjective evaluation tests, NotaGen achieved the highest rating among comparable AI systems when judged against human compositions, with 41.7% of listeners favoring its output.

Why it matters: NotaGen represents a significant advancement in AI music generation by focusing on complete sheet music rather than just MIDI or audio output. This approach produces more musically sophisticated compositions with proper notation, making the technology particularly valuable for composers, music educators, and performers seeking stylistically accurate classical music generation.
