Abstract: In this paper, we explore the application of Large Language Models (LLMs) to
the pre-training of music. While the prevalent use of MIDI in music modeling is
well-established, our findings suggest that LLMs are inherently more compatible
with ABC Notation, which aligns more closely with their design and strengths,
thereby enhancing the model's performance in musical composition. To address
the challenges associated with misaligned measures from different tracks during
generation, we propose the development of a Synchronized
Multi-Track ABC Notation (SMT-ABC Notation),
which aims to preserve coherence across multiple musical tracks. Our
contributions include a series of models capable of handling up to 8192 tokens,
covering 90\% of the symbolic music data in our training set. Furthermore, we
explore the implications of the Symbolic Music
Scaling Law (SMS Law) on model performance. The results
indicate a promising direction for future research in music generation,
offering extensive resources for community-led research through our open-source
contributions.
