Decomposer: Learning to Decompile Symbolic Music to Programs

arXiv:2607.01849v1 Announce Type: new Abstract: Musical performance involves executing a set of high-level musical instructions, yet recovering those instructions from the performance is a challenging inverse problem. We present Decomposer, a post-training framework for symbolic music decompilation: the task of recovering executable, editable music programs from symbolic music. We instantiate the task as MIDI-to-Strudel decompilation, where the model takes symbolic MIDI as input and produces a program in Strudel, a music programming language, that reconstructs the input when executed. The task

Why this matters
Why now

The proliferation of AI in creative fields and advancements in symbolic music representation are enabling new approaches to computational musicology.

Why it’s important

This research opens avenues for more sophisticated AI-driven music analysis, creation, and manipulation, potentially transforming workflows for musicians, composers, and entertainment industries.

What changes

AI models can now interpret symbolic music not just as data, but as executable programs, enabling a deeper understanding and programmatic manipulation of musical structures.

Second-order effects
Direct

AI gains the ability to understand and generate music in a more structured, programmable way, moving beyond statistical pattern matching.

Second

This could lead to new tools for interactive music composition, generative music systems, and educational platforms leveraging programmatic music understanding.

Third

The integration of programmatic music AI into broader agentic systems could enable autonomous AI entities to compose, perform, and adapt music dynamically in complex environments.
