Rubato: Transcribing Piano Music with Timestamps

arXiv:2605.24291v1 Announce Type: cross Abstract: We consider the conversion of musical recordings into human-readable sheet music annotated with timestamps. Such output lets a listener clearly visualize rubato (temporally expressive playing), a learner diagnose ensemble precision and timing choices against the written music, and a musicology scholar compare performance styles across recordings of the same work. We introduce (1) a prompt-conditioned encoder-decoder model, named Rubato, trained to output (2) a new textual representation for polyphonic music, named InterMo, which we designed for

Why this matters
Why now

The continuous advancements in AI and natural language processing are enabling more sophisticated interpretations of complex data types, such as polyphonic music.

Why it’s important

This development could significantly enhance the accessibility and analytical depth of musical recordings, providing new tools for education, research, and creative industries.

What changes

The ability to automatically transcribe expressive musical performances with high fidelity and temporal accuracy changes how musical data can be processed, analyzed, and visualized.

Winners
