The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Results show improved musical quality and structural coherence, while additional analyses confirm higher efficiency and more effective capture of long-range patterns with the proposed tokenization.

C2weakest assumption

That discretizing music into uniform beat-length steps and collapsing same-pitch events within each step into single tokens preserves all musically relevant information without introducing unacceptable loss or ambiguity compared with variable-duration event encodings.

C3one line summary

BEAT tokenizes symbolic music by uniform beat steps with sparse per-beat pitch encodings, producing higher quality and more coherent music continuation and accompaniment than event-based tokenizations.
