Disagreements: positions at which the engines differ

Positions at which all three engines emit a label and at least one of them, after normalisation, writes something different. These are the rows that tell the engines apart. Selecting a row opens the corresponding bar of the score.

Positions at which an engine emits no label are not listed here. A missing label is a gap in coverage, not a disagreement, and counting it as one would distort the agreement rate.
Preliminary results. Every figure on this site is recomputed from the corpus pack at each build. On 15 September 2026 the pack was rebuilt after an alignment fault was found and corrected, and the textbook criterion was audited against the book — see Corrections. The textbook grades measure tolerant agreement with a label derived from musWM’s own reading of the chord; they are not an accuracy against an independent reference.
