Alignment: positions at which all three engines agree
Positions at which all three engines emit a label and, once spelling is normalised, write the same one. Selecting a row opens the corresponding bar of the score; closing it returns you to the same place in the list.
Agreement is not treated as proof of correctness. Every cell here carries the same locked textbook grade as on Disagreements, so three engines can agree and still be wrong together. The grading criterion is set out on Ratings.
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.
