Each row is a composer. Hover or select a point for its full tempo word. Transparent bands show each composer's minimum to maximum tempo; short dark vertical lines show the median. The plots follow the catalog filters above.

Each point is one positive ledger record. Vertical spacing separates overlaps; tempo values stay exact. Quarter-note equivalents convert the printed beat unit to quarter notes per minute, measuring note duration rather than perceived pulse. Composer name variants are grouped. Repeated editions and uneven composer sampling are retained.
