Changing the position of grace notes relative to barlines

By default, grace notes are positioned after barlines and directly before the notehead to which they apply, including for the first note in a bar. You can position individual grace notes before barlines, for example, so the first normal note in the bar is not pushed too far from the barline, or to indicate that grace notes are played before the beat.

1. Select the grace notes whose position relative to barlines you want to change. You can do this in Write mode and Engrave mode.
2. In the Properties panel, activate/deactivate Grace note before barline in the Grace Notes group.

Result

The selected grace notes are positioned before barlines when the property is activated, and after barlines when the property is deactivated.
