Slash region counts are numbers shown at regular intervals, either above or below slash regions, to help performers keep track of how many bars have passed. The intervals are usually based on typical musical phrases, such as every four or eight bars.
By default, slash region counts are shown in parentheses every four bars and are placed below the staff. Each slash region has its own separate count.
In Dorico Pro, you can change the start count of each slash region, how frequently counts are shown, their staff-relative placement, and whether counts are shown with parentheses, without parentheses, or hidden. You can also customize the count font style.
Note
Bar repeat, slash, and numbered bar region counts use the same font style.
