I was just re-evaluating my grace note settings and noticed that Dorico can’t reproduce some of the settings recommended by Ross, Stone, and various style guides like B&H and Schirmer. Dorico’s grace note slash looks to be about 45 degrees. Boosey specifically recommends 35 degrees, and Ross (pg 190-191) and many of Stone’s (variable but pg 22) have a more shallow angle than Dorico’s. All of Schirmer’s (pg 47-48) have a more shallow angle too. It would be great if there was a way to modify the angle of the grace note slash to match these standards.
Stone (pg 22) and Boosey also show the slash on the upper right hand corner for a grouping of upstemmed grace notes with a rising line. I admit I hadn’t really thought about that one before, but if there are any future revisions to slash functionality, this would be a good feature to add too.
Here’s the relevant page from B&H:
