String players sometimes have to put one finger over two strings, but sound just one.
The finger also stopping an unplayed string is often played later, so this action is one
of finger preparation. I show this in the attached snippet where I have used a red note
head to denote the unplayed, but stopped note. Red looks a little vulgar and loud.
In the Kreutzer 42 Violin studies, this action is indicated with a blank square, something
like the end marker of a proof in mathematics.
Is there please any way I can change the note heads shown in red to a small blank square ?
