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 ?
