Trying to typeset this 19th century arpeggio notation with a slash across a note. It's described:
"Chords marked as shown (see attached) are played as the preceding arpeggio chords, with the addition of a note where the oblique line is put, but the additional note is not to be kept down."
Any ideas if Lilypond already typesets this? I haven't had success searching the docs. Thank You! Javier
