grace notes have different time. So you cannot actually work with grace
notes. But you may borrow the way grace note appearance. Try playing
around with the following and see whether you can make it do what you
want with some parallel voices (you need a separate Voice or the grace
note settings will invade your main voice).
graceOn =
\applyContext
#(lambda (c)
(for-each
(lambda (e)
(let ((ct (ly:context-find c (car e))))
(if ct
(apply ly:context-pushpop-property ct (cdr e)))))
(ly:context-property c 'graceSettings)))
graceOff =
\applyContext
#(lambda (c)
(for-each
(lambda (e)
(let ((ct (ly:context-find c (car e))))
(if ct
(apply ly:context-pushpop-property ct (list-head (cdr e) 2)))))
(ly:context-property c 'graceSettings)))
\new Staff
<<
\new Voice \scaleDurations 1/4 { \voiceOne \graceOn g'8[ a'] \graceOff }
\new Voice { c' d' e' f' }
