Hi Eluze,
Thank you so much for your advice. I did manage to adapt the snippet you
recommended me and now my score looks fine, but here are my general thoughts
about this issue:
- I believe that this problem with acciaccaturas should be covered in the
documentation, since a regular user would expect this to be working (I could
not find a single mention of it in there, but this might be my mistake)
- I tried the snippet you recommend me, but it works only in very limited
cases. Have a look on the results of this code:
slash = {
#(remove-grace-property 'Voice 'Stem 'direction)
\once \override Stem #'stencil =
#(lambda (grob)
(let* ((x-parent (ly:grob-parent grob X))
(is-rest? (ly:grob? (ly:grob-object x-parent 'rest))))
(if is-rest?
empty-stencil
(let* ((dir (ly:grob-property grob 'direction))
(stem (ly:stem::print grob))
(stem-y (ly:grob-extent grob grob Y))
(stem-length (- (cdr stem-y) (car stem-y))))
(ly:stencil-add
stem
(grob-interpret-markup grob
(markup #:translate (cons -1 (* dir (1- (/ stem-length 2))))
#:draw-line (cons 2 (* dir 2))))
)))))
}
\new Staff {
\relative c'' {
\acciaccatura {\slash g8[ a b c ] } d4
\acciaccatura {\slash g8[ a b c ] } d4
\acciaccatura {\slash g8[ a b c ] } d4
\acciaccatura {\slash g8[ a b c ] } d4
}
\relative c' {
\clef bass
\acciaccatura {\slash d8[ c b a ] } g4
\acciaccatura {\slash d8[ c b a ] } g4
\acciaccatura {\slash d8[ c b a ] } g4
\acciaccatura {\slash d8[ c b a ] } g4
}
}
- Also, the automatic slurs should not exist, in my opinion. Even in
Mozart's music one can find examples where acciaccaturas or grace notes are
not slurred, and when it comes to contemporary music and extended techniques
things get even more complicated.
- On the other hand, there should be automatic beaming inside the
\acciaccatura { ... }, since this is the most standard form of writing grace
notes. If one doesn't want it, then she/he could simply use \acciaccatura {
\autoBeamOff ... }
* * *
Contemporary composers constantly use slashed notes, being them
acciaccaturas or regular notes, beamed or not, single or multiple, slurred
or not. This is a very important part of the contemporary music vocabulary,
and I think it should be important to address this problem with LilyPond.
