Re: Change the duration of a chord defined as a variable
David,
I wonder if is there another solution for obtaining the same result,
because the discussed one is too much unstable. Here's the template, below.
I googled how to change a chord duration, but I found nothing.
chord = 4 -> \mp
newChord =
{
% add \chord with a new fixed duration and with its articulations
}
I was thinking about taking the articulations from each NoteEvent of the
chord, iterating with a (map (lambda (x) ), and putting them into a new
list, but it seems overkill to me...
What do you think?
Thanks for your help

Sorry for that. At any rate, try \displayMusic \mp in order to see the structures being used. Working with \displayMusic should help getting more of a clue about what happens here. -- David Kastrup ___ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user

Take a look at the PDF. They are there. And I'd suggest using
\displayMusic
on music expressions you want to see analyzed. "display" is unreadable
in contrast.

Re: Change the duration of a chord defined as a variable
Hi David,
in the snippet below, is it possible to set a new duration of \newChord in
the variable definition?
Thanks
chord = 4
newChord = #(make-event-chord (ly:music-property chord 'elements))
{
\newChord
}

Yes, I tried with:
%%%
chord = \mp
newChord =
{
<$@(ly:music-property chord 'elements) >8 $@(ly:music-property chord
'articulations )
}
#(display (ly:music-property chord 'articulations))
{
\newChord
}
... but it doesn't show articulations (I tried to display them with
"#display(...)" too and the list is empty). I don't understand how to pick
them

Have you even tried what happens with articulations?
Asking LilyPond should is usually the proper first recourse since it
means you waste only your own computer's time. As a bonus, you get no
complaints about top posting with full quote below.

Well, the lazy way would be
{
<$@(ly:music-property chord 'elements) >8
}

Great. Is there also way to add the articulations of chord to newChord ?

\version "2.18.0"
chord =
#(define-music-function (parser location dur) (ly:duration?)
#{ $dur #})
For recent 2.19, you can leave out the "parser location" blurb.
I am not sure whether this kind of usage might be common enough to
warrant creating an \etc syntax for it, like
chord = \etc
{ \chord 8 }
It might actually be desirable for guitar chord variants outside of
\chordmode. Or even in \chordmode.
