I don't get why this kind of diversity with overriding properties 
would have any purpose for a user. I mean, I see there are different 
sizes of notes between general score and tempo, but it's only that.




If I use, say, \easyHeadsOn or \aikenHeads in the main music, I
definitely don't want this to also occur in the tempo indication,
it would just make no sense. That is the reason why \rhythm
is intentionally not influenced by the main music or the usual
forms of a \layout block, but has its own places to define 
customizations,

the body of the \rhythm argument and the StandaloneRhythm...
contexts in \layout.

The difference between \note and \rhythm is a bit more arbitrary:
\note is the historical command while \rhythm is new in 2.24
and more flexible. Arguably, it would make sense for \tempo
to internally use \rhythm so that changing properties in 
StandaloneRhythm...

Jean,
Ahh... of course. I had forgotten that LilyPond doesn't require the 
braces for a single note, but does for anything more.




Well... that is true in a sense, but from the way you phrase it, I have the
impression that the underlying logic that explains why this behavior makes
sense is not clear to you.

Ok, let me try again. LilyPond thinks in terms of music expressions. This:

  a4

is an expression. This:

  a4 a4 a4 a4

is four distinct music expressions. The syntax of \volta is

  \volta  

so when you write

  \volta 1 a4 a4 a4 a4

it is parsed as

  \volta    1       a4    a4    a4  a4
  \volta  
      ~~~   ~~~
          



Now, when you have several expressions, LilyPond will let you
combine them. This:

  { a4 a4 a4 a4 }

is one single, compound expression that puts four subexpressions in
sequence, and this:

  << a4 a4 a4 a4 >>

is also a compound music expression, putting its four elements in
parallel. So, when you write

  \volta 1 { a4 a4 a4 a4 }

this is parsed as

  \volta   1        {   a4  a4 a4 a4   }
         
~~
  \volta        


Does that help?

To explain it by analogy, it's as if you had written

}

and expected \transpose to transpose everything after it.
That's not how it works. Unlike things like \clef and \time,

a music argument, so you need to write

{
  \transpose c' d' {
    a b c' d' e' f' g'
  }
}


If you don't put the braces in

\volta 1 a4 a a a

it's as if you had written


\volta 1 {

}
a a a


The notes after the first one are not included in the argument
to \volta, and thus not part of the volta, which makes LilyPond
legitimately confused.

Translating “Extending LilyPond” — any takers?

[Jean Abou Samra]

Hi,

[Sent to lilypond-user, BBCed to lilypond-devel]

After almost two years of promising myself I would integrate
https://extending-lilypond.readthedocs.io/ into the official
LilyPond documentation someday while never doing it, I decided
to officialize the status quo that it would be maintained separately
from the official documentation.

Now that it doesn't have a perspective of being translated inside
the LilyPond documentation anymore, it makes sense to translate it
into other languages in the repository where it lives. Today, I added
a little bit of infrastructure for that and put a stub for a French
translation, which I will probably work on at some point in the coming
months.

If you are interested in translating this into another language,
please let me know. The translation is done in .po files, like
most translation workflows (but not the one for the official
documentation).

Keep in mind that, from my experience, it is necessary to have some
level of familiarity with the content in order to do a translation.

The same goes for https://scheme-tutorial.readthedocs.io/,
which is currently available in English and French. Actually,
this one might be both shorter and less technical for a translator,
and more important to translate. However, the current translation
is from French to English, so I would have to "reverse" it. I'll do
this if anybody is interested in translating it.

Also, trying not to sound pretentious, I do think the extending guide
is not a completely insignificant part of the LilyPond ecosystem
today, as it is basically the only place other than LilyPond's
source code to learn about quite a few programming techniques. For
this reason, I am interested in increasing its bus factor. I'll
gladly grant access to anybody requesting it provided that I have
a little bit of experience working with that person. This applies
to the Scheme tutorial too.

Regards,
Jean

Simply insert a space between "x" and "8".



Also, the result will likely still surprise you because you are receiving
the argument "x" as ly:music?, which means a full note, with its duration
(implicitly taken from the previous duration if you call it as \accNote f
rather than \accNote f16 for example), so the "8" parts in the function
are standalone durations, which inherit the pitch from the previous note,
and you get something equivalent to

So better replace ly:music? with ly:pitch?. See also

I displayed your PDF at 60% size, and took screenshots of the pages.
The structure of the score is still plainly visible, but five pages
like this would take about 750KB to post instead of 14MB: of great

How to tell lilypond to look for variable "x" and make a 1/8 note out of it,
instead of looking for variable "x8"?

Thanks.

Lilypond in Termux (Android)

[Martin Tarenskeen]

Hi,

Recently I discovered that LilyPond is available for Termux, a 
Linux-like terminal app for Android devices.
Unfortunately it crashed my older (32bits) Samsung tablet, but it did 
run on my (64bits) phone. After my bugreport on Github something was 
fixed in the Guile package built for Termux a few days ago and now I am 
able to use LilyPond on Android. Hurray!


If you want to try LilyPond on your Android device: First install 
Termux on your device using F-droid instead of directly from Google 
Play Store. I think Termux is not updated on Google Play anymore.


Just wanted to share this with the Lilypond community.

Re: Override note properties in markup,note or rhythm

[| || | |]

Thank you for the really comprehensive answer! You solved a few other 
problems I was struggling with in the process.


I don't get why this kind of diversity with overriding properties would 
have any purpose for a user. I mean, I see there are different sizes of 
notes between general score and tempo, but it's only that.


Cheers!

Hiya!

I'm trying to find a gentle solution for the problem I encountered.

I overrided flag stencil in general Score, but it turns out that this 
doesn't influence notes in \tempo, \note and \rhythm functions. I 
there a possibility to influence those ones?


I add that I know I could construct note from the beginning inside 
markup and add hidden tempo change for proper tempo export, but it 
seems to be overkill for this kind of problem.



That overrides in the main music do not influence \tempo,
\note or \rhythm is intentional. However, \rhythm has more
flexibility than \note because you can just put overrides
inside it, like

\version "2.24.0"

customFlag = {
  \override Score.Flag.stencil = #ly:text-interface::print
  \override Score.Flag.text = \markup {\raise #-0.2 \beam #1.0 #0.05 
#0.5 }

}

\score {
  \new Staff {
    \overrideTimeSignatureSettings 4/4 1/8 #'() #'()
    \time 4/4
    \customFlag
    \tempo \markup { Mechanical (\fontsize #-1 \rhythm { \customFlag 8 
} \hspace #-0.6 = 92 )}

    c'8 8 8 8 8 8 8 8
    c'8 8 8 8 8 8 8 8
  }
}


It's also possible to do that globally with

\version "2.24.0"

customFlag = {
  \override Score.Flag.stencil = #ly:text-interface::print
  \override Score.Flag.text = \markup {\raise #-0.2 \beam #1.0 #0.05 
#0.5 }

}

\layout {
  \context {
    \Score
    \customFlag
  }
  \context {
    \StandaloneRhythmScore
    \customFlag
  }
}

\score {
  \new Staff {
    \overrideTimeSignatureSettings 4/4 1/8 #'() #'()
    \time 4/4
    \tempo \markup { Mechanical (\fontsize #-1 \rhythm { { 8 } } 
\hspace #-0.6 = 92 )}

    c'8 8 8 8 8 8 8 8
    c'8 8 8 8 8 8 8 8
  }
}


(Note the necessary extra braces in \rhythm { { 8 } }; this quirk has
already been solved, in the unstable version 2.25.0.)

Unfortunately, \tempo internally uses \note, which does not have the
same sort of customizability. You can use tags, though:

\version "2.24.0"

customFlag = {
  \override Score.Flag.stencil = #ly:text-interface::print
  \override Score.Flag.text = \markup {\raise #-0.2 \beam #1.0 #0.05 
#0.5 }

}

\layout {
  \context {
    \Score
    \customFlag
  }
  \context {
    \StandaloneRhythmScore
    \customFlag
  }
}

\tagGroup midi,layout

mus =
\new Staff {
  \overrideTimeSignatureSettings 4/4 1/8 #'() #'()
  \time 4/4
  \tag layout \tempo \markup { Mechanical (\fontsize #-1 \rhythm { { 8 
} } \hspace #-0.6 = 92 )}

  \tag midi \tempo 8 = 92
  c'8 8 8 8 8 8 8 8
  c'8 8 8 8 8 8 8 8
}


\score {
  \keepWithTag layout \mus
  \layout { }
}

\score {
  \keepWithTag midi \mus
  \midi { }
}



Best,
Jean

Re: Slurs not being followed in one vocal part

Hi Jon,

Thanks all! Separating the voices did fix the problem. I used this 
score a long time ago and then updated the layout, so I feel like an 
update several years ago must have changed the behavior, which is 
interesting.


Compare:

\version "2.24"

mel = \relative {
  g''4.( f8 f e) d( c)
  d2 r
}

lyr = \lyricmode { Glo -- ri -- a! }

stuff = {
  \dynamicUp % try commenting this out!
  <>\f\>
  s1
  <>\!
}

\new Staff << \mel \stuff >> \addlyrics \lyr
\new Staff << \stuff \mel >> \addlyrics \lyr
\new Staff << \mel \addlyrics \lyr \stuff >>

But if you remove the \dynamicUp you'll see that LilyPond's behaviour in 
<< \A \B >> \addlyrics { ... } constructions is a bit volatile.
