Hello,

You can also use an extra voice for breaks, as documented in NR 4.3.1 Line

Re: How to get warnings for unused parts of a file?

[Omid Mo'menzadeh]

I didn't know about $ at all! Where in the documentation can I find more
about it? It was hard to search for!

I tried it, but it doesn't seem to find my variable "vocal" defined in the
same .ily file. I tried using #(top-repl) and $(top-repl) too, in the #
version it knows what \vocal is, but in the $ version it doesn't.

In any case, I'm fine with defining that "main" variable, but I'm curious
about what's going on here.

Of course!I just attached two files that demonstrate the difference.

Well, that one's a timing problem.  You couldn't write

vocal = \relative c'' {
  a4 b c d |
}

\vocal

either.  The reason is that the assignment is not complete before
LilyPond has a chance to check whether something like \addlyrics { Ah }
follows, and so when it looks at the next thing that comes up to make
that decision, \vocal is not yet defined.  So there really needs to be
anything after that assignment that does not immediately reference
\vocal .

With #, LilyPond does not allow different syntactic functionality, so
when it sees # it does not bother evaluating it until after it has
completed the assignment, being sure that it won't have to add something
like \addlyrics ... to the expression to be assigned.

This is one case where minimal examples tend to fail more often than
actual use of assigned variables in practice, because usually when you
employ variables seriously, you don't reference them immediately right
afterwards.

Re: Transform notes in a variable?

[Craig Comstock]

Jean and others on this list, thank you so much for your help. It was so 
supportive! I was really surprised and pleased with how supportive this 
community was.

It was certainly challenging to learn so much so quickly but I have 
accomplished a score for general use, and also a specific viola part using the 
transformPitches Jean provided.

Performance tonight in Kansas City, MO, USA :) 

https://www.eventbrite.com/e/new-music-composition-concert-feat-ensemble-mother-russia-industries-tickets-169892660521

Source files, pdfs and a few rehearsal snippets are here:

http://unreasonablefarm.org/resonance/ 

I didn’t quite achieve ultimate re-use of materials between the standard score 
and the viola score but it’s close. One more little refactor would get me there 
but I didn’t have time just yet.

Cheers,
Craig

Re: addlyric

[Lukas-Fabian Moser]

Hi,

[Please keep the replies on-list, so everybody can follow.]


what if the note is not one but many?
See the very last word "jago" in the attached music score.


This requires no change in the lyrics you enter:

ja -- go

will do fine. But you have to tell LilyPond to create a melisma: For 
example, using a slur, or an explicit \melisma:


\version "2.22"

\relative {
  c'8 d e16\melisma f g f e f d g e'32 d c b a g f d\melismaEnd c4
} \addlyrics {
  Vir -- tu -- o -- so.
}

I really strongly recommend you work through the Learning Manual 
(especially the tutorial), most of your questions are answered there.

I'm just re-stating this to make sure I'm getting it right: Definitions are

see the definition once it's done? Am I right?

It's not a definition but an assignment, and the assignment is not
"lazy" but executed as soon as it is complete.  Recognizing its
completeness may require examining the type of the next token, and the
type of $ depends on its value (which consequently needs to be evaluated
to figure out its type) while the type of # doesn't.

Scheme function names

[David Zelinsky]

I'm trying get some facility with Scheme in Lilypond.  One thing I
haven't found in the manual is an explanation of naming conventions for
built-in scheme functions.  Specifically, why do some of them have names
starting with "ly:" and others don't?  Can someone explain this, and/or
point me to where in the manual it is explained?

End pedal optionally with text.

[Andy Bradford]

Hello,

I'm trying to  accomplish something similar to attached  image where the
sustain pedal ends without showing the line. In ASCII:

Ped. __/\

Optionally, it would be nice to follow it with something like:

Ped. __/\ con ped.

I've been able to eliminate the  bracket, but somehow have not been able
to get rid of the line:

Ped. __/\_

Using something like:

\version "2.18.2"
\relative c' {
  \set Staff.pedalSustainStyle = #'mixed
  a b c d\sustainOn
  e \once\override Staff.PianoPedalBracket.edge-height = #'(1 . 0) f 
\sustainOff \sustainOn g \sustainOff a
}

I've tried  altering Staff.SustainPedalLineSpanner but clearly  I do not
understand what it is for. Even hiding it has no effect.

Is there some documentation for this that I've missed? Any thoughts?

Thanks,

Andy

Hi Andy,

Notes:

1. It’s pretty old code, so there’s probably a better way nowadays…

2. It could (and should) be abstracted so that the “sim” is a parameter, rather

Historically, functions defined in C++ have a prefix of ly: .  It's not
really a distinction valuable to the user, and it is no longer
unilaterally the case.

Thanks, good to know!

I'd suggest putting a remark such as what you said at the top of the
Scheme Functions page (.../Documentation/internals/scheme-functions).
Otherwise it's pretty confusing to newbies.

Oh, maybe never mind.  It looks like it's just the development branch
(2.23) where that page has a mix of ly: and non-ly: functions.  In 2.22
it only lists ly: functions.  Maybe it's ok for newbies to be confused
in the devel branch :)

Subject: responses in hymn tunes?

Hello all,
I have a very specific problem I am running into of how to add a tenor response 
within the repeat of a hymn tune when there is also a response in the verses. 
Here is the hymn and my code. (I just copied everything... sorry if it is too 
much!)

When I have this situation, I create a lyric that has only the response.

I then I create a music line that has only the notes for the response (and 
actually, the pitches don’t matter).

Then, put the music line for the response into a nullVoice so the notes won’t 
show.

Finally, do \lyricsto to the nullVoice  with the response lyrics.

However, it appears that 2.16 does not have nullVoice (I’d push hymnary.org to 
move to 2.22 – but that may be impossible).  I believe you can use devNull 
instead of nullVoice with 2.16.

If you had given us a tiny example , ( https://lilypond.org/tiny-examples.html 
) I would have shown you an example. But this file is much too big for me to 
spend the time to work it out for you.

Best,

Carl

Re: responses in hymn tunes?

Sorry! I am still new, I havent made a tiny example yet... some of the
features of FlexScores only work with 2.16.2, so that is why Hymnary still

Understandable and unfortunate. It will be harder to get good help for 
older versions. Especially from me. Effectively all of my LilyPond 
experience comes after 2.18, so my advice won't be reliable for versions 
prior to that.

fret diagram number position

[Gary Brookman]

The position of the fret diagram number is confusing and I'd like to move it, 
but I'm not seeing a way. I looked at fret-diagram-interface but nothing is 
obvious for moving it towards the middle of a fret. Like this:

[cid:952f67fd-477d-41c4-949f-a859abaddc69]
Lilypond looks like this:

As Karlin wrote, you can use Ctrl+' and Ctrl+" to get those, they are
snippets in the Snippets menu.

And there is a tool in Tools→Programming→Special Characters, under
General Punctuation there are many special quotes which can be clicked
on to enter them in your LilyPond source.

Good luck!
