Hi Everybody,
here's a newbie question.
I tried to configure "merging automatically" of rests in polyphonic

It doesn't work.
What's the mistake, any idea?

Thanks very much!

Re: Lyric in popular score

2015-09-02 Thread Phil Holmes 
I'm not sure you're getting this right.  Singers sing words to the notes they 
have.  When there are notes with no words, what is the singer supposed to do?  
i.e. when you have given the singer a skip, what do they sing?

I'm supposing that you are not properly separating the notes for the singers 
from the notes for the accompaniment.

Hello Marcos,

first: welcome to the list!


  actualy... I've been in the list for a couple of years ;)

Second: It almost always helps if you add a compilable, possibly tiny

Third general remark: Are you familiar with the Learning Manual? 
 It’s a great 
resource for getting started with LilyPond and covers all the basics, also 
tutoring you on how to use the other manuals – so you shouldn’t miss studying 
that! It’ll be very rewarding.

  Dear list,

  Iḿ trying to add the lyric of a folk song to a score.

  How do I tell the lyric in wich measure to start?

There are two general ways to enter lyrics: 1) entering them with explicit 
durations and 2) automatically aligning them to a voice through \addlyrics or 
\lyricsto (or \set associatedVoice).

1) Use a skip of the required length to skip the first part of the music.
2) Repeat the skip as many times as there are notes to skip.

Example attached.

You’ll find that with the first method, the syllables are all left-aligned 
to the notes, at least if you use version 2.18.2 or earlier. This is a bug 
fixed only in the more recent development versions, so at least for the stable 
version you’re better off with \lyricsto.
In simple setups, \addlyrics may be used as well in place of \new Lyrics 
\lyricsto.


  Can anyone point me where to look for an answer?

The Learning Manual has a section on lyrics: 
, but the answer to 
your question is hidden deep in the Notation reference, in

  Thanks in advance!

You’re welcome! HTH [Hope that helps].

Re: lilypond: merging rests in polyphonic staff

2015-09-02 Thread Robert Schmaus 

> 
> I do not understand R1*4?

R is a full bar rest of the specified duration. Thus, R1 is a full bar rest 
that only makes sense in a 4/4 context. Duration-wise it spans the same time as 
r1, but is placed in the middle of the bar instead on the starting beat (or 
moment). Likewise R2 is a full bar rest in a 2/4 context, placed in the middle 
&c. 

Another difference: R1 * 4 specifies 4 consecutive 4/4 full bar rests, whereas 
r1 * 4 specifies a single rest whose duration is quadrupled. 

It's all covered in the notation manual, of course ...

No, it doesn't.  It specifies a total time span of 1*4 that is to be
filled with full bar rests.  If there are any measure length changes in
parallel music, this difference becomes relevant:

\relative
<<
  { R1*3 c'1 }
  { \time 3/4 c4 d e d e f \time 3/2 e2 f g  \time 4/4 c1 }
>>
> whereas r1 * 4 specifies a single rest whose duration is quadrupled.

Which tends to look strange.

Text centralized above a TextSpan

2015-09-02 Thread Caio Giovaneti de Barros 

Hi,

Is it possible to have text centralized above a TextSpan? I've already 
saw in the documentation text added in the middle of hairpins and of 
course there is a tuplet number or fraction in the middle of the tuplet 
bracket. But it seems that in Text Span this is not so easy to do.


Thanks!
Caio

Re: Text centralized above a TextSpan

2015-09-02 Thread Andrew Bernard 
Hi Caio,

Welcome to the list.

I am not sure how long you may have been following things, but this topic came 
up for me recently, and there is various discussion in the archives. In a 
nutshell, the answer is not really. It’s possible of course, but can it be done 
simply and easily, that’s the point. Presently I am working on a solution to 
enable lilypond to do this nicely. I came up with two half baked solutions, one 
involving modifying a text spanner, another modifying a markup, but neither of 
these is satisfactory. I am commencing some work to make an engraver to do the 
job.

I continue to be amazed how useful such a capability would be, and how many 
people request it. Certainly this sort of thing is all through the contemporary 
music scores I deal with. It’s something I hope to see incorporated into 
lilypond one day. As to timeframes for my solution - don’t hold your breath!

Andrew

Well, you can just jump in with the lyrics: the Lyrics context does not
need to start with \lyricsto (though synchronization is a bit queer if
it doesn't, but still easier than counting syllables).

\version "2.18.2"

music = \relative {
  c'8 c d c~ c4. r8
  g' e d c~ c4.
}

textExplicit = \lyricmode {
  \skip 1
  And8 now with words. _4.
}

textImplicit = \lyricmode {
  % the number after \repeat unfold is the number of notes skipped
  % the duration of the skip is ignored
  \repeat unfold 4 \skip 1
  And now with words.
}

textMixed = \lyricmode {
  \skip 1*7/8  % must be a bit short so that \lyricsto sees the next onset
  \lyricsto "melody" { And now with words. }
}

\score {
  <<
\new Voice = "melody" \music
\new Lyrics \textExplicit
\new Lyrics \lyricsto "melody" \textImplicit
\new Lyrics \textMixed

This helps a lot to see what you are trying to do. If I were 
transcribing this, instead of using \skip to get the lyrics to the right 
place, I would do this:

 1.   Create two music expressions, one for the intro and one for the
vocal part, and insert them in serial fashion in the same Staff context.
 2.   Put the Lyrics context in parallel with the staff, but assigned
specifically to the vocal part like this:


%%%

introMusic = \relative c' {
   | r8 ees \tuplet 3/2 { d16 ees d } c8
   | f4. f16 aes
   | c8 c ~ c16 c bes c
   | aes8 g4 ees8
   | d8 c \tuplet 3/2 { c d ees }
   | g8 f ~ f8. f16
   | f8 b, ~ b16 c d b
   | c2 ~
   | c2 ~
   | c4.
}

vocalMusic = \relative c'' {
 g8
   | c8 c16 c c8 c
   | c8 aes4.
   % etc.
}

vocalLyrics = \lyricmode {
   Cha -- ma -- va -- se Car -- men -- ci -- ta
   % etc.
}

\score {
   <<
 \new Staff {
   \clef treble
   \time 2/4
   \key ees \major
   \introMusic
   \new Voice = "soloist" \vocalMusic
 }
 \new Lyrics \lyricsto "soloist" \vocalLyrics
   >>
   \layout {}
}

%%%



FWIW,
Abraham

The other solution would have been
\new OneStaff { \new Lyrics \skip 1*8 \new Lyrics \lyricsto "..." {  } }
but, uh, the respective issue is still on review or countdown.

That one should be less awkward.  And the problem is that once a
\lyricsto iterator ends, its containing context is usually terminated.
So the thinking around the corner likely only works for a starting skip,
not an ending one.  I'll wait for OneStaff before doing any more
experiments, though.

If you compile this with

}

then the ties are drawn more evenly. It's interesting to see the changes 
when you comment out the indent line or ragged-right or both.


It looks as if lilypond needs some "space" to draw correct ties.

With ragged-right = ##t and c1~ 1~ 2 s2
you see the difference,
ragged-right = ##f and c1~ 1~ 2 s2 looks good (concerning ties).

perhaps) and it seemed to understand that - I haven't yet tried \grace,
it would be nice if that could be autobeamed, though perhaps that is not
possible. And there is a comment somewhere about using | to separate
something, I guess bars with the same \time signature (or, indeed
different ones).
I did have it barfing on empty measures (s1*4/4 perhaps) where the
underlying scheme errored without any pleasant LilyPond error message
resulting, I'm not sure if this is something that should be pursued...

Thanks very much for this insight into what is going on with Timing -
I'll be going on (hopefully) to make setting beaming patterns at Voice
and at top level available to Denemo users, so this will hopefully help.

That's really good to know - it will be easy to substitute \noBeam for
[] as the user creates the Beaming Rules from the selection in Denemo,
so that answers that need perfectly (well, assuming the [] syntax is not
just an accident of the parser - I don't recall seeing it documented).

Thanks v. much indeed!

Well.  Most of them are, but this one has a documented different return
type.  Should we call the superset of them LilyPond functions, or rather
bite the bullet and create multiple categories?

It isn't.

No, it's always for exactly one time signature, but at the time it is
called, LilyPond has no idea just how long a bar is and can't count it
off itself.  So you need to separate rule patterns by |.

Possibly, but it does not exactly make much sense to beam over that.

I've been thinking about this since you first sent it and it is starting 
to drive me crazy! I've poured over the code that creates the \note 
stencil and I can't find anything that would cause it to go crazy like 
this. The only font it even refers to is the music font, so I don't know 
why the \markup has a hard time with it. In the example you show (not 
sure if you are doing anything more complex in the actual score), the 
\markup doesn't use any text from ProfondoTupletNumbers at all when it 
draws the \note, so I have to assume the error is caused by the \markup 
command itself, though I haven't been able to prove that yet.

One way around this (at least to make it less of a typing hassle) is to 
remove the \override from the \layout block and instead encapsulate it 
in variables so you can use them on-the-fly, like this:

%

profondoTupletNumeralsOn = \override Staff.TupletNumber.font-name = 
#"ProfondoTupletNumbers"
profondoTupletNumeralsOff = \revert Staff.TupletNumber.font-name

%

It's probably more than you want to do, but this might be the best thing 
to do for the time being. Do you use the \note function in your tuplet 
markings a lot?

Best,
Abraham

I have my doubt it produces something useful, but when in doubt, you can
always check the results by writing
\void \displayScheme \beamExceptions ...

or by just replacing your call of \beamExceptions with
\displayScheme \beamExceptions and see what gets output.

Ah, in that case I need a way of building up the list of beamExceptions,
so the user can define beaming rules for all the time signature changes
they use in the score. My first attempt was this:
8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><

f'8[ e'8 e'8] }
beamExceptions_second =  \beamExceptions { \time 6/8  e'8 f'8[ b'8  a'8] f'8[ 
e'8] }

\layout {
\set beamExceptions = #(append beamExceptions_first beamExceptions_second)
}
8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><8><

but using \displayScheme I see that this results in

(make-music
  'ContextSpeccedMusic
  'context-type

  (make-music
'PropertySet
'value
(list (list (quote end) (list 1/8 5 3))
  (list (quote end) (list 1/8 4 2)))
'symbol
'beamExceptions))

Which I guess means that this is not creating a beaming rule specific to
those time signatures - can I augment the alist returned by
\beamExceptions to make it into a rule specific to the time signature
concerned? I guess I would know the answer to this if I could find out

Any value of beamExceptions only applies to one time signature, which is 
the one currently in effect.

  I guess I would know the answer to this if I could find out
what the alist holds initially, but my feeble attempt to elicit this via
\void \displayScheme #beamExceptions

Well, that’s by design :-)
The default values of beamExceptions for each time signature are defined 
in scm/time-signature-settings.scm – also the best resource for examples 
in dealing with the ‘internal’ Scheme data structure of beamExceptions, 
which is hard to grasp :-)

You can display the list of beam exceptions currently in effect by

getting ties to NOT avoid accidentals

2015-09-02 Thread robert edge 
Let's say I have something like:

{
\clef bass
cis1~ cis!1~ cis!1
}

I want all the accidentals to appear and I do not want the tie to be moved
really far away like it is now.  I preferred a few versions ago when it
would go right through the accidental.

I realize this is arguably crude and will make lovers of fine page layout
cringe.  

Nonetheless, is it possible to rig Lilypond to behave this way?

thanks!

You don’t really want the tie to cross the accidental, do you?
