Help for \beamExceptions

2015-09-01 Thread Richard Shann 
I've been trying to use the music function \beamExceptions which is in
version 2.19.25, I can't find anything much to document it though.
For example, trying this

\version "2.19.25"

MvmntIVoiceI = {
 e'8[ f'8 g'] a'8\noBeam b'8 a'[ g'8 f'] |
 e'8 f' g' a' b' a' g' f' 
}

\score { 
\new Staff {\time 4/4 \MvmntIVoiceI } 
\layout {
\set beamExceptions = \beamExceptions { \time 4/4  e' 8[ f' 8
g' ] a' 8\noBeam b' 8 a' [ g' 8 f' ] }
}
  }

the second bar is not beamed like the first, despite the music argument
to \beamExceptions being a copy of the first bar.

Is the next stop some source file for finding out what can be done, or
am I missing some documentation?

Another topic that came up while I was doing this:
I have used \set beamExceptions here, but I couldn't figure out what is
allowed for setting the context - Voice and Staff worked but \set
Score.beamExceptions was ignored, and I couldn't find out what \set
Timing.beamExceptions was doing - Timing doesn't appear in the hierarchy
of contexts...

Yup it does look different. Using \override Tie.Y-offset = #.3 fixes it a
bit but still ugly.

\beamExceptions only takes explicit beams.  \noBeam is useless here.

It's just notes and [ and ].

Timing is a context alias established by the Timing_translator.  There
is a hardwired alias Timing for the Score context in case you use Timing
before anything has been called.  The location in ly/engraver-init.ly
where this alias of Timing to Score (which is only relevant if you are
at outer Score level or there is no intervening Timing alias) states:

  \alias "Timing"

  %% An alias for Timing is established by the Timing_translator in
  %% whatever context it is initialized, and the timing variables are
  %% then copied from wherever Timing had been previously established.
  %% The alias at Score level provides a target for initializing
  %% Timing variables in layout definitions before any
  %% Timing_translator has been run.

Upon a close look it appeared that there was still a little displacement

Indeed.  I chose a few bars from Chopin's Première Ballade, Op. 23 to

Re: Help for \beamExceptions

2015-09-01 Thread Simon Albrecht 

Hello Richard,

if you want to use \beamExceptions, it seems like the only way to do this is
%%
\version "2.19.25"

{
  \time 4/4
  \set Timing.beamExceptions = \beamExceptions { 8[] 8[ 8] 8[]  8[] 8[ 
8 8] }

  e'8 f' g' a' b' a' g' f'
}
%%

– that’s a bit cumbersome and IMO it should lead to the same result with 
{ 8 8[ 8] 8  8 8[ 8 8] }.
So currently this is a case where the immediate, Scheme way is more 
straightforward:



\version "2.19.25"

{
  \time 4/4
  \set Timing.beamExceptions = #'((end . ((1/8 . (1 2 1 1 3))
  (1/12 . (1 6 2 1 2)
  e'8 f' g' a' b' a' g' f'
  \tuplet 3/2 4 { e' f' g' f' g' a' g' a' b' a' g' f' }
}


Yours, Simon

The first \stopGroup closes the smaller grouping, because the system is
designed so that brackets nest cleanly.

Interestingly, this overlap is possible with slurs:

%

\version "2.19.25"

secondSlur = #(make-music 'SlurEvent 'span-direction START 'spanner-id "2")
secondEnd = #(make-music 'SlurEvent 'span-direction STOP 'spanner-id "2")

\relative c'' {
  c( d c\secondSlur d) c d\secondEnd
}

%%

This, too:



thirdSlur = #(make-music 'SlurEvent 'span-direction START 'spanner-id "3")
thirdEnd = #(make-music 'SlurEvent 'span-direction STOP 'spanner-id "3")

\relative c'' {
  c-\tweak Slur.positions #'(4 . 4) ( \secondSlur
  c\secondEnd\secondSlur -\tweak Slur.positions #'(3 . 3)\thirdSlur
  c\secondEnd\secondSlur
  c)\secondEnd\thirdEnd
  c( d c\secondSlur d) c d\secondEnd
}

%%%

Maybe a system could be devised where brackets nest by default, but a
spanner-id property can be used to create more sophisticated structures?

You likely mean
http://lsr.di.unimi.it/LSR/Item?id=336

Though, please note, it's the "LilyPond Snippet Repository", LSR
The LSR is _not_ part of the manuals.
A lot of snippets are taken from the LSR and included in the snippets-manual.
That's not exactly the same, though ;)

> It doesn't work.

It does.

> What's the mistake, any idea?

If you use a snippet, you have to include the _whole_ snippet into your file
You deleted the entire definition of `merge-rests-on-positioning'!!!
Additionally, there are several mistakes in your code of the snippet.

Again, if you want to try a snippet copy and paste it in your file
_without_ any changes!
Try it and _afterwards_ you may try to apply changes.

Read the description:
"[...] Please note that multi-measure rests are not automatically combined"


There are engravers on the list you may want to try, affecting simple
rests and MultiMeasureRests, though they are not perfect, either:

Lyric in popular score

2015-09-01 Thread Marcos Press 
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?

All the things I found in google, the manuals and snippets always deals
lyrics starting at the same moment of the music.

What I need is

\chords { blah blah blah blah }
\music { blah blah blah blah }
\lyric { R2*15 r4. blah blah blah}

Do I have to break the music block into two blocks?

Can anyone point me where to look for an unswer?

Thanks in advance!

Hello Marcos,

first: welcome to the list!
Second: It almost always helps if you add a compilable, possibly tiny 
example  to your post – thus it 
will be easier a) to understand the problem and b) to give you a solution.
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.

But now to your question :-)

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

Hi Marc,

I wrote some test

m =
\relative c' {
  c1~ 1~ 2 s2
  \bar "||"
  c1~ 1~ 1
  \bar "||"
  c2~ 2~ 2~ 2~ 2~ 2
  \bar "||"
}

\transpose c c  \m
\transpose c d  \m
\transpose c e  \m
\transpose c f  \m
\transpose c g  \m
\transpose c a  \m
\transpose c b  \m
\transpose c c' \m
\transpose c d' \m
\transpose c e' \m
\transpose c f' \m
\transpose c g' \m

looks like the Ties are different only, if a whole note and one of a
different value are involved _and_ if they are on a staff-line.
With \voiceOne/Two Ties at the bottom and top-lines are affected as well.
The test-code above does not contain this, you may want to play around
with voiceXxx, though.
png attached.

I've found the `intra-space-threshold' form `Tie.details' can be
tweaked to improve the situation:


\version "2.19.25"

#(define (tie-tweak intra-space-threshold-value)
"
 Set @code{intra-space-threshold} of @code{tie}'s @code{details}-property to
 @var{intra-space-threshold-value}.
 Apply it only if the tied note is on a line.
 Limitation: works for default five-line-staff only.
"
  (lambda (grob)
(let* ((right-bound (ly:spanner-bound grob RIGHT))
   (staff-pos (ly:grob-property right-bound 'staff-position)))
;; apply it only if the right-bound is on a line!!
(if (member staff-pos '(-4 -2 0 2 4)) ;; works only for default-staff-symbol
(begin
  ;; for testing, set color:
  ;(ly:grob-set-property! right-bound 'color red)
  (ly:grob-set-nested-property! grob
'(details intra-space-threshold)
intra-space-threshold-value))) ;; default 1.25
)))


%% TEST-EXAMPLES


m =
\relative c' {
  c1~ 1~ 2 s2
  \bar "||"
  c1~ 1~ 1
  \bar "||"
  c2~ 2~ 2~ 2~ 2~ 2
  \bar "||"
}

\layout { \override Tie.after-line-breaking = #(tie-tweak 0.25) }

\transpose c c  \m
\transpose c d  \m
\transpose c e  \m
\transpose c f  \m
\transpose c g  \m
\transpose c a  \m
\transpose c b  \m
\transpose c c' \m
\transpose c d' \m
\transpose c e' \m
\transpose c f' \m
\transpose c g' \m


%% Your EXAMPLE


\relative c'' {
  a2. fis4 | a1 |
  <<
 { \voiceTwo g1 | fis | e | d~ | 1~ | 1~ | 2  }
 \new Voice
 \with {
   fontSize = #-3

 }
 {
  \override NoteColumn.force-hshift = #0.15
  \voiceOne bes'1 | b! | cis | d~ | 1~ | 1~ | 2
 }

}



I hope it helps a bit, although I've found no convincing general value.

Re: Lyric in popular score

I’m working on an answer…

Am 01.09.2015 um 22:34 schrieb Marcos Press:

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?

All the things I found in google, the manuals and snippets always 
deals lyrics starting at the same moment of the music.


What I need is

\chords { blah blah blah blah }
\music { blah blah blah blah }
\lyric { R2*15 r4. blah blah blah}

Do I have to break the music block into two blocks?

Can anyone point me where to look for an unswer?

Thanks in advance!

By this I actually meant the situation of textual critique, which with 
autograph(s) and different first editions is usually very difficult in 
Chopin. But of course it’s apparent that Chopin often uses notation 
which challenges the strict logics of LilyPond…

At least optically I can trick the collision away...

It's debatable, but it isn't in my edition (Augener),
but there is a footnote there which says:

"Klindworth has E flat, explaining that he found it
in an English edition, and he retained it in his,
because he liked the effect.  There is no doubt that
D is correct and I have thus altered it.  X.S."

I guess that makes those three bars all the more
interesting :)

Advanced note column handling…

2015-09-01 Thread Simon Albrecht 

Hello,

in a Mendelssohn score I encountered a problem on which I’m biting my 
teeth off. Have a look at the attachments – that’s easier than making 
many words. As you can imagine, the span stem should connect the two 
middle voices and the top two voices not collide (no matter in which 
direction), but I couldn’t yet figure out how: no combination of 
NoteColumn.force-hshift and NoteColumn.ignore-collision that I tried 
gave the intended result.

‘Is there, is there balm in Gilead?’ :-)

Yours, Simon
